Dual Compressor Limiter

Michael Pedersen — Mon, 23 Feb 2026 17:03:54 +0000

We built the Dual Compressor Limiter to give you control over the part of your tone most players find challenging: dynamics. When your clean tone feels uneven, when single notes disappear sooner than you would like, or when chords hit harder than intended, it becomes clear that dynamic control is not always easy to manage. Many players also want added sustain without sacrificing the initial attack and clarity of their playing.

This pedal is designed to address those challenges while preserving the natural character of your sound, delivering control and consistency without flattening your tone.

Dual Compressor Limiter gives you two completely independent compression setups in one enclosure. Each side has its own COMP and LEVEL controls, allowing you to set one side for subtle leveling and the other for stronger sustain or peak limiting. The shared THRESHOLD control ensures both sides respond consistently to your playing.

Used lightly, it evens out volume differences and makes your tone feel more stable and finished. Chords sit tighter. Arpeggios sound clearer. Clean funk becomes more controlled. Fingerstyle gains balance without losing articulation.

Push it further, and you get controlled sustain that holds notes longer without collapsing the attack. The low end remains intact. The top end does not turn brittle. Harmonics stay defined instead of smearing together.

The internal 12V operation provides increased headroom and stability. This means the compression remains composed even when your signal is strong. No sudden distortion. No choking of dynamics. Just controlled reduction where it matters.

The DRY blend control allows parallel compression directly inside the pedal. This is where the feel comes alive. You can add density underneath your signal while keeping your original pick attack untouched. The result is a tone that feels more solid under the fingers without sounding obviously compressed.

Switching between the two compression setups gives you instant flexibility on stage. One setting for rhythm consistency. Another for lead sustain. Both predictable. Both repeatable.

Dual Compressor Limiter is for players who want their tone to feel finished, controlled and responsive — not squeezed.

We build what we would trust on stage and what we would rely on in the studio.

CM Acoustic

Michael Pedersen — Mon, 23 Feb 2026 12:51:31 +0000

We built CM Acoustic with a clear objective: to create an acoustic amplifier that delivers controlled, full-range amplification while preserving the natural character of the instrument.

It is a 300-watt system built around two custom-designed SU65147CM 6.5 inch full-range drivers, developed and assembled in Denmark. Rather than reshaping the sound, CM Acoustic is engineered to reproduce it accurately. The amplifier maintains transient integrity, preserves harmonic separation, and retains low-end definition without artificial compression or exaggerated coloration.

Responsiveness is central to the design. An acoustic amplifier should not impose a signature; it should follow the player. When you play lightly, the system remains open and articulate. When you increase attack, the amplifier reacts immediately to the transient without adding edge or flattening the response. The initial pick impact stays defined, the body resonance remains stable, and the midrange does not collapse under dynamic pressure. Harmonics stay separated instead of smearing together as volume rises. The circuit tracks changes in touch with precision, remaining composed at higher output levels and controlled without becoming sterile.

The speaker system plays a critical role in that behavior. The SU65147CM drivers are specified for predictable electrical load, stable sensitivity, and controlled excursion. With natural resonance around 100 Hz, the cabinet delivers a tight and supportive low end without uncontrolled bloom. The ferrite motor structure maintains cone control under dynamic load, and the linear excursion range ensures the system remains stable when pushed. The result is a balanced projection that feels closer to a compact full-range monitoring system than a traditional acoustic combo, but without losing the immediacy of a dedicated instrument amplifier.

CM Acoustic features two fully independent channels designed for transparent signal handling. The instrument channel provides gain, a 3-band EQ with sweepable midrange from 220 Hz to 5.1 kHz, limiter, EQ bypass, reverb and volume. The microphone channel includes balanced XLR input with +48V phantom power, limiter and overload indication. CM Acoustic is engineered primarily for acoustic guitar, yet reproduces vocals and additional instruments with the same transparency. Each channel behaves consistently whether used independently or together, allowing precise level balancing without unintended tonal interaction.

For live environments, the amplifier integrates practical control features without complicating operation. The limiter manages peak dynamics, the phase switch assists in feedback control, EQ bypass provides direct reference comparison, and reverb can be muted via external footswitch. The balanced XLR DI output mirrors the amplifier signal path, ensuring consistent translation to front-of-house or recording systems.

The cabinet is mechanically reinforced with solid wood side panels, contributing structural stability and controlled resonance behavior. The enclosure volume is optimized for the specified drivers, ensuring predictable acoustic loading. The design remains refined and understated, suitable for professional environments while fitting naturally into a home setting.

CM Acoustic is designed, tested and assembled in Denmark. Component selection prioritizes signal integrity, stability and long-term reliability. We build what we would trust on stage and what we would choose to live with every day.

Premium Patch Cables

Michael Pedersen — Wed, 11 Feb 2026 13:09:50 +0000

When we designed our Premium Patch Cables, the goal was simple: deliver the cleanest possible signal in the smallest possible footprint. On a modern pedalboard, space is limited and signal integrity is critical — and patch cables play a much bigger role than many players realize.

Our Premium Patch Cables are built for professional use, where reliability, flexibility, and noise rejection matter just as much as tone. The flat cable design allows us to route cables tightly and cleanly, keeping pedalboards organized while reducing stress on jacks and connectors. Whether we’re linking pedals side by side or running longer connections across a board, the cables stay exactly where we want them.

We use compact, low-profile right-angle jack plugs to minimize wasted space between pedals. The gold-plated contacts ensure stable, low-resistance connections and help preserve signal clarity over time, even with frequent plugging and unplugging.

Inside the cable, a multi-strand copper conductor delivers a strong, consistent signal, while the dense shielding protects against noise and interference from power supplies, lighting, and other stage equipment. The result is a quiet, dependable connection that lets the pedals sound exactly as intended.

Carl Martin Premium Patch Cables are available in three practical lengths, making it easy to build tidy, efficient pedalboards — from simple setups to complex rigs.

Pro Power V2

Michael Pedersen — Wed, 11 Feb 2026 12:56:51 +0000

When we developed Pro Power V2, the objective was clear: deliver dependable, low-noise power for serious pedalboards — anywhere in the world. Whether we’re touring internationally or building a fixed studio rig, stable and properly regulated power is essential for consistent tone and reliable performance.

Pro Power V2 is built around eight fully isolated and regulated DC outputs, each individually selectable between 9V and 12V. Outputs 1–6 provide up to 150 mA per outlet, while outputs 7–8 offer extended current for more demanding pedals. This makes Pro Power V2 suitable for a wide range of analog pedals as well as many modern digital effects.

A rear-panel DIP switch allows us to set the voltage of each output independently. This keeps setup simple and flexible, without adapters or additional converters. The fused, switchable AC input supports worldwide operation, making Pro Power V2 equally at home on local stages or international tours.

Housed in our classic black metal enclosure, Pro Power V2 is designed for durability and long-term reliability. Each output is isolated and regulated to minimize noise, prevent ground loops, and protect connected pedals from overload or instability. The result is a quiet, predictable power foundation that lets the pedals perform exactly as intended.

Pro Power V2 can be used as a standalone supply or mounted beneath a pedalboard, and it ships with a selection of DC cables so it’s ready to integrate straight into a working rig.

DC Factory

Michael Pedersen — Wed, 11 Feb 2026 12:45:38 +0000

When we designed DC Factory, the goal was straightforward: deliver clean, reliable power for modern pedalboards — without noise, compromises, or limitations. Whether we’re touring internationally or playing local gigs, power quality matters just as much as pedals and cables.

Modern pedalboards increasingly include power-hungry digital pedals alongside sensitive analog effects. To meet that challenge, we designed DC Factory as a fully isolated, high-current power supply that stays completely quiet — even in demanding setups.

Instead of using a traditional toroidal transformer, we built DC Factory around a high-quality switch-mode power supply. This allowed us to deliver far more current in a much smaller and lighter enclosure, while eliminating radiated hum that can interfere with wah pedals and certain analog drive circuits. The result is a compact, lightweight unit that remains stable, cool, and silent.

DC Factory provides ten fully isolated DC outputs. Four isolated 9V power sections each deliver up to 500 mA and feed two outputs, while a dedicated 12V section delivers 500 mA to two additional outputs. In total, DC Factory supplies up to 2500 mA of clean, regulated power — more than enough for complex pedalboards with multiple digital effects.

Worldwide mains compatibility (100–240V) makes DC Factory ready for international use without adapters or converters. Built-in protection against short circuits and overloads ensures safe operation, while clear LED indicators provide instant visual confirmation that everything is powered correctly.

DC Factory is designed to be a dependable foundation for serious pedalboards — delivering stable, noise-free power night after night, regardless of where or how we play.

Ampster

Michael Pedersen — Wed, 11 Feb 2026 12:31:43 +0000

When we designed Ampster, the goal was to deliver the feel and response of a real tube amp in a format that fits modern playing situations. Fewer players rely on large amp rigs today, but the expectation of organic response, dynamics, and immediacy hasn’t changed. Ampster is our fully analog answer to that shift.

Ampster is a single-tube driven amp and speaker simulation that can either complement an existing amp or replace it entirely. There’s no digital modeling, no latency, and no menu navigation. Instead, we built an analog signal path that reacts to your playing the same way a traditional amplifier does — touch-sensitive, dynamic, and immediate.

The front panel mirrors a familiar amp layout. We included Gain and Master controls for shaping drive and output level, a full EQ section with Bass, Middle, and Treble, plus a Presence control for fine-tuning the high end. A dedicated Mute switch makes silent stage changes or tuning simple, while the Cabinet switch lets us choose between two speaker simulations: a 2×12 open-back cabinet or a 4×12 closed-back cabinet, indicated clearly by LED.

On the rear panel, Ampster is designed for real-world routing. We included a standard instrument Input and a Link output for feeding a traditional amp. A balanced XLR DI output allows direct connection to a mixing console or recording interface, complete with Ground Lift to eliminate hum. There’s also an effects loop for time-based or modulation effects that belong after the preamp, plus a Remote input for external cabinet switching from controllers like our Octa-Switch The Strip.

A subtle Voicing switch provides a low-frequency contour adjustment, allowing us to adapt Ampster easily to different guitars, pickups, or monitoring systems. Power is supplied via a regulated 9V DC input capable of delivering the current needed for the tube and analog circuitry.

Plug a guitar straight in, or place Ampster at the end of a pedalboard, and the result is a full, rounded clean sound with natural depth. As the Gain is increased, the circuit moves smoothly into a distinctly British-voiced overdrive, shaped by the guitar and pickup rather than imposed by the circuit. Our test players consistently report that Ampster feels like playing a real amp — responsive, organic, and inspiring — only in a pedalboard-friendly format.

Ampster doesn’t try to be everything. It’s designed to sound and behave like an amplifier first — because that’s what matters.

Octa-Switch The Strip

Michael Pedersen — Wed, 11 Feb 2026 12:10:51 +0000

When we developed Octa-Switch The Strip, the goal was to take everything we’ve learned from three generations of Octa-Switch and distill it into the most compact, stage-friendly format possible — without giving up control, transparency, or reliability. This is the most streamlined and advanced all-analog Octa-Switch we’ve built to date.

Designed and refined once again by Thomas Guldmann, The Strip keeps the core concept intact: eight true-bypass relay loops, programmable into eight presets, recalled instantly with a single footswitch press. Each loop uses impedance-free gold relays, allowing us to run any pedals — vintage or modern — without tone loss or compatibility issues.

The input can be set to true bypass or buffered operation. This lets us adapt the unit to anything from small pedalboards to large stages with long cable runs, while keeping the signal stable and consistent. Visual feedback is immediate, with clear LEDs showing both active loops and the selected preset.

Where The Strip goes further is in flexibility and layout. We added four external switching outputs, making it easy to control amp channels, multiple amplifiers, or other external devices directly from the unit. Everything is laid out in a long, low-profile enclosure that fits naturally along the front edge of a pedalboard — keeping foot access clean and predictable.

Programming remains hardware-based and dependable. Once the presets are set, they behave exactly the same every night. No menus, no screens, no firmware — just solid analog switching that does what it’s told, every time.

Octa-Switch The Strip is built for players who want total control over complex rigs, with the smallest possible footprint and zero digital compromise.

Octa-Switch MK3

Michael Pedersen — Wed, 11 Feb 2026 11:56:11 +0000

When we designed Octa-Switch MK3 together with Thomas Guldmann, the goal was simple: give players full control over complex pedalboards without tap-dancing, menu diving, or digital abstraction. We wanted instant access, absolute reliability, and a signal path that stays transparent no matter which pedals you use.

Octa-Switch MK3 is built around eight true-bypass relay loops. Each of your pedals lives in its own loop, completely isolated when not in use. Using the DIP switches for each bank, we decide exactly which pedals are active in each preset. Step on a single footswitch, and an entire combination of effects engages at once — clean, silent, and repeatable every time.

Visual feedback is immediate. Each active loop has its own LED, and each preset bank is clearly indicated, so we always know exactly what’s happening underfoot — even on dark stages.

To keep the rig flexible, we included a dedicated global Bypass switch. With one press, all eight loops are removed from the signal path, giving us the pure, unaffected sound of the amplifier. It’s the fastest possible way to reset the rig mid-song or between sections.

Octa-Switch MK3 also includes two external switching outputs. These can be used to switch amp channels, control multiple amplifiers, or interact with other external devices — making the unit suitable for far more than just pedals.

The input buffer is switchable, allowing us to run either buffered or unbuffered input depending on cable length, pedal choice, and personal preference. The output is stereo, supporting more advanced rigs without additional routing gear.

Programming is intentionally hardware-based. Once the DIP switches are set, the presets are fixed, predictable, and immune to accidental changes. For live use, we recommend covering the DIP switches after setup — not because it’s fragile, but because reliability matters.

Octa-Switch MK3 is housed in a solid metal enclosure and powered either by batteries or an external regulated power supply. It’s a professional loop switcher built for players who want maximum control with minimum complication.
