Dual Injection

Dual transparent boost pedal with independent controls and switchable serial/parallel routing for versatile signal enhancement.

Two independent transparent boosts derived from the acclaimed Hot Drive'n Boost, each with individual level control and true bypass switching for four different boost combinations.
Switchable serial/parallel routing modes: serial for single-chain placement, or parallel for simultaneous pre-drive and effects loop boosting without additional cabling complexity.
Versatile signal placement allows boosting clean tone, pushing drive pedals for increased sustain, or enhancing gain channels both before preamp and in effects loop.
High-quality transparent boost maintains tone integrity without coloration, preserving your ultimate sound while adding precise gain control wherever needed in the signal path.
Diecast metal enclosure with custom paint, large easy-to-use knobs, bright LED indicators for each boost, and true bypass switching for reliable professional performance.

All about Carl Martin Dual Injection

As guitar players, we all have that moment where we think, ‘How can I do this and still remain analogue?’ Once we have achieved the ‘ultimate tone, how can we boost that same tone without changing the quality? What if we want to boost the signal before your drive effect in order to increase sustain, or have a boost in front of your gain channel and another after the pre-amp in the effects loop? Well, Carl thought about this for quite a while and is now happy to introduce the super cool….’Dual Injenction’! Carl took the high quality, transparent boost from the Hot Drive’n Boost, and put two of them into one pedal. Each has it’s own level control and ‘True Bypass’ switch, plus there is another toggle which switches the Dual Injection between Serial and Parallel modes. In Serial mode, you use the Input/Output 1 on the back of the pedal and place the boost wherever you want in the signal chain. In Parallel mode, connect the Output 1 before your Drive or Preamp, and then use the Input/Output 2 on the side of the pedal to connect to your effects loop on the amp.

So, what does all this do for you? Well, the Dual Injenction gives you 4 different Boost settings…

1) Your normal set up either clean or with effects
2) Boost 1 engaged to a desired setting
3) Boost 2 engaged to a different setting than Boost 1
4) Both Boost 1 and Boost 2 engaged at the same time!

The Dual Injection is a high quality effect that can be powered by 9v battery or with the correct power transformer (we always recommend that you use a regulated power supply like the Carl Martin Pro Power).

The effect is housed in our diecast case with custom paint, True Bypass Switching, large easy to use knobs and bright LED indicators for Boost 1 or 2.
