Carl Martin Dual Injection
Carl Martin · pedal
The Carl Martin Dual Injection is a dual transparent boost pedal housing two independent 12dB boosts in one enclosure that can be run in series or in parallel. The boosts are voiced for transparency, making the signal louder without significantly altering the core tone, so they work as clean volume lifts for solos, to push an amp into breakup, or to stack for greater available gain. Running the two stages together in series provides a strong front end shove, while parallel operation offers blended level control. It suits players who want flexible, uncolored boosting on a single pedal, whether for lead boosts, always on level setting or driving a tube amp harder without changing its character.
