These are my Carl Martin pedals, sold the rest so I'm down to this couple:
The manufacturer deemed them as vintage grade but the voicings are contemporary; no time-traveling here. DC Drive is a self-boosting unit, it eliminates the use of another pedal to boost the drive servings as there is an integrated boost feature. The Crush Zone screams metal, it loves drive supplements because it's not (BOSS) Metal Zone grade; very crunchy but intense so don't expect any (BOSS) DS-1 voicings either.
The Carl Martin chaps are also serious about product packaging as seen above; a (tough) plastic & foam side guards make sure the pedal doesn't wobble in the box.
