The Carl Martin Surf Trem has received a facelift from the boys in the back. The 2018 Surf Trem gets its circuitry from the famous Carl Martin TremO'vibe and takes you back to those infamous American amplifier tremolos .... but wider, deeper, yet smooth with no noise or coloration. Clean, transparent analog trem.....just what you would expect from Carl and the boys. The new 2018 Carl Martin Surf Trem has head mounted Input/Output/9v, a very cool small footprint two tone anodized diecast case, the same heavy duty switch and the awesome Carl Martin DC/DC converter circuitry that allows the pedal to run with +-12v internally while still being powered by a regular 9v 200mA external power supply. Bigger sound, bigger tone, all analog, all Carl Martin!
