Recreates the magic of the EP-3's front end, featuring a Field-Effect Transistor (FET) just like the original and following the exact same signal path. The gain control boosts your signal by up to +11dB, with light asymmetrical clipping at higher settings for a bit of nice organic grit. Power management circuitry guarantees constant headroom performance throughout the normal life of a 9 volt battery. Heavy duty Phase 90-sized housing, replica EP-3 - chicken head" knob and status LED. Built to take a beating on the road so you can leave your fragile vintage piece at home. True hardwire bypass. Powered by 9volt battery or AC adaptor (ECB003).
