BEST PRICE PROMISE
The EP-5 is a preamp unit, based on the Echoplex. It provides a boost and includes a buffer. Add warmth and sparkle to your cleans, fatten up your dirt or single coils, use it for leads, or get extra nasty stacking gain. Switch between three different settings: glassy, fat and cranked! An internal charge pump doubles the voltage for more headroom.
Comes with a mystery knob.
Note: This device uses standard 2.1mm DC power jack for 9v center negative power. Isolated power supply is recommended. No battery clip.
