Independent shopping perspective
The Korena take
The Ram's Head Big Muff Pi revisits the 1973 Violet Ram's Head version in a distortion and sustain pedal format. Its voice is defined here by clear separation between strings and extended sustain, giving players a focused way to work with that circuit’s sound. Modern conveniences include true-bypass switching and an LED that shows when the effect is active. A 9V battery is included, with support for the optional EHX 9.6VDC 200mA power supply.
Strong match
Who this is for
- Guitar parts where sustaining notes and distinct separation between strings are central to the effect.
- Pedalboards that benefit from true bypass and a visible on/off status indicator.
