This is a Pre-Owned Homebrew Electronics Power Screamer Overdrive. It is fully functional and sounds great. Built with a foot-switchable 10dB volume boost, three-knob layout of gain. level, and tone, and a three-way diode selector for an even larger palette of selectable tone, the HomeBrew Electronics Power Screamer Overdrive takes a classic sound and pumps it up with even more muscle and features.
Easily able to push out that mid-gain roar famous amongst effects aficionados, the Power Screamer's additional draw is its more compressed overdrive modes allowing for multiple voices out of one pedal.
