The Homebrew Electronics Power Screamer is Homebrew Electronics' flagship pedal. It is based on the J$C4558D IC and is tonally wide-ranging and transparent. It "oozes" vintage, tube-like overdrive. It sounds best when ran thru the input of a tube amp. It is not meant to be run through an effects loop. Features true bypass.
Input-Instrument in. Unplug when not in use to conserve battery life.
Out-Out to amp
-9VDC jack-for use with -(Negative) center, 9VDC, filtered, and regulated power supply (not included).
Gain control-Varies the amount of overdrive.
Level control-Varies the amount of output. Capable of driving an amp in to saturation. Sounds best when ran a little above unity. (Louder with the pedal on)
Tone control-Varies the amount of treble.
Boost-Provides approximately 10db of gain/volume boost.
On/Off-True bypass of effect.
(Note: a small pop may occur when effect is switched
on/off. This is normal and is a trait associated with true bypass.)
Diode Select: Left-Classic overdrive-tight and controlled
Center-More bass, gain and volume, slight compression.
Right-Very compressed with tube like sag, warm, sounds like a small tube amp about to explode, best for single notes.)
Fat Boost Upgrade-The HBE Power Screamer with Fat Boost is an overdrive pedal providing
many different overdrive sounds and featuring the original JRC 4558 IC
chip and true bypass switching. The Fat Boost toggle can be engaged to
increase low end and gain. Works only when the Boost Footswitch is on.
