Please note: This includes the PCB only. Please see the bill of materials on the Synthrotek website for a complete list of parts needed.

Synthrotek's original Mean Screamer Pedal goes way beyond a typical tube screamer clone with a couple of great mods. We are using an original 4558 OP-AMP IC to give it that beautiful classic boost.

• The Brown tone mod adds EXTRA BEEF and Chunk!
• High End Boost Mod - Adds extra high end that sticks out in solos, etc.
• No Pop - a former version of the Mean Screamer had a loud pop when the foot switch was pressed; no longer!
• Hand-wire or PCB-mount the board (there are different assembly instructions and bills of materials for each):
• The PCB-mount version is designed to fit perfectly in a pre-drilled 1590B case
• The wired version lets you put it in any case you like
• Reverse polarity protection: if you plug in a center positive adapter, you won't fry the circuit
• Takes a standard BOSS style 9V Center Negative AC Adapter with a 2.1mm barrel (not included)

Why have two different versions? The PCB-mount and wired versions of the PCB use the same circuit and sound the same.

The PCB-mount version:

• takes less time for an experienced builder;
• fits in a smaller case and takes up less room on a pedal board.

The wired version:

• is easier to repair and solder and is recommended for new builders;
• can be used in a custom case;
• uses metal audio jacks instead of plastic.
