Build Level: Beginner
Based On: Ibanez® Tube Screamer™
The BeanScream (based on the Tube Screamer™) is the successor to the GreanBean project
which was offered on madbeanpedals from 2013-2023. This version adds a couple tweaks to offer
options beyond the core TS tone, but still retains all the classic settings of the stock circuit.
VOL: Total Output.
TONE: CCW is a treble cut, and CW is treble boost.
DRIVE: Gain amount.
SUBS: This control blends in extra bottom end at the clipping stage. It also increases the
overdrive amount.
CLIP: Selects between silicon (stock), mosfet or LED clipping.
