Nine of the most iconic green overdrive versions in one pedal. Let the Bonsai help you find your overdrive zen.


VOLUME – Controls the output volume. Left is less volume, right is more.

TONE – Controls the tone of the pedal. Right is brighter, left is darker. The Tone control is disengaged on the OD-1 setting.

DRIVE – Controls the amount of overdrive. Right is more, left is less.

VERSION SELECTOR – This knob selects between the 9 different versions.


OD1 – Overall, a brighter and slightly higher gain mode that does not utilize the Tone knob. This mode inverts signal just like the original, and it has asymmetrical clipping. The OD-1 is magical at boosting other drives or amps into singing saturation.

808 – The classic low gain with that signature pronounced midrange.

TS9 – Nearly identical to the TS-808, but with a midrange pushed slightly lower.

MSL – Though metal is in the name, this doesn’t quite inspire the modern metal/djent sound you may be expecting. Still, it has a higher gain sound with more low end, and an overall gooier feel.

TS10 – Made famous by John Mayer, this model from the late ’80s is a slight upgrade from the TS9. Bluesy and crisp, it has more low end roll off and low gain.

XR – The EXAR is a Polish made TS-style pedal that has a slightly different drive character with a little more gain than the classic Screamers, as well as a slightly more transparent feel.

TS7 – The hot mode on this version gives you the highest gain sound in the Bonsai. More low end and dirt fill out the tone. You’re now free to shred away.

KEELEY MOD PLUS – Robert Keeley’s classic mod tightens up the tone on the original, giving you smoother mid range, high frequencies, and increased bass response.

JHS STRONG MOD – Our own mod we’ve been doing since 2008, it is much cleaner and, overall, more powerful. The mode has more pronounced high and low end drop offs.

POWER – Uses 9V DC Negative Center. Do not use more than 9V DC. Your warranty will be voided. 100mA max consumption
