Tube Drive Twin Triode Dual Overdrive

Both triodes of that valve run in series Class A into a tweed-style tone stack based on a 5E3 Fender. Use either side alone or stack them. The pedal ships Drive into Tube; hold the Drive footswitch for two seconds to flip to Tube into Drive.

The Phat Mod side is based on the JFET BOSS BD-2 Blues Driver. Stacking the two sides reaches heavy saturated territory. The Drive channel is the more aggressive of the two.

A tube extraction pin and Allen key are included for valve changes.
