"The Green Boost is a versatile tube pedal compatible with a variety of tube types, including 12AX7, 12AT7, 12AY7, and 12AU7. It can be used as a transparent clean boost or as a smooth, mild overdrive pedal. By swapping tubes and adjusting the bias control, players can tailor the pedal's headroom, response, and overall character to suit their playing style.
Thanks to its bias control, the Green Boost allows you to adjust the tube's headroom, shaping its dynamics and level of saturation. This makes it possible to achieve a harmonically rich tube overdrive, even at low volume levels.
The Green Boost can operate with a power supply ranging from 9V to 24V. Some pickups, such as humbuckers and P90s, require greater headroom to perform at their best. For this reason, a 24V power supply is recommended when using these types of pickups."
