Tube Preamp

The Big Trees is a valve-powered amplifier in a stomp pedal format. Two 12AX7s and one EL84 drive a 2.5 watt power transformer, making the Big Trees a full-fledged Class A amplifier.

Picture the Big Trees as an amp head in a pedal chassis. The circuit is styled as a non-master volume amplifier, with controls for gain, "root" and "branch" - bass and treble, respectively. Two knobs labeled Clean and Dirt control attenuation for the speaker output and the line level output. A six position Dirt switch interjects distortion into the clean signal, and also sags the power draw. Go heavy on the dirt, and the pedal will fuzz out - almost similar to a variac Marshall. Only at that point is the Big Trees similar to any other amplifier.
