Audio Kitchen The Big Trees - All Valve Class A Amp

Big Trees by Audio Kitchen

The Big Trees is a valve-powered amplifier in a stomp pedal format, hand built by Audio Kitchen expert sound technicians in West London. Two 12AX7s and one EL84 drive a 2.5 watt power transformer, making the Big Trees a full-fledged Class A amplifier. Simialr to the Flying Squirrel (TFS), TBT measures at 222mm x 145mm x 102mm (W x D x H), and comes with a long lasting and portable die-cast aluminum covering.

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 Audio Kitchen The Big Trees guitar pedal similar to any other amplifier.

Much like AK's range of amp heads, the Audio Kitchen The Big Trees preamp has a very unique tone and response.  It doesn't sound like a Marshall, Vox, or any other known UK-made amplifier.  Its Class A power stage gives it a quick attack, and the bias of the tubes adds organic, low-watt sponginess.  Cranked up, the Big Trees' volume level is perfect for studio or stage, and the user can also dial back for quieter at-home use without sacrificing dynamics.​
