Dumpster Dive Tube Driven Boost/Overdrive Pedal #03

Introducing the Dumpster Dive! Powered by two vintage 12AU7 vacuum tubes, this pedal is Junkbox Amplification's modified and enhanced circuit based on the Valvecaster. Each footswitch activates a vacuum tube. Activating one of the tubes produces a warm gritty boost that is excellent for rhythm playing and beefing up riffs. Activate a second tube for a hot searing tone for lead playing. The Dumpster Dive features a gain control and volume control for each tube. Play with the settings for both tubes to dial in different tones. Two orange led's are installed at the base of the tube socket and illuminate when each tube is incorporated into the circuit via a foot switch.

This pedal runs on 12 volts DC, power supply included. This pedal is hand drilled and and hand point to point wired (no PCB's) by me one at a time. Since this pedal is point to point wired it is easily repairable when components wear out over time. The control knobs and labels are 3d printed in house. The U-bolt and extension spring tube cage protect the 12Au7 tubes from damage and the design draws its inspiration from early 1900's industrial motif.

The beauty of this circuit is that it also functions well with other tubes in the 9 pin 12 family. 12AT7's, 12AV7's, 12AU7's, 12AY7's, 12BH7's and 12BZ7's all work well in this pedal. This allows the user to try different tube combinations to customize to the desired tone. The differences in using the various tubes listed are subtle but noticeable.

The total cost of Dumpster Dive #01 is $150.00 minus and already paid $25.00 nonrefundable deposit. Shipping, two 12AU7 vacuum tubes, and 12 volt power supply included in the purchase.
