Did you ever want to build a real tube pedal but you have been embarassed by the disadvantages:
- high, lethal voltage
- free wiring
- all the irritating schematics
then this is for you. Valv-e-tizer is a project
- running on 9V pedal power
- builds like any other effect circuit
- comes in different flavours
- is fun!
This circuit has gone through many revisions and surely can state that it has reached maturity now:
V1.1: adjustable plate voltage – discontinued. only few boards left. (Discontinued)
V1.3: adjustable BIAS voltage – new and better approach to control the tube character and amplification (Discontinued)
V1.4: like V1.3 but uses 6V regulator and the LED can be switched via your 3PDT.
V1.5: has additional mounting holes for supporting the tube socket during insertion/removal of the tube.
Make your solid state amp tube-soundish or use it as overdrive/distortion effect.
Update: Video demonstration of the Tube Groove which contains three different Valv-e-tizer boards.
Listen to the sound of real tube power. You hear a direct recording of the unit, no amp, no cabsim.
