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.

    Hi,
    great project here! but there’s something I’ve never seen before! Can you tell me why you used a Schmitt Trigger? to lowering the noise?
    Really thanks,
    Best Wishes

    Its just one way to multiply the input voltage. Its a 6 times multiplier from someone named Renegadrian.

    In the Tube Groove video what are the differences between each of the sections you activate? Circuit? Tube?

  5. Thomas Hofmann says:

    The tube groove unit has the three versions you could build on a 1.3 board “at that time” !!
