This is not your father's overdrive (12AX7). Expect something better, with a triode driving pentode into clipping. Tons of bloom and tube feel.

No semiconductors in signal path. No digital. No surface mount.

Built this to test out my TUBIFIER STEREO. Mono input converted to stereo, then stereo output from pedal switch selected to mono. This way I can simply adjust both channels for a perfect 0dB gain.

Always something in the works! Will eventually need a replacement enclosure for FRYBABY, but I'm also thinking of another tube buffer, this one with 1% distortion at 2Vrms. Why? To mimic the sound of an expensive single-ended-triode amplifier without spending a fortune. Anyhow, another brain fart led to the idea of making a transimpedance version of BUGLE...

I worked out a common enclosure and styling for all three products. Trying to keep costs down and performance up, they will all sort of look like a PICCOLO ZERO but larger.

For the BUGLE ZERO, all I have to do is replace the first stage with that from the PICCOLO ZERO and fine tune resistor values. Why? Because the Dos Locos cost $11,000 and I can do it for about $349...

Sad story with a happy ending...

While I was away on vacation a few weeks ago, my tube dealer sold out their entire stock of 6088 tubes (all 18,000 of them), which is what I had designed the TUBIFIER around. Hence, it is now a limited production run.

How to move forward? Pivot. Found me a new tube, the 6BF7 with better characteristics and no microphonics. Enough in stock. Not only that, but it is a dual triode, which means I can make this a stereo pedal. Take that VALVULATOR!

Pedal will be same size, same cost, but with no LEVEL control. Gain will be adjusted to unity internally for an always on 1:1 tube buffer. Switchover will likely be sometime in October.

Please welcome the STEREO TUBIFIER...

I've been working on this for quite some time. Tube (no longer in production) has both triode for gain and pentode for output, delivering both a warm preamp channel and a totally kickass overdrive channel full of sag and compression. It will become your favorite pedal...

New idea, new breadboard up and running! My thinking here is this is a more dramatic version of the BARITONE, which is a clean tube buffer for un-sterilizing your digital HiFi signals.

This new version will have no k***s, just pre-set unity gain and a lot more single-ended distortion. Right off the bat is is about 1% even-order harmonic distortion at 1V output. I'm aiming to do that at 2V (same as DAC output level).

The idea here is to allow you to get the same tonality and response of a big expensive SET amp. A 300B amp will set you back thousands. This buffer will get you that same distortion characteristic and compression for hundreds. Place it in front of your powerful SS amp. I will add a bypass so you can turn it off when not needed.
