I only used a 12ax7 in this because I wanted to be able to swap more easily.

The submini tubes I've played with sounded great. Let it also be said- you could build one with a submini tube in a tiny chassis and it would be amazing. It's plain aluminum with clear LED knobs, clear LED holders and bright blue and green leds. I used the PEM stud inserter at work and pressed in hard mounting points for the board so no screws show from the top of the pedal.

I'm sure it could be done neater on a PC board but I love turret construction and I had quite a few of the tiny gold turrets. I don't think I have any shots of the completed version but it got a little bit messier as I finished wiring it. Then again- switching from Gilmour to EJ mode on the fly would be gnarly. Of course, then you'd end up wanting different EQ and volume settings for each and it would get out of control. I would be tempted to bring the internal off-boost source trim to the outside as it could make the gain boost more useful. There is clearly a "sweet spot" on the tube bias knob where it sounds right other positions don't really work for me. I can't remember exactly which part values I used but there is a cathode pot mounted on the back face of the pedal, set up similarly to the Butler "bias" pot on the newest versions. It works quite well and can be adjusted to be just a gain boost or to get louder and much gainier.

I set the trimpot internally for "low gain" mode and the footswitch shorts the pot for full boost and high pass.

The jfet source bypass cap is in series with a trimpot with a footswitch across the trimpot. There is a jfet out front, a 2n5457 I think, driving a gain pot, followed by the grid stopper on the first triode. It's based mostly on the rackmount single tube version (with the black panel), but only loosely. It sounds every bit a tube driver, in fact it sounds quite a bit better than my old 4 knob one. I use it every Sunday at church, mostly in front of a catalinbread DLS but occasionally by itself. So would anyone like to join me in my quest? Anyone want a peek at the innards of these pedals in order to create some schematics? Or are they already posted somewhere on this site? I searched but couldn't find anything here. From what I understand, it's not one of the easier pedal projects to undertake. My ambition is to someday rebuild the newer five-knob version into a smaller box.

Apart from that, dynamic and tone responses from both are nearly identical.īeing pedantic about noise issues, I would prefer the newer one, except that it's really huge, way too big for my regular pedal board. It's barely noticeable, but the older pedal tends to be somewhat more saturated on the mids and also has more hiss/hum, while the newer one is slightly more transparent and quieter. Consequently, setting the drive knob at different levels impacts the tone controls so that they respond differently on each pedal. To my ears, to get the equivalent of an Eric Johnson setting (treble knob all the way down) on the new version, you have to set the older pedal at treble 4, mid 4, bass 5. I've got a 12au7 in the old one and a stock tube in the new one (no idea what it is). They're both just as good and the range of sounds available from each are pretty much identical, except that the knobs have to be set quite differently on each pedal to achieve the same sounds. Then I bought the new re-issue version and had an A-B comparison. I wrote to Butler's company and a technician there verified it as a genuine Butler pedal, as opposed to the Chandler "fakes." The other is a newly made re-issue with bias knob and built-in transformer, as endorsed by Eric Johnson.įor years, I thought the older one I had was quite different and inferior to the new stuff. One is an older (80s?) version with a black chassis and bright-yellow lettering and lines, and which requires powering by an external 12 VAC source. I've got two of these BK Butler Tube Drivers.
