This was a fun project. Took elements of the ruby/gem/cricket/dumbleton and then put a Boing reverb in front of it because reverb but also this circuit requires a buffer. This uses a LM3864-N which you can drive up to 18V so I made the entire thing switchable which gives you a high headroom mode that is much better as a pedal platform or for cleans than 9v only.

I built it into both a table top 1590DD to pair with this oversized pine cab pushing a 10” Celestion VT Junior. I also have it in a 1444-16 built as a combo (also pine) pushing a Celestion Eight-15.

Really happy with the results.

Bad guitarist demo here (8” cab)

Finally finished the combo version today. Been wrestling with the faceplate finish. I need a laser.

Looking good! I did a laser etched wood panel on my latest build, my luthier friend spent a whole afternoon trying different settings and we both still want to give it another go eventually even though we got a couple of pretty nice ones the first time around.

A 1-5 watt tube one is definitely on my radar, but my 100 watt build took forever and depleted play money for a good while.
 
For anyone interested I just ordered a couple runs of boards. One v2.5 of the garage amp with dumble FET boost. Happy to trade / share for cost + postage.

Also I ordered a proto run of V3 which is the ruby taken to the extreme - all of the features above plus transformer coupled XLR DI out with a fixed 2x12 G12-65 cab sim. Figure out how to turn a $5 amp into a $150 amp.
 
Thanks for sharing the schematic! Is that voice control inspired by anything in particular? Or did you come up with it? Looks like a notch / mid scoop?
