This one is verified. Gibson Ga-5 circuit adapted to JFET's using a 2N5485 as a "Power Tube". Similar design to the Carmen Ghia layout I was trying to make, but this one works great.
I had to bias it a little hot to get a nice overdrive. It is very loud and breaks up nicely if biased around 5V.
I would have posted to verified layouts, but I am not legal there.
