Thanks Frank!
The head is a stock 1966 JTM50 with EL34 tubes. At the time I did that, it had a set of old Mullard power tubes. I used a stock Marshall cab with original 25-watt speakers.
The biggest problem I have with this stuff is that unless you can get the volume up, the head sounds thin, and the speakers aren't moving air. I think I mentioned it one of those vids, but I do use a THD Hot Plate. That allows me to get the head up in volume so the preamp and power tubes are working, and then I can scale the overall output volume back.
Another thing is those heads usually have a bright cap hard-wired on the first input volume knob. (Same type of thing like on a Twin Reverb, but at least that's on a switch.) So, there it is again, the lower the volume on your amp, the brighter it is. And with a fuzz? Watch out. Razor blades!!!
My suggestion would be to try your rig with a Hot Plate on it. I love mine!
