Playing aside, there were some clean tones that sounded reasonably good, and in skilled hands, would shine through. But then he turns it up, and the harshness shows up. It could also be blocking distortion. He doesn't have a tone control so he's getting a ton of signal that would normally be attenuated through a tone stack of some sort.
Never occurred to me he designed his own circuit, I just figured he copied some schematic like sophomores like me do. I'm which case all is forgiven, a most valiant effort on all fronts. But if he copied a schematic then tough luck show-off boy, you got to know how to pick 'em before you put 5000hrs into building it. Or get on first TAG and ask us :lol:

You know, as for getting good clean tones, that’s not really that tough, especially if it’s clean at a modest volume. IME if an amp sounds great cranked the clean is in the bag, but if an amp sounds good clean that might be all you have. This is for vintage styles, when it comes to amps w/ 24 knobs I’ve no idea.

I fully agree about the difficulty w/ little SEs especially w/ EL84s. I’ve decided EL84s aren’t all that special unless you have 4 of them. For me there’s only one little SE that plays in the tone big leagues and that’s the 5F1. I wouldn’t chase a BF/SF Champ out of the house either. And whenever I hear a killer little Chicago Valco type it's also always a Champ style circuit. But I haven’t heard everything. Otherwise, I think small cheap SS amps easily beat out tube bedroom amps.

Yeah, when he was cutting those carbon panels I also noticed no mask or respirator.

When I was in construction we always wore masks around hazardous material and particulate materials.

Be it silica sand (silicosis) fiberglass, lime, asbestos (phased out in the mid 70's but still found in older buildings.

We all do dumb things when we are young, but this stuff will affect your life forever if enough gets in your lungs.

I've seen this video before. He definitely has some great woodworking and fiberglass skills, but I've found that a solid plywood cabinet with black tolex is the most practical cabinet. I don't have the patience to build something like that, I'm too excited to see how the amp I just built sounds. I wouldn't want to see someone set their beer down on that amp. :lol:
