    I sincerely hope the original builder didn't fry himself making this...uh...amp.

    Designing and building an amp based on the control-names of an fsbo faceplate is an intriguing idea.

    Better yet, just give the controls random meaningless names.

    I knew it! I got a swatch of that exact cloth off a Hammond and put it on an amp head I built a few months ago. It's great stuff, wish I could get more. 39575587_1870174033050588_4263174371822010368_n.jpg

    I like the idea of adjustable skank. I mean sure I loves me some skank. But sometimes it'd be handy to dial it down a bit, like for family events.

    oh come on, don't be so judgemental. Everybody starts somewhere, and they often start with little knowledge. We learn by doing. Whoever built this amp had the courage to build an amp. He may not have had advanced knowledge aboutn every detail of amp building, but he built an amp that works.

    Yeah, my first few efforts were pretty bad too!

    It had been previously identified as a kit. And it's a valid example of not doing minimal research before assembling it AND not following the layout included with a kit. So I'm "judgmental" - and three people judge ME.

    I agree we all have to start somewhere, but this is a very poor example of how to start. Not even the bare-bones assembly layout was followed. Sorry, but I do not consider it fair to jump me alone for pointing it out specifics about kit building when others called it "spaghetti" and a "rat's nest" and were left alone - why, because they didn't mention anything about electronics?

    easy, friend - it was not a personal attack. You are a great TDPRI friend and a truly knowledgeable source here. If you felt that I was attacking you personally, please accept my heart-felt apology. That was mot my intention.

    I know nothing about the amp, the builder, or the kit. I do know that I built many things that were wrong! I just recently rebuilt and amp that I built around 1995. I built it with scrap parts, and based it on a Vox AC-30 schematic. It fired up first time, and I used it for 5 years in weekly rehearsals and many live performances. But when I went to rebuild it (purely out of boredom, not because of any failure) I was SHOCKED at how poorly I had built it in the beginning. I had no idea, then, of lead dress. My soldering technique was horrible, my choice of components was based solely on availability. BUT - that amp worked, and sounded great.

    So in that post I did not mean to insult you; I meant to encourage others to start, to build, to make mistakes, and to learn from them. And I hope - and expect - that they will learn a lot from YOU.

    No judgement from me. Definitely very little thought or care put into this amp, no question, and shoddy workmanship all around. That said, my first attempts were not pretty either!

    If the quality is poor because it was constructed by an unskilled novice, it's forgivable. If, on the other hand, it's because of laziness, apathy, and poor attitude... well they just deserve a slap across the face with a moist trout.

    Maybe somewhere in between, that looks down right OCD!

    I hadn't looked inside an old Fender chassis in a while. I had mostly pondered my own builds and builds of others here on TDPRI, along with David Hoffman's builds and layouts, which are the quintessence of an OCD vibe, with all the right angles. Then the other day, I took out my Deluxe Reverb chassis to have a look at something. I was thinking of taking out the electrical socket and ground switch in the back of the amp and putting a mid control where the switch was. I decided not to, because I didn't want to re-do the power wiring, as it hadn't been touched since '76. But I couldn't help but notice my self-righteous :)) reaction to the lead dress and such. The horror! It's really cool to take in all the Shock Brothers expertise around here. It definitely makes for better, more reliable builds. But this reminded me that some of the best-sounding amps in the world were built around what @schmee calls the "in between." And that's pretty fun to realize.

    But hey, if you guys are taking applications to the OCD layout club, here's my latest... a Princeton Reverb chassis built on David Hoffman's layout.

    E6C8C57D-E505-4DEE-88E9-EBA0F994D0EC.jpeg Here’s some more OCD fun. This is an amp I built a few months ago. Fender Deluxe 5E3 output and preamp stages, Princeton power rail and reverb with extra gain stage, Ampeg Jet tremolo. I am as OCD as they come!:lol:

    Can’t get much cleaner than Hoffman boards!
