Same spec with 47u // 820 and 1n // 470k? Sounds about right. I like the way it compresses and crys a bit. The recorded tone is a tiny bit stiffer in the low mids. Might go back to 2k7 instead o 3k3 to clean that up, if you feel like it.

I remember to hear in a interview or something that Frank said that he was interested in a mod that can give you all the sounds without the channel switching (not very implemented in that era, remember that Tim and Frank modded the amps before even Soldano were building the SLO) just by rolling off the guitar volume

I thought that was more about his later mods, but not sure.

I tend to look at mods like versions of "something". To me this is kinda like a 2203/SL hybrid. The 2203 had already been around for a while, but it seems to me that in LA people preferred the Jose or Lee Jackson or Caswell or Levi thing to the stock 2203s. Still features of the 2203 layout are present in several of the mods.

Who knows, Frank didnt talk too much about the #36, the just told me about some values and the history that he made the 36 because they needed another amp and this things we all already know
I wonder why he did not talked so much about this considering its the most famous mod he had... he always seemed to care more about the MK2 mod

Yeah, it’s kinda weird. To little to late maybe? He never got full credit outside this little circle I think and that’s very sad. You still hear guys talking about AFD and Caswell and it bummes me out a bit.

Yes.

I tried 2k7 (I guess I got all the possible values pretty much ready to go by now....). It didnt really do any good. To boomy. The 3k3 sounds more right to me. I can do a clip if you want, but I think you'll come to the same conclusion.

Everything I do now seems to bring me away from what I want to hear.

I tried and take several pics of an Marshall JMP 76 with the #39 that i had back in 2013 in my bench, it sounded so good but after all it its a 76 JMP, the cathode caps were too small, good honky tone but not the AFD

I have tried a lot of times to make the 1n 470k work, but never did, it has the wrong mids for AFD

Yeah, it feels a bit like I’m fixing things that ain’t broken. There is still something though...... dunno, some woodyness....

What was the spec ?

1 stage like a 2203
2 stage same as 2203 but with .1 on 10k and 220k to ground
3 stage same as 2nd but .22 instead of .1

nothing special, people think they got the correct slash sound just because it sounds percusive and honky

Thank you for the info, that is the spec that started this all off lol, nice spec if you do it right. If you use the hot shield at the input and the shields coming from the pots going over the board it sounds pretty good, but most don't use the shield trick because they don't know how to do it right and fail with this spec.

What you have now is a good stable spec, you could try this, only if you want to.

2k7.68u 22n 470k500p 5n 150k or 220k from the middle lug of the pot to ground
2k7.68u 22n 470k470k500p
3k3.47u
820r
33k500p
100k .68u 4ohm

Its a lot of gain, so you might have to keep the gains about 4

That is going to squel quite a bit. Will require lots more shielded cable and more care to make it usable.

Well that's it, sometimes its best to leave alone and just have fun with what you have

Nah, I’m here to learn about amps and mods, so I’ll give it a go. I started with 2 2k7/.68 stages though and in my experience if you have bright cap on both (470k+470p/470k is same as a 1M pot with 470p bright cap at 8ish) it will squel at higher settings already. Then adding 3k3/.47 on third? Like, wow?
