So I recorded this comparison between my friend's 79ish 2204 and my 76 1959 with a newly installed PPIMV, plus new power tubes.
I have a question or two but I'll kinda explain the rigs first.
The 2204 is on a JCM800 cab with G12-65's in it. The 1959 is on a JCM800 cab with a mid 70's G12M-25 mic'd. For the A/B I'm using the exact same SM57 then I use two and play them both panned hard left and right. The A/B section of the clip is coming from a looper in front of the amps. 2204 first then the 1959 then both. I'm using a little analog delay in front as well and that's it. I didn't get levels perfect but I think it's good enough to demonstrate some major differences.
My question is why does the 2204 sound smoother, or less sizzly, biting, or even harsh, etc? They're both great. I think of the 1959 as early AC/DC and the 2204 closer to the Back in Black stuff maybe, though I can't say for sure what amps were used there. I prefer the 2204.
The problem is it isn't my amp. But the 1959 is. So I'm thinking of how to get closer to that with easily reversible mods. It sounded pretty much the same before the master volume but louder is all. Sounds the same on other cabs, even the opposite 4x12. I'm not sure that it's a bright cap thing or even a gain thing. I've considered getting the Mr. Scary Hot Mod but I'm not sure it'll change this beyond adding gain. Gonna try some different preamp tubes and go from there but any advice is appreciated.
