Here is a blast from the past, my ex drummer just sent this to me, it must be around 73 or 74. Yup, I really did have one back then see I wasn't just dreaming!

Totally agree with you. The ACC sound is not hi-fi. Look else where for that sound.ACC cabinets are more efficient. An original 361 Power Plus has a whopping 200 watts. That used to be a stadium filler. How many people think 500 watts is underpowered now? Lots of 'em. The sound is different, but it is a different tool for a different purpose. A 1000 watt amp through a less efficient cabinet might be more hi-fi, but it also might not. With an ACC stack, you have to know what you are getting and want that sound. I have been playing through ACC amps since I got a 126 combo (that I still have) when it was a few months old back in 1981. I know what they do and what they don't do. It works for me.

Describing sound is subjective, but the best way that I can say it, is , with ACC bass amps you hear the impact of the finger, or pick, clearer than any other amp, followed buy a dynamic, liquid, almost compressed sustain thats very warm for a solid state amp.
Case in point, check out an excellent example of what I mean:
Upon inspection it's loaded with EV Force 15's. Very similar specs to the originals, though they are a much heavier cast frame and magnet assembly. Should sound good with period correct gear.
Yeah! Try that setting with flat wounds and, boom! Nails that tone!
That looks very clean. I never use the boost or bright switches. I doubt you will miss them.I got a little more information from the seller on the 220/402 cabinet.
Everything on the head works aside from the bright and boost switches which I probably wouldn't use anyway and I got a video of it working. The db rating is around 100db. Is that not loud enough for a band?
Here's the listing. Planning to meet him tomorrow.

I don't want to boar people by repeating myself, but, I cant imagine a 220 not being loud enough, unless you're playing large venues or outdoors arenas, and thats what P.A.s are for.
In my current band I play with a powerful rock drummer, and the guitarist uses a Mesa Boogie duel Rectifier.
My 120 does just fine.![]()
Congrats on the acquisition of that fine amp and cab. You'll get some classic tones running that Precision through it. If you ask on here you might find a source for the missing slider.View attachment 4612168
I found a different 220/402 with the original speakers and no issues with the head from the original owner. Even have the receipt from Sam Ash in 1980. This thing thumps! It's a bit larger then I had anticipated but I'm liking it so far! Totally different tone than the 1974 Traynor 20 watter which is dwarfed next to it making it perfect for re-amping DI bass in my studio. Believe it or not the owner even had a second 402 cab. I could only imagine how loud that rig could get.
Thanks to all for the info!
One other question… Did ACC make a 1x15 speaker by any chance or was the 402 the smallest cab back then? I'm just thinking if this 2x15 is too much to lug I might need to swap the cab.

Totally get that! This rig will live in my studio so it's not moving much but if I had to lug it to gigs I'd have a very different rig.Funny how what goes around, comes around.
I use to use an Ampeg B-15 and then an Acoustic 126 combo amps but give up on them because everyone I was playing with, played too loud for them to be used. So I got all those big cabs and amps.
Now all of that kinda stuff is too big and loud for what I get to do now. So it's down to this now...

If I still had the 126, I'd be using that.Totally get that! This rig will live in my studio so it's not moving much but if I had to lug it to gigs I'd have a very different rig.
That Mesa / Aguilar setup is amazing.
