It sounds like you are struggling with this bass amp/guitar amp quandary.
You seem to act like it's a new concept, or that there is something incompatible about bass amps and guitars.
Ed -
No, I'm not "struggling" with the concept. I fully understand that you can plug virtually any guitar into virtually any amp ("guitar", "bass", keyboard, pa, or otherwise) and get sound out of it. Are they all going to sound the same? No.
I still don't think you get it (i.e.; "struggling"). If you are talking about Sunn amps, other that the intrinsic differences between ANY hand wired tube amps, the answer is YES. Other than boost switches (which you can always turn off), and minimal tone knob "center" variances, the majority of the old Sunn bass
and guitar amps share
identical circuits. The parts; chassis, transformers, filters, tubes, etc. are the
same.
Speaker cabs are another thing altogether, but you didn't mention those in your posts.
Are they all going to sound good? Definitely not.
I would say that that is a matter of personal taste, an opinion, certainly NOT a "Definitely not"
I also understand that many musicians have used different Marshall, Fender, Ampeg, Orange, Hiwatt or whatever "bass" amps as "guitar" amps but I'm not concerned with that.
The point I was making is that they were NOT different amps, they were the SAME amps that were used for whatever instrument the musician happened to play.
Since, I'm a guitar player and not an electrical engineer pointing me to some schematics that I can't read isn't going to help me find the answer to my question. If I knew how to read the schematics I probably wouldn't need anyone's advice in the first place.
I just thought you might notice that they are all THE SAME FREEKING DRAWING!
So before you reply to anyone else's posts try coming down off of the pedistal you've built for yourself out of vintage Sunn stacks and try using your knowledge to provide some USEFUL information.
I reply to lots of posts, lots of times
just to share information I've gathered from up here on my pedestal with obvious neophytes like yourself. I normally stay away from in depth electrical discussions, keep more to theory rather than express my opinions on specific component values, or "personal taste" circuit mods, because I would rather help to "keep the flame alive" for vintage gear with those just getting into it.
I'd like to think that I've helped out a few people along the way.
I think I DID give you useful information. It was
your choice to be obtuse about it, and spew venom rather than pay attention and futher your knowledge about Sunn gear.
