For what I see from the pics, it's a '74 so it already has a master volume.If you decide to get the Twin and want to run it at lower volume, you can pull the outer 2 output tubes out and disconnect one speaker to match up the lower output. Or, get a tech to install a master volume.
I believe master volume in those Silverface Twins are a very useful feature. Some people dislike it, to me it's the only way you could use a Twin not only at home but also in live situations in these days. There's no way a sound guy in any club/bar would let you use your Twin at 4/5 volume where it should stay to have the best tone.Doh, I didn't see that
Just consider that the Twin is about 70 pounds, a real burger to move around. I replaced mine with the later Vibrolux, with the moyer mods, and I could not be happier.The Twin is way better than any of the new faux junk. It’s built better, cheaper to fix, will sound waaaay better and hold its value.
I won’t slag on Marshalls, but they aren’t for everybody. I like Twins, but they really are for playing larger venues. I’ve used mine for outdoor gigs, and it really comes into its own in that setting. BTW, mine has a single 15” with a closed back, piggyback, cabinet. But a Twin, likewise, is not for everybody.I’ve played through lots of amps over the years and it really comes down to personal preference. Marshall is bright, loud and minimal bass, twin is loud but I don’t find anything alluring over its way it sounds, the hot rod fenders were ok, a bit wooly sounding I put down to the cabinets.
I love little amps because you can push them hard and they bark back. Vox AC 30’s have a really creamy sound and on stage they cut without being rude. I just bought a Vox AC15HW and have to say, I’m impressed. I’ve only got one gripe with it and that’s due to the modern features that make it sound too fuzzy when pushed, but I intend to carry out some mods to fix that issue.
FWIW, I’ve got a black face vibroverb with the 15” Altec Lansing speaker.
For a while, I used to hire it out and one particular guitarist, won’t name him, he was awesome player but loud as. It came back with a dead speaker. I didn’t want to recone it for fear it’d lose its sweet tone so I meticulously disassembled it and found the voice coil had come off the braid. I resoldered it, piled epoxy over it and since then has never left me. It’s the best sounding amp I’ve owned. The only mod it’s had is a fan to keep it cool while I was in the tropics.
I recently pulled it out of storage and overhauled it, changed filter caps with F&T, bypass caps with orange drops and some resistors that had drifted in value too far. It’s just a beautiful sounding amp and it’s going nowhere!
they didn’t make that many of them. less than 1000, but can’t recall the exact number. was my holy grail amp for decades.But that 1x15 Vibroverb is a gem. Probably close to the headroom of a Twin and maybe a bit less in your face. It’s surprising to me that these are not more common.
They were only made between 1963/64, discontinued when CBS took over and so there weren't many made, especially with the grey basket James B Lansing 15" speaker also known as Altec Lansing which later became JBLthey didn’t make that many of them. less than 1000, but can’t recall the exact number. was my holy grail amp for decades.
