A '90's '63 RI Vibroverb was my gigging amp for my surf/punk band some years back. I only moved it on as I acquired a '90's Vibro King. I'm a sucker for the '90s Fender amps, even though they have their flaws. The Vibroverb's home volumes aren't great - it's wooly, muffled. Sounds like a heavy wool blanket is covering the amp. However, when cranked for gigs and rehearsals, it was amazing. I mainly used a Jazzmaster or Gretsch hollowbody during my gigging days. Both sounded great with the Vibroverb.
There are some mods out there that can resolve the wooly sound issue - Moyer Mod and/or Fromel Mod. I wasn't aware of the mods until after I moved the Vibroverb on. Eventually, I moved the Vibro-King on, too. Then acquired another one...only to move it on as well - cool amp but just too damn heavy @ 73 lbs.
A few years later, I bought a Fender "Custom" Vibrolux Reissue for pretty cheap. It's notorious for it's production flaws - diminished reverb output, hissing/humming. I got in touch with John Fromel and sent him the chassis for him to apply his Mod fixes. Once back home and back in it's cabinet - oh my, it was a fantastic amp. Fromel fixed all the production faults of this amp. As a huge fan of the brown faceplate aesthetic and hit with some nostalgia, I acquired another '63 RI Vibroverb.
This Vibroverb had the same wooliness at home volumes like my old one (even with different speakers). While I loved it's look, the Fromel Modded Vibrolux was the better amp. I wish I sent the Vibroverb off to either Fromel or had Big Crunch Amp Repair (closer to home) apply the Moyer or Fromel mods to improve the '63 RI Vibroverb, but I was on a vintage amp kick and preferred hand-wired amps. I moved on this '63 RI VIbroverb, too.
Eventually, due to needing to pay down gear debt, I moved on the Vibrolux as well - it was a great amp but I acquired a few vintage amps and a modern handwired Fender ('62 Princeton Chris Stapleton Edition), so the Vibrolux had to go.
I actually like the Fender Tone Master amps (I currently have a Tone Master Twin Reverb) that I use to play out now and again. I'd totally get a Tone Master Vibro-King or Vibroverb if Fender produces them. The Vibro King if they can halve the weight (90's VKs weigh 73 lbs) and the Vibroverb if the wooly sound issue is sorted.
It's crazy to see the '90s '63 RI Vibroverb going for about $2k on Reverb currently. I love 2x10 amps and someday hope to acquire an early '60s Fender Super. I kind of made my own in the meantime. I bought a '62 Fender Bandmaster head (housed in a non-original head shell) for $1800 and commissioned Armadillo Amps to build me a 2x10 combo cab (under $500) as the Bandmaster and Super have the same chassis measurements. For me, it was a totally worthwhile effort in having a handwired 2x10 vintage Fender amp.
I guess to sum up - some investment is recommended to make a '63 RI Vibroverb a great all-round amp - home/rehearsal/gigs (depending on your needs). Getting the amp modded is a worthwhile effort. If you prefer handwired amps over PCB amps, there are other options out there that may be worthwhile to you (boutique build, clone build, or something like what I did with the '62 Bandmaster).
Good luck!
