So.... can anybody comment on what this will sound like compared to the power amp from a B-15R?

2013 Ampeg V-4B 100W Reissue

Looks like this will be my next amp. I can't wait to hear some reviews on this amp and some comparisons between the V4B and 100T. I've got a lot of overtime coming up soon so I should be able to pick one up a couple months after they start shipping.
Is there any place i can buy a vintage style grill all ready to go for my svt410he?? if not how would i go about putting a new one on?
my head is a 1972 v4b

1/4" connectors is not the only possible option, though. EBS, Trace Elliot and Ashdown are examples of manufacturers that have Speakons even on their low power tube amp models.
www.fliptops.net and Ampeg is going to start selling them soon as well, though not sure when. But they're working on it.
So, what happens when somebody plugs an 8 ohm cab into the hole marked 8 ohms and plugs a 4 ohm cab into one of the holes marked 4 ohms, at the same time?
Well say you wanted to run 2 cabs...(1) 8 ohm and (1) 4 ohm. I know what you get when you daisy chain them together but I think it's a good question since there's not a 2.67 speaker out.
I would run two 8 ohm or two 4 ohm cabs only. Got no interest in trying to make mismatched cabs match 
But I will agree that it's a pretty good question since I know someone will try it. I don't know how the new jacks are wired, so someone from Ampeg directly will have to field that one. All I know is I would never try it just because of the jury-rigging aspect.

Is the v4 bh same preamp as the svt classic ? I noticed the vr has 12 au7 and 12 ax7 tubes in preamp section .
That doesn't mean they're the same preamp. Pretty much all tube preamps these days use 12AX7's and 12AU7's, and the ones that don't are rare. The Jule Monique is the only commercially available pre I've seen these days that doesn't. I don't know much about the V4BH, but just by virtue of the 5-way mid selector on the SVT-CL as opposed to the 3-way on the V4BH, they're not the same pres.

I wouldn't do it. But, it seems to me that the way they've done the back panel, with 5 output jacks, it's just begging for someone to say "I've got 2 4 ohm cabs and an 8 ohm cab. I'm going to plug in all 3 so I can get really loud!"
It definitely seems counterintuitive to expect somebody with 2 4 ohm cabs to look at the back and go "I see. I'll plug these into the 2 jacks labeled 2 ohm." There are a LOT of posts right here in this forum from people who need help figuring out how to set the impedance selector switch when they plug in 2 4 ohm cabs. I bet a lot of those people will just see 2 jacks labeled 4 ohm and they'll plug both cabs into those.
Actually a lot of companies seem use this instead of a switching system these days. Mesa, Orange, [DEL]Traynor[/DEL], etc. I guess it's one less part to fail, less error on that front, at least. I would hope someone buying one of these amps would take the time to read the manual.
Good question. From what I've heard, those SVT-100's were pretty good bass amps. But they were slightly modded V5's, which weren't real well received for guitar, whereas a lot of folks loved the V4 for guitar. So that makes me think they've got to be pretty different.
Assuming you don't mind each cab getting the same power, plug the 8 ohm cab into one of the 4 ohm jacks and the 4 ohm cab into one of the 2 ohm cab. The 8 ohm cab presents a 1/2 load on the 4 ohm jack and the 4 ohm cab presents a 1/2 load on the 2 ohm jack. Last I knew 1/2 + 1/2 = 1
. OTOH if you want the 4 ohm cab to get twice the power as the 8 ohm cab I'd use the two 2 ohm jacks - 2.66 ohms is close enough to 2 ohms IMO. Many folks run an 8 ohm cab on the SVT's 4 ohm tap. I used to run a 4 ohm 2x15 on my side of the drummer and an 8 ohm 1x15 on the other side so can understand someone needing to do what you propose.- Status
