2013 Ampeg V-4B 100W Reissue Pt2

Can't comment on the 112AV, but the 212AV has made me a total convert. I have owned GK and Bergantino twelvers before and neither did it for me. I had pretty well given up on twelves before I bought my 212AV. It is tight, punchy and controlled across the frequency spectrum. Loves tube amps too. Currently I have mine in the lounge for practice as it just sounds so good. Each week I put a different head on top of it, and with each head it sounds great but also responds to the head's character sound. Bottom end is so tight it reminds me more of a sealed cab than ported. Some sort of magic in it, I reckon. If I didn't have too many cabs already I would buy a second for bigger gigs. For someone starting out you could buy a single 212AV for small to medium gigs and if you really wanted to rock out big time add a second 212AV later. That would do any gig. Good price, not too big a footprint and very manageable. I would imagine the same applies to the 112AV although my preference would definitely be the 212AV.

Ya, that one sticking out is V1. I forget how they break down for jobs. Beans will know.

Try a new Tung Sol in there if you want a really bright V4B, BTW. Me, I did a little tube rolling and stuck to the JJ's.

OK thanks. I've had visitors drop in today so no dice on the trying out various tubes today. I did put an old 70s Raytheon 5751 in that V1 spot. Si that'll be try out no.1.
 
I just pulled the trigger on one of these after four dry fires. I bought myself a 212av for Christmas and have been pretty stoked with how it pairs with my svt 3 pro with the intent of adding this head. After creeping on this thread for a long time I'm glad to say I have one in route. I'll probably roll the 3 pro to lessen the cost but I'll wait and see.
 
Looking at the amp from front on (front grille off ) can anyone tell me what pre tubes are what?
I'm assuming V1 pre tube-closest to the input jacks - is for gain. ..?

I'm gonna try a few different tubes in the pre amp, just for kicks.
Any suggestions or experiences?

The link below should help Rod. A low noise tube is good for the input. A triode matched tube for the phase inverter wouldn't hurt but isn't necessary. That takes care of noise levels. Other tubes will have subtle tonal effects. All I can say is try all you can and see.

V1 and V2 selections will help optimize tone.

OK, technically this is a cab question, but since lots of folks seem to be pairing up the 112AV cabs with the V-4B, I figured I'd give this a shot first...

I recently acquired one of these V-4B along with 2 of the 112AV cabs (and recently a PF-500 as a backup) and I frikkin' love it. Some of the places we will be playing will have tiny stages, so I'm thinking about investigating the possibility of 'going vertical' with the cabs. I've seen JimmyM's pics of the various arrangements, including the ill-fated 'T' setup and was thinking of stacking the cabs and using the PF-500. My question/concern is regarding the stability of the cabs since there are no feet on the sides. Yes, I supposed I could buy feet and use wood screws to mount them, but I'm wondering if anyone has any little tricks to help with stability. I was thinking of maybe cutting a square or 2 out of a thick Yoga mat (or even wod) between the cabs or something along those lines....
 
They sell packs of interlocking floor mats at hardware stores that I use under amps or between cabs. Easy to cut it to size with a ruler and a razor knife. The material is a spongy rubber, same as flip flops.

I stack cabs but don't always feel the need to place the amp on top of them. It works well on the floor.

Thanks. I'll look into one of those mats. The cabs obviously won't stack on top of the V-4B and so if I have to stack, there won't be floor room, so the PF-500 would go on top.

Thanx Beans. Appreciate that and the link.

OK. I finally got a chance to try a few different tubes in the V1 pos of my V4B RI. I only had time to try 3.
The original JJ, a NOS Raytheon AX7 & JAN Phillips 5751.
The original JJ was fine. No probs and sounds cool.
The Raytheon AX7 - a li'l warmer with a darker overdrive.
The 5751 (again) was my fave. Warmer still and gave a li'l more headroom before breaking up. Which is what I'm after with this amp.
Still had a nice warm overdrive, but gave me more room before that OD hit.
It's staying in there for now.
 
I almost took one of these home today, but I got cold feet with my trade-in and decided to wait. The tone on this amp is phenomenal! It's warm and rich, and it's the tone I hear in my head when I think of bass. I thought I loved the tone of my PF800, but the V4B is apt more complex. I may go back in a couple of days and take the plunge, now that I think about it. I Have no doubt that it will fill all of my gigging needs, volume-wise, and I'd be willing to live with the weight compared to my PF800. Decisions, decisions.
