2013 Ampeg V-4B 100W Reissue Pt2

So to expand on this question........(I haven't used a tube amp in a long time, so I hoping to get something clarified.) If you get the same power from the 8ohm, 4ohm or 2ohm tap, does this mean you will get the same volume from a single 8ohm speaker running out of the 8ohm tap, as you would from two 8ohm speakers running through the 4ohm tap?

No, more speakers equals more volume. This is assuming that all the speakers have the same sensitivity and the cabs perform the same. So two 8 ohms speakers in parallel connected to the 4 ohm tap will be louder.

The power tubes that were in this amp are a mix of 2 Sovteks, 2 Groove Tubes, 1 Ruby (with Egnator printed on it) and 1 Svetlana Winged C. It is highly unlikely this is a matched sextet. I ordered a matching set. So I am having trouble finding the bias information. Does anyone know the bias procedure for this amp?
@beans-on-toast

Which amp? You mention sextet so I'm assuming we aren't talking about the new V4B here...
 
My NV-215 has ears................. I have been fooling around today comparing these 3 stacks.

Kinda.

You wouldn't have any signal coming out of the amp unless you also connect it to the power amp in. At that point you might as well just plug in into the input.

@Dp1363 : Additionally, if you're unsure, try both setups, since the impedance differs for amp input / power amp in, as well as the tuner output may have a different impedance and level (buffered out) than your guitar output.

=> If anything sounds weird, even in bypass mode, try the other setup.

Same for volume pedals, by the way; no matter what they write, where it would belong; if something sounds odd, try using it in a different place in the signal chain.

Could that signal be enough to fry my tuner?

That's interesting! I never thought about that. Only know that people try out volume pedals (both types high and low impedance) in both places.

But to provide at least some clues, I have found this:
Invalid Link Removed

And on a German forum, I read a useful hint:
If your amp has a parallel fx loop (effects loop, meaning everything between preamp-out and power-amp-in), then a mix of the original input and the preamp-out => effects/tuner => power-amp-in is being played through the amp. That would mean, that when tuning the bass, it would still be audible, not muted.

If your amp has a serial fx loop (meaning if pedals are plugged in, only the signal from the effects are going to the power amp, not a mix of original input and effects), then the tuning would be normal; that is, it should be muted and work just like putting the tuner between bass and amp-input.

I also read that the different impedance (amp input vs. preamp-out) would not be a problem for tuning the bass. So both positions would be possible and practical.

But this is just what I read, I do not really know if there might be problems with specific amps and tuners. So, if unsure, rather stick to placing the tuner between bass and amp input - until someone who really knows provides an answer. Just posted this to provide at least some hints.

That makes sense. I was wondering if I can come from the pre amp out and not bother with going back into the power amp in.

I'll have to try it when I get home.

So, you've read through 158 pages of this thread (as I did), and you are on the cusp of buying a V-4B reissue (as I was). My advice is to just go and do it.

I've only been playing bass for just on a year (changed over from guitar) and I'm stoked to have found what I regard as the ultimate tone almost straight away. Bought a modest Fender Rumble 200 watt head and 115 V3 cabinet as my starting rig. Great tone. Just not loud enough, really, for our enthusiastic and rather heavy-handed drummer.

(Oh, I have a 2015 MIA P-Bass)

After about 4 months, last August I bought the V-4B head and another 115 cabinet and ran the head at 4 ohms. Great tone. Super happy and loud enough for my needs.

Couple of interesting things:

I took on-board everyone's advice and ran the V-4B with the master wide open. Ran the gain anywhere from about 9 to 11'oclock and that was loud enough and clean enough for my needs. Great, fat, round tone. Used a Bearfoot BBBD for grit and bit of drive - awesome and transparent drive that left the natural amp tone alone. How could things be any better ? Well.....

Firstly, recently I started backing off the master. Set the gain at noon and adjusted master to volume needs. Things just opened up. The EQ controls have a more dramatic effect on tone. It sounds more airy, lively, there's just the right amount of breakup that is touch sensitive. Don't need or want a drive pedal anymore. Sounded even more awesome. How could things be any better ? Well.....

I sprung for a 212AV cabinet a few weeks ago and turfed the 2 x 115V3 Rumble cabs. Holy f#$%balls. Whatever voodoo that the ampeg people have worked into this head/cab combo was immediately apparent.Played a couple of small open mics/gigs and random people were coming up complimenting how awesome the bass tone was and how it held the whole band sound together. Sounded phenomenal to me and obviously to others. Surely things cannot get better ?

Got to watch the band's bassist after us play through my rig with a Travis Bean (?) bass. Also ridiculously awesome.

Sorry for the long narrative. Thought this might help another fence-sitter (as I was).

Oh - and the volume question asked a million times ? Yup. In my loudest situations, with the master wide open, and the gain control at 11'oclock, it was just starting to break up but has still met/exceeded all my volume needs. With the gain at noon and the master around 11/noon as I run it now, it meets all my volume needs and has the greatest natural breakup that is so good, I don't WANT "clean".

I cannot imagine playing in a band/situation where I would need a 300w SVT. But that's just my personal circumstance.

Time to show my V-4B - love it so much :D

And time to thank all TBers who greatly shared advices, opinions, reviews and insights which I found very helpful. Especially @JimmyM and @Figjam whose setup encouraged me to even consider a 4x 210AV along with the V-4B - Thank you all very much! \m/

The setup looks a bit weird, since we use only 2x 210AVs for rehearsal - the bottom middle one and the top one. Loud enough to match the drums, and fewer but louder cabs lead to less bleed from the drums into the bass microphone.

For all who ponder whether to try 2x or even 4x 210AV - give it a try, if you like kind of a portal 810; with the ability to have each pair crossfiring to cope with room issues. The 210AVs are of course not the same like any of the 810, but sound- and tone-wise in the same club. If an 810 is your cup of tea, the sound of 210AVs may amuse you, too :D

 
You still using the four 210av rig?
No longer! It was great but I found a Peavey 215D that I like. Totally different tone, though. The 210s are really articulate and punchy. I kept one 210 and use it all the time for home practice (both guitar and bass). The 215 is at the space. I mostly play guitar now, but my partner uses the 215 for bass in our 2 piece drone metal outfit.
