How Could I Increase the Volume of my Setup?

I have a '72 Ampeg V4 amp (non-bass), and a modern Ampeg 810e cabinet (probably early 2000s?), and I play an '86 MIJ Jazz Bass Special through the rig with nothing but a cable between the bass and amp head. My band's g*****rist plays through a ~2000 Marshall JCM Slash Signature half stack, at 50W (100W capable), and is turned up to typically about 8 (when his rig is turned up to 100W even on 2-3 it drowns out my setup). My rig typically cannot compete with his, and I was hoping to get suggestions for increasing the volume of my setup. Should I splurge and get a 2x15 additional cab with a slave amp (to keep the tone of the tubes from my main amp), or do you think that this situation doesn't seem typical and that I should service my amp to see if there may be a problem with it? Or do you think that replacing the pickups on the bass may be enough to increase the volume? Or is there another method that I haven't considered that you could recommend? Thanks in advance!
I dunno. But for God's sake, change that font. Are you on an old Unix mainframe?

(just harassing you in good faith, no need to change anything :D )

Buy an SVT head to go with the cab, Marshalls are the reason for their existence:roflmao:. A P bass would help also.

Thanks for the input! I was afraid of that, and in buying the V4 I obviously had doubts since it's not a "bass amp" but so many people on the internet swore that it was just as good as a V4-B that I gave it a shot.

I had a V4-B years ago, those won't keep up with a Marshall 50 watt head either, 100 watts just isn't enough for a loud guitar.

Never play in bands where the guitar uses a Marshall 4x12 sealed cab. Those things are low mid monsters ...

2 things happen if you play in a band with a guitarist playing through a Marshall 4x12 ...

1 - you get hearing loss
2 - the bass gets drowned out.
 
the non-bass amp speaker cones are not meant to reproduce bass frequencies and the speaker excurison (cone movement ) is not the same as a bass speaker cone....get rid of the guitar rig and get a bass rig...a preamp can bring up the volume of your amp...and using a compressor with little or no compression being used..but the gain knob turned up...will increase your volume...
Pretty sure he has a bass 8x10 speaker and a guitar V4 amp
 
. The last time I saw mike he was playing a 35 watt Mesa with 1x12. Guess he learned is lesson.
Get the amp checked out.

I gig with not much more power than that. A V4 should be devastatingly loud through a big cab.

If you're scooping your mids, stop doing that. Boost them instead. And if your V4 has a gain knob, dime it.
I suggest dime the volume and control your it with the gain. Per @agedhorse

I'm 64 and played a lot when Marshall amps were just about the only thing guitar players used (70's) and a V4 or V4-B no matter what you are using for a cab will just not keep up with a Marshall if the guy plays it loud and they are supposed to be played loud, some of you guys must be playing cocktail music:roflmao:. I owned a V4-B back in the day and while it was a nice head and sounded pretty good it absolutely did not have enough oomph to keep up with a Marshall amp in fact most guys who played in bands with them used an SVT head with either two SVT cabs (8x10) or two V4-B cabs or both. I used to use my V4-b only for rehearsal. One more thing that head is only going to put out 100 watts no matter how you got the gain or the master volume set, it will just get more dirty sounding, the cleanest and hence the loudest way is to set the master (power amp volume) on 10 and use the gain (preamp volume) as the volume control, that is exactly the way a non-master amp works, they have no master the power amp is up all the way and the volume is controlled by the volume control (gain).

I've seen a bassist play doom metal through a V4 and 810 (well, also a 610). It was bonecrushingly loud.
 
Well all I can say is that you idea of loud must be different than mine. An SVT head with two 8x10 cabs is loud to me.
SVTs are common at shows I go to. You can't crank them, even in doom though, in a small room. Otherwise it'll drown out the drums and the vocals. A V4 you can.

Of course, this is if you don't care about clean. Which I don't, and most people who play doom also don't.
 
Yeah, fair enough that the guitarist is that loud and you can't be heard, but can the singer and drummer be heard?

Don't turn up, turn him down.

Exactly. When we practice we play to the PA. That means if the singer needs the PA turned up because he/she can't hear themself, the rest of the band is too loud. In a typical garage/basement practice space you can't get the PA but so loud before feedback becomes an issue. Even with EQ and something like a Behringer Feedback Destroyer (we have), at some point you'll never get the PA loud enough. At that point I look over at Gary (JCM 900) and tell him to turn down. He argues but he does turn down.
 
A lot of tube guitar heads, especially marshalls, sound like crap with the volume below 6 or so. I would keep him on the 50w mode, but I wouldnt expect it to sound great if he turns down much. It isnt unreasonable to want to play guitar through a 50w head and have it turned past halfway. Thats really where those heads come alive, and they sound brittle before it.

Your 100w tube head is not enough. V4s are great heads but unless you are running a stereo rig with another head, it probably will struggle. They can compete with 20w tube heads but not 50+.

I would sell it to a guitarist (guitarists love those) for $700 and grab something else. Maybe a traynor 200w or 300w, or a peavey 300w. If you miss some of that ampeg bite, grab a tech 21 VT bass pedal.

We run a Sunn Concert Bass (a conservative 200w) with a VT bass pedal into an efficient peavey 215D. Keeps up with a marshall 50w head run stereo with a marshall 100w head. All tube.

If I decide to ditch tubes this looks promising! Thanks!

The SVT pro line is really nice, too. I like the 6 pro, but it is an odd duck since it is discontinued. Same preamp section as the big SVT with an 1100 watt solid state power amp. It sounds darn close to the real deal.

The 4 pro is a more popular choice and offers different features, they're also pretty really available.

I think it's worth mentioning that a Gallien Krueger head would sound AWESOME through that cabinet. You have a lot of options!

Invest in yourself.
You need a different rig and maybe a different bass. I know you don't wanna hear that but "the tone" can be had in different amps and/or cabs. Explore the options available. You don't have to go with what's popular. Check out the Mesa m9 and the 400+, the Aguilar db751 (my suggestion with the Aguilar 4x12), the Gk 1001 and etc... Yeah it will cost you a lot more bread but it'll be worth the sacrifice. Don't be penny wise and pound foolish. You'll thank yourself later.

Don't do "just enough" to get by.
