if you don't want the guitar quieter than you need more juice.... time for an SVT if you must have tubes (I could care less about tube amps) or something that can push your 810 harder

Bass typically turned about 50%, mids at 90%, and highs around 30%, but this is off the top of my head. I am not around my amp to check. But I have adjusted the EQ to be best for our sound and for the most volume I can get. I turned to 50% bass per another person's suggestion on here and it helped a bit.
Buy an SVT head to go with the cab, Marshalls are the reason for their existence. A P bass would help also.
My bass is a PJ pickup configuration and I mostly turn up the P pickup. Do you still think that would change the volume if I had a regular P bass?
A friend of mine also recommended this, but I hadn't heard of doing that until then. Thanks!
I didn't mean the volume would go up, just that P basses are more punchy and audible than Jazzes, they have more presence, I have a P/J bass too. Back in the day when hard rock ruled the world if you wanted to be heard with Marshall amps, you bought an SVT with preferable two cabs (8x10 cabs) and used a P bass unless you put a single coil Tele or a Jazz pickup near the bridge as P/J's were not made back then, that started out with luthiers and people like us installing them and Fender finally caught on years later and started making them, to me a P/J with just the P pickup on is a P bass.

Are you using the ultra-low switch? If so, I recommend turning it off.
Also on your bass, I suggest turning one of the pickups down slightly to bring out more midrange.
The V4-B has the ultra-low switch, and I have the V4 which doesn't have it. But I turned back the bass a bit and it seemed to help a little. I'll try that with the pickups, thanks!
I didn't read the whole thread, but in case nobody mentioned it, depending on the size of the room, you could put all the power and speakers in the world and not get enough volume-- standing waves and various other acoustical phenomenon I don't understand clearly enough to explain will keep it down. It might sound completely different/louder in a big room. Just something to consider. 
Getting your guitarist a 212 cab would allow him to still crank the amp. ...but get less overall volume.
But. ..yeah an SVT is your best bet. As Beans..said...the V4 is VERY similar to the V4B. .so that's not the issue. I also doubt even IF your amp needs a little attention. ..that it would keep up against a Marshall thru a 412.
Adding another 810 will give you the most volume increase with your current amp.
But an SVT with one 810 should do it. Add another 810 AND an SVT and you REALLY got clout

I suggest unhooking the bottom two 12s in your guit players cab without him knowing.
HPF all the way. It will help keep your amp from wasting watts on trying to reproduce low freqs that add distortion but really can't be heard.
Try setting it about 60hz.
V4's don't really GET louder past where he's setting it. ..they just get more grindy. If ya like that. ..it's GREAT. . probly the best tube drive I've ever used/heard. But of you're after strong, solid bass.. need to keep the master or gain down a touch

Yeah, I thought about that as well, but it seems to be a recurring issue no matter where we are playing. Thanks for the thought!
I obviously tried turning it up, the problem is it doesn't get any louder. Thanks for the reply though!
Ampeg 810e sensitivity: 100 db
Marshall 1960A (Celestion G12T-75) sensitivity: 103 db
Marshall 1960AV (Celestion Vintage 30) sensitivity: 106 db
It takes twice the power to increase volume by 3db.
Depending on which cabinet your guitarist has, you need either 2x or 4x the amp power just to match his clean sound with your current cabinet. You may need double that power that to match his distorted sound.
If it is just additional low frequencies you want, you might consider adding a powered subwoofer. Then you could roll off the lows on your V4.

Get your V4 looked at to ensure it is running optimally. Put is up for sale and use the money from it, to buy a bigger amp. You hsould be able to find an SVT for close to the same price you will get for the V4 if you are patient.
