Running Three SVT's w/Three 8x10 cabs together

#22
There are a couple of ways to try to hook them up.

Diasy chain the inputs. Plug into the normal input of the left CL. Run an instrument cable from the -15dB input to the normal channel of the middle amp. Then repeat, run another instrument cable from the middle amp to the next one. With this setup, you use the three amps independently.

Next option. Connect an instrument cable from the slave out of the first amp to the power amp in of the second amp. This will allow one preamp to control two power amps. You can only connect two amps this way. You could try a Y splitter at the slave out to feed the power amp in of the other two amps. It’s possible that this might load the slave out too much. Otherwise daisy chain from the first amps’s input to the third amp. This would use two preamps though.

If these approaches fail to drive three amps at once, try a buffer pedal, instrument in, three outputs, one to each amp.

No, local SE Michigan act in the late 70's early 80's. Guitarist had two Hiwatt 50 heads with 4x12 cabs, Fender Twin, and an Ampeg VT22 w V4 (4x12) cab. Sometimes they would all be up. Although I liked the SVT rig it wasn't clean enough for the tone I was going for so I used a PA System - upwards of 4 18" and 4 2x15" ProCo Sound Cabs (TL606 derived), some EV horns - a couple of racks of Crown DC300's, DC150 for the horns, crossover, and driven by an Ampeg B25 head (modified). - it would control your heart beat if you walked in front of it. The nice thing was it that it would scale - tight club stage one 2x15, etc and I could use the rest of my cabs in my PA rental business.

If I were you I'd get rid of SS middle one, use the two matched SVT's, two is more than plenty and sounds great on any sized stage, I've used one head and two cabs before on very big stages at a Civic Center and it sounded great, (my one huge gig). Plug your bass into amp number one, then run the preamp out to the power amp in on amp 2, that's as far as I've gone, amp number one's preamp (tone's, volume etc) will control both amps that way, if you really want to use the SS amp for a third amp I think you might need a splitter to split the signal from the preamp out on amp number 1 run to both power amps on both amps number 2 and number 3. I really don't think the SS amp will add much though except for looks.

One svt will run 2 810 cabs
And I would realistically start there

When playing on the road I didn't really have enough room on the trailer to add a third cab. Wanted too, but couldnt

Already had 2nd amp to run it. But likewise had reliability issues with both heads.

If you successfully haul around 3 svt heads and dont end up broke and hairless with break downs and tech cost. More power too you.

One head running 2 cabs is definitely a glorious sound and lots overhead.

Use the preamp out of one head this signal is post master volume. Then plug into power amp input of the other amp.

Using the power amp input disconnects the preamp of that head and the tone controls and master volume will control the second head as well essentially just making it a slave power amp

I agree with everything you said except I have found SVT's to be VERY reliable with minimal upkeep.
