wedgeSG Posted February 21, 2010 Share Posted February 21, 2010 OK, maybe this is a stupid question but I think theres a couple of folks out here doin' this someway: so what's the best way to go about it? I know that you can take a pair of 8 ohm cabs and with a mono Y-adapter run 'em into a 4 ohm tap: but can you split the signal off of the guitar cable with a Y-adapter and feed imput into a pair of heads? Will this work or is the instrument signal too weak? Can the heads be adjusted independantly or do they need to be at about the same volume? (Valve Juniors) In a nutshell, I've got a modded Vers.2 running a 2x12 at 8 ohms and a stock Vers.3 I'm running a pair of Y'ed together 8 ohm cabs into a 4 ohm jack. Just outta nut job curiousity I'm wondering how this would sound if I combined it all together...somehow... of if it was possible...or if it was the result of tooo much vodka. I got the Vers.3 setup recently as more spousal friendly alternative than the modded Vers2. and then the cogs began to turn... So to any of you multiple head players that can clue me in on this I would be most appreciative, wife might not be so greatful however.

m-theory Posted February 21, 2010 Share Posted February 21, 2010 can you split the signal off of the guitar cable with a Y-adapter and feed imput into a pair of heads? Sure, if you want one amp to have much better signal than the other, and if you like ground loop hum. The correct way to do this is thru a buffer with isolated outputs, such as if you were taking both outputs from a stereo effect. Otherwise, neither amp is getting full signal, and you're liable to have serious ground loop hum. This assumes that you're running a seperate cab for each head.

bluesman345 Posted February 21, 2010 Share Posted February 21, 2010 I don't know, but it sure sounds like fun! Link to comment Share on other sites More sharing options...
wedgeSG Posted February 22, 2010 Author Share Posted February 22, 2010 I'm hoping to boost the fun level...so could we talk a bit about what to use as the buffer with isolated outputs? Is this a easilly obtained component, or something sourced from other equipment, or something that will have to be fabricated? I'd love to give this a whirl just for my own inquiring mind; but if it's a silly endeavor maybe I oughta just let it go... I kinda figured that there was more involved than just splitting the guitar signal - but am I incorrect in assuming that this could be accomplished and a possible upgrade as well?

A buffered A/B/Y switch will do it, as will a stereo effect, such as a delay or chorus with stereo outs. http://www.aronnelson.com/gallery/main.php/v/zpyders-veb/zpyders-perf-layouts/humfreeaby/Improved_Hum_Free_ABY_Perf.gif.html http://www.tonebone.com/re-bigshot-aby-detail.htm Link to comment Share on other sites More sharing options...
