I was wondering what kind of A/B/Y box you all would recommend that would allow me to run my Ghia and my Rivera at the same time?
My local music store sold me a Horizon Line Splitter which did the job, however the Rivera made a very loud buzzing noise when connected through this pedal. When plugged directly into the guitar, the Rivera sounded normal and was free of any buzzing.
That said, does any one have a solid recommendation for a pedal that would allow me to run both amps at the same time as well as one at a time without incurring any additional noise?
As always, thanks for the help-

I'm not familiar with that pedal, but if it's designed to do that it should have a ground lift to prevent ground loop noise. If it doesn't have a ground lift, discontinue using it right away. I'm doing the two amp thing with a Radial JX-2. It does the A/B/Y thing, has a drag control, an adjustable boost, and it's built rock solid. The down side is it requires a 15 volt transformer which can be a pain in the backside if you're building up a pedal board and everything else takes 9 volts. I also have a Voodoo Labs amp switcher here - haven't used it much, but it will do up to four amps, has the ground lift, and runs on 9 volts. I know the Framptone Amp Switcher ( www.robertkeeley.com/product.php?id=33) gets great reviews here by a few other guys - never seen one but Robert Keeley makes great products and several reliable folks here say it's the shiznit. Good luck!

Good luck! The two I'm the most familiar with are the Framptone and the Lehle. Both are great units. The Lehle units are harder to find in stores. Carl Verheyen was using one last I heard, if that means anything. Phil

I have used a Whirlwind ABY box for about 15 years with no problems.

Startouch makes a good ABY box for under $100. It's not super fancy with isolated buffers like the Framtone, Radial or Lehle but it gets the job done w/out any extra noise from what I could tell..

If you just want to run both amps simultaneously, you might consider using something like the Axess BS2. Just bear in mind that its not an A/B/Y device. Its a buffer with 3 outputs. Its handy at keeping levels clean, and there are lots of uses with a pedal board. Using a "Y" to split a guitar signal to two amps messes up the impedance which deteriorates the tone. A "Y" cable increases the possibility of ground loop hum (the loud buzzing mentioned in the original post). NOTE: One of the BS2 outputs is isolated from the others (to eliminate ground loop hum), and has a phase reversal switch, which can come in very handy. If one of the two amps you use is wired out of phase, the speakers of one amp will be going in the opposite direction of the other amp. The result is phase cancellation, which typically results in loss of bass frequencies (most obvious) and other frequency losses. To hear the effect, take your stereo speakers, reverse the wires on one of them, face them towards each other and the tone should drop off dramatically. I have no affiliation with the company, but I use one, and dig it. $150 for a pedal may seem like a lot, but if you've spent serious money for a Dr. Z amp, this device may help you get the most from it. www.axess-electronics.com/sc/BS2-Guitar-Audio-Buffer-Splitter-p-16133.htmlRadial and Keeley products are also high quality, and they may have an A/B/Y box that will suit your needs better than the BS2. Just be sure to look for something that has a phase reversal and hopefully isolated outputs. cheers, Dave
