3 amplifiers makes it more complex because they simply don't make stomp switches which will scroll between three connections. I run stereo amps in my studio and I'm able to swap between them fairly easily because switches toggle between two states.

I suppose a loop box could be incorporated but I'd really need to study your gear and know all the possible connection options. Typically loop boxes are used for adding an removing pedals. You'd likely want to buffer the signal as well which may be good or bad depending on your situation. The cost isn't that expensive and you can actually save on the cost of the switches. You can do this using simple triggered gate/latch circuitry.

If one amps on and two are off - you press all switches and you have two on and one off. If you use three switches you can select any or all to be on. you could wire one switch A/B/Y and the second simply on/off but that would leave one amp dominant. You can mount them close enough together where you can activate multiple switches at the same time with a shoe if you choose. If you want to switch between three amps using passive switches then using two or three stomp switches may wind up being the cheapest solution. They weren't all that durable and its likely cheaper to do it using transistorized switching and a single momentary switch. Unfortunately I haven't been able to find those kinds of switches in ages. Years back they did make some push button switches which were dual action you pushed it once and you had one connection, push it twice you had a second connection and the third time it would shut off.įor a single stomp switch to toggle between three amps you'd need that kind of triple action switch. You can have single, double, triple and quadruped throw switches but the are all on an off. The fix is having all amps on the same outlet to avoid having AC flow from one chassis to another.Īs far as having an A/B/C box, most foot switches are on/off type. When one does exist your solution doesn't fix the problem, it simply masks it. I've used all kinds of A/B boxes and the only time there is hum is when a ground loop exists. Without transformer isolated outputs you will run into hum problems under the wrong circumstances.You're suggesting there will be a problem before it even exists. I use the Radial Shotgun and the Palmer splitters - these are not footswitchable, but have little switches. LED indication, quick clip battery door and one-year warranty.To split a guitar signal i recommend something with transformer isolated outputs.Powered by one-9v battery or optional Morley 9v adapter.High Frequency Filter activates when Ground Lift is engaged to eliminate unwanted frequencies.Ground Lift switch to combat hum from ground loops.Reverse polarity switch to prevent phasing issues.Silent Relay Switching to prevent pops and bleed.Easy accessible rugged cold-rolled steel enclosure 6.63″ x 4.38″ x 2.75″ (L x W x H).Custom Morley 1:1 isolation transformer for absolute transparency and level output.Choose A, B, or C individually or in any combo.

You WILL damage your amp, speakers or both! PLEASE NOTE! DO NOT use on powered speaker lines. New features include a higher enclosure for easy access, a custom built Morley 1:1 isolation transformer, silent switching, a reverse polarity switch and a ground lift switch.
