Members kiriako Posted February 22, 2015 Members Share Posted February 22, 2015 I want to run two tube amps, either A/B or together... BUT I don't want to run my effects loop out of just one amp, and only use the power section of the second amp. Im looking for an ABY but, one that takes my signal, splits it and runs it into the front of the amps, then takes the effects sends from both, then run that through my pedal board, and send it back to both amps. ...And to complicate it even more, would it be possible to take a stereo return from my pedal board into the ABY and run either a mono signal to A or B amp, or back to stereo for when you run both?

Members DeepEnd Posted February 24, 2015 Members Share Posted February 24, 2015 It might be possible if you were willing to put a pedal board before the ABY box and skip using the effects loops on the amps. That's all I got. Link to comment Share on other sites More sharing options...

Members WRGKMC Posted February 24, 2015 Members Share Posted February 24, 2015 It can be done but not with normal switches. There are too many contacts that need to be switched over. You have your input cord, then 4 additional cables that need to be switched. That would require a 5PDT switch which they don't even make. You may be able to use one of these slider types but they really aren't foot switches. These are commonly used in tape recorders to switch multiple contacts but they are fragile and do tend to be noisy. http://www.mouser.com/ProductDetail/E-Switch/PBH6UEENAG1DBLK/?qs=5gBG3L055oMqdm%2fJb0mXhA%3d%3d You have two other options. Using electromagnet switching using a ganged reed switch. In essence you use the switch to kick on electro magnet that closes multiple reed switch contacts. The electromagnet would activate with the switch closing supplying DC voltage to the coil. Ypou could do the job with 5 of these. http://www.alliedelec.com/omron-electronic-components-g5v-1-dc5/70175801/?mkwid=7OJ0FAlB&pcrid=30980760979&gclid=COiUhKmy-8MCFQiHaQodMnoAMw a power supply and a single SPST switch. You mount the relays on a PCB, connect them properly to your jacks, add the power supply wiring and connect the spst switch to apply and remove the power to the relays. You can even find multi ganged relays of different types. This one uses a DPDT which would probably be better because you want to swap the wires in pairs. You could use two of these for the effects loops and one of the others for the guitar cord. (or jet get three of these and have an extra switch available. You can also do this with solid state relays. They essentially work like a mechanical relay does but are solid state. These are commonly used for controlling AC devices with a low DC voltage. I'm just not real sure which might conduct an audio signal well. The ones I'm used to using are fir turning on electronic gear and supplying power. Vever tried one to pass an audio signal and don't know if the device might have internal resistance or produce noise. This one looks to have .12 ohms which is fairly high when you consider a guitar signal is less then 1 volt. http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_991220_-1 The last option is to use electronic switching. You would need to use chips like these to do the switching or find something premade that will do the same job.http://www.globalspec.com/learnmore/electrical_electronic_components/switches/signal_switches I would figure finding something premade would be better, in fact you could even go wireless with the switch.
