heres my rig:
left side - marshall JMP - a/b box to switch channels.
right side - peavey 5150 - using provided channel switch box.

using a stereo delay for optimum depth and fullness.

heres my problem: i need a way to simultaneously switch channels on both amps. yes, i could use a distortion pedal before the signal splits and save a shit ton of trouble, but i dont want to. i want to be difficult.

so yeah, is there a way i can make one switch that switches channels on both amps?

i know thats some scarce information to go on, but any help is, as always, appreciated. redmedicine77 on AIM if you feel like asking for more info or yelling at me or making dinner plans.

joke.

yes, this is easy. I don't know the switching for the 5150, but if it's just a standard on/off switch, this is easy. You can build it into your existing AB box.

1. get a DPDT (double pole double throw) Stomp switch. this is a single mechanical switch that has two independent two-way electrical switches. In other terms, a DPDT is two SPDT (simgle pole, double throw) switches that swtich with the same mechanical device. make sure this fits into your A/B box.

2. Drill another hole on your A/B box and install a 1/4" input jack for the Peavey channel switcher.

3. your A/B box uses a SPDT switch. Wire up one of the SPDT circuits just like your A/B box. Wire up the center and one of the outside connections of the other SPDT circuit to the hot and ground of the new 1/4" jack.

Now, when you step on this one switch your A/B box will work, and you'll change channels on your amp. Cost is about $20 in parts for good quality stuff and a half hour of work if you're good at drilling and soldering.

If the 5150 has a specialized footswitch, I'm sure a tech can do this for you, but it'll cost more and might be a bit more complex.

okay i got my A/B box open in front of me. the existing switches have _six_ connections on them. i have one of those morley boxes that have the option of A OR B or A AND B... theres not a whole lot of room for mods, but i could maybe find another box but - can i use the existing switches? are they already DPDT? i assume they are to replace the existing switches. and im assuming they arent DPDT because all the connections are being used already.

i dunno im a beginner at this, but i really wanna get into it.

also - the switch box on the 5150 has a 1/4" trs connection i guess tip is for channel switching and the ring is for effects loop (which i am not using). any clue if this is true? (what do i do? what about you? i might have the flu. scooby dooby doo)

thanks for your help.

ill try to illustrate: existing switches look like this:

ignore the periods.
thanks again - wiggins

***oh yeah!***

-the 1/4" connections on the box are also TRS plugs. will this idea work with a simple splitter?

While the morely ABY is a slightly more complicated circuit, it's still pretty simple. It does have DPDT switches, but one half is sed for audio switching and the other half is used to switch the LEDs on and off. However, it does use circuit boards, and the jacks are soldered directly to the curcuit board, so it'll be a bit more of a challenge to mod.

Here's my advice. Sell the Morley ABY for $50. People like these, even though they're totally passive and the battery is just for the lights. With that money you can buy a $15 AB box used, like an old DOD or something, a $15 switch, and an extra jack. You'll make money andn have a less valuable piece of gear to "destroy".

Good luck.

great question...
good answer.
I'm presently trying to figure out something very similar for my rig...
thnx for the basis for thought guys.
