Anyone know how to integrate an FX pedal circuit onboard an amp?

HaHa, that's cool. I knew what you meant though.

Hi soulscry.
OK, then the basic idea is this:
1) do not touch or modify your amp, at least for this reason.
2) build a "box" , mounted on your pedalboad that sits on top or besides your head; it contains a pedal power supply , and a switcher relay, powered by that same power supply, to keep things simple.
On that pedalboard you have your sonic maximizer always connected, and one or more pedals (your choice) which are remotely switched by a new circuit.
3) You will have your original FX Loop switcher always on, to enable the pedalboard.
4) You'll have to run an extra cable and mount a footswitch somewhere close to your Peavey switcher.
I'd suggest mount both side by side into a piece of plywood, and join both cables with heatshrink every, say, 8 or 10 inches, which essentially turns this mess into a single (larger) pedal and a single (thicker) cable for all practical means.
On the amp side, you will plug the original Peavey multipin plug where it belongs, and the new plug into the box.
Since you can use a 3 conductor wire (or microphone cable) and a stereo plug, now you can switch *two*effects chains if you wish
5) You will not use the original Fx loop footswitch (you leave it always on), unless for any particular reason you want to remove everything from the original loop.
6) Build that supply yourself, so you have 12 to 16V "raw" (filtered but not regulated) that you can use to power 12V relays and associated Leds if you wish, and power your pedals thanks to a 7809 regulator.
I think that with this you can design it yourself, but if you have any doubt, you are welcome.

I guess it comes down to not modding the amp and making a complicated external switcher or just modding the amp for a main in jack.

Yeah, the idea of the external switching design is not a bad idea at all. And I will definitely keep it in mind if I can't seem to work out a simpler way. Simpler may not be the term for means to get there, but by the end result and amount of pedals and connections I have in the end to deal with. I'm trying to figure out how to do as much as I can within the amp from what's already there and get the most out of it's components I can while adding as little as needed to get the desired result. Again, all for simplicity's sake. Adding a "main" or "power amp in" jack seems to be probably the simplest of all. Also with the added benefit of being able to run the Sonic Stomp at all times in conjunction with my ISP Decimator G-String using it's secondary ins and outs. The Decimator in the Loop kills all the hiss. But there again, I wanted the FX Loop for just delay. So a "main/poweramp in" jack would allow me to have the Sonic Stomp and Decimator constantly in the loop independent of the footswitch. I just need a little more guidance as to any specifics on installing such a jack. Or is it as simple as running a kind of send and return wire intercepting the signal before the master volume and taking that to a jack? Thanks alot guys, you've been such great help
