There's a bunch of ways you can patch it all. The main consideration is to ensure you keep your gain structure as best it can be. Like Chamai, I've always used a mixer and run the rig a bit like a PA set up. I use an old Yamaha AM802, 8 ch with 3 FX sends, I have it velcroed to the bottom of my rack. Running in stereo makes a BIG difference so as Chamai said it's the best way to go. Start simple and bring in things as you experiment.Some things to keep in mind:The MP1 loop uses a dual ganged opposing pot, so as you increase the send it decreases the return and vis versa. Don't mix line level and inst level devices in the loop. Best just use one device say the eq, that's probably a good spot for it or maybe the DOD FX96?.You need a stereo power amp, the Microtube (which is a hybrid amp, tube input SS output) would work well, is 1RU, not too heavy and not too loud.Either get another cab or re-wire you 4x12 so it can be stereo. Thus it will handle 60w per side which will match well with the Microtube (or a 50w per ch amp e.g. a Carvin TS100).Delay and Rev are best after the MP1, you can chain through it in stereo (some call it the 4 cable method) and mix your wet/dry balance in the FX (Intelliflex is good, or Quadverb etc). OR if you use a mixer, use one FX send L and one R and return into 2 channels pan L & R.
Wah is best up front as would be the MXR boost.Let us know how you go and what works for you... Also there's lots of posts here about what others have found good for them.
