Hey Harley, well that makes much more sense of it. What happened here in Oz, I saw an advert for a programmable preamp, not the MP-1 and at the time I was using my 73 Marshall through a power soak (so you could be in the same room as it

) but I had no lead boost

. Nunzio Gambale (Franks Brother) who owned Pro Audio asked us what we wanted him to look out for at the NAMM show he was going to, so we (I) told him I wanted a programmable tube preamp that sounded as good as my Marshall but let me have a lead boost. He came back with the MP-1 and I was in heaven. Later on he made the split stacks/cabs etc here under licence. So we got MP-1, MB-1 (he's a bass player), B200s, B500b and G500s and later MP-2, no effects.
Interesting with MP-2, I get why some find it confusing, for me it was like, yeah hupp, bring it on but then I'm also a sound engineer and was running my rig like a PA and suddenly I had a bunch of other options. Of those though, I didn't need the parallel loop as I used a mixer for that (though using it now for the first time in my cut back 4RU rig), but the cab sim outs were perfect, and the gate very much needed for the crazy amount of gain the MP-2 has. I like the wah but I use it on auto triggered and not that much, good for hendrixy stuff. Of the RTM, I've only ended up using the stereo master vol control for (up until later) the only expression pedal I had, which I find very useful with the way I play these days, basically turn up the vol on the same patch for lead. As I'm sure you know, you can run the MP-2 quite simply and not bother with the bells and whistles, I've rarely futzed with the graphic eq.
I get what you mean about the macros, however I've never tried them out and the RTM combinations in them I'm sure are worth trying, or the ADA dudes wouldn't have included them. That's one thing I've always loved about ADA gear, it's well researched and thought out as in, this is what live guitar players (and bass players) want.
The A/B A+B pedal I have is one I built modifying a Peavey (ch/rev) amp switch pedal. So it selects 1 or other or both output jacks for the input to go to, real simple, just 2 switches and 3 jacks wired up. I made it to select between Marshall 50 input or Rockman X100 input (or both

). The X100 head phone out into 2 x 1/4" jack leads with voltage divider resistors (to drop the HP signal to guitar level), 1 to Marshall 50 (2nd input) the other to Marshall 100 Artist head. That was my lead boost prior to MP-1, when I first got the MP-1 I also fed it a signal and brought back the A/B outs into the X100 stereo input (TRS input for stereo in to the X100 to play along to..), until I got the B200s and Quadverb and mixer, sold the Marshall Artist to pay for it all.
