Thanks for the positive feedback, all!!
MikeB - when playing gigs and/or in the studio, I like to keep things very simple. I only use one preamp/poweramp at a time. One ADA MP-1 preamp and a poweramp though a 2x12 or 4x12. In addition, I run only ONE of my rack multi-effects units at a time in series with the MP-1 for some very light reverb/delay - Intellifex, Intelliverb, etc. I am always experimenting with different sounds/tones so I like to "mix" things up a bit and try adding different pedals once in a while for added color, etc.
mqqse - yes only one JMP-1. I picked it up a few years back used at a decent price and just couldn't resist. Always wanted one. It works/sounds great!
Kim - all 4 of my MP-1's are completely stock and work/sound great! 3 of them are version 2.01 and 1 of them is version 1.38. The only work I've ever had done was I replaced the battery on one MP-1, and changed the filter caps on the tube board on another one as it was humming a bit. But all are stock - no mods - nothing. I picked up that Line 6 unit a few years back used (pretty cheap) just for fun. It is a well made unit and it sounds OK - clearly the drive is NOT on the same level as an MP-1 or JMP-1. My favorite head ever made is the original Peavey 5150 head as you can see from the photo. It has it's own unique sound which I've always respected. I have a bunch of stompboxes - BOSS, TC, etc. and like experimenting with different sounds/tones, but in all honesty, at the end of the day, nothing, nothing at all, sounds as musical and as transparent as my ADA MP-1 preamps. They are just in a class of their own - so very special.
Dante - good catch, my friend! Yes, that is one of my beloved 1976 Ibanez Concord acoustic guitars. I am a HUGE fan of the older Ibanez stuff. Specifically, the early 80's Roadstar II models. I can talk mid 70's early 80's Ibanez all day long! The craftsmanship is just truly amazing.
rnolan - thank you!!
