No MJMP, you can't have to many
And anyone who says you can't play them all at once is wrong (but you'd need a decent input splitter and a 24 ch desk LoL) Wow wall of (7) MP1s'
And that's doing it simply, you could get even more creative and use MP1s in other MP1 loops (and then there's all the great ADA FXs you have
).
I bought my first MP1 in maybe 87 or 88 ? it was one of the first batch to come to Australia. I sold it to MikeB in ~95
so I could buy the new MP2. My first MP2 died at a gig not long after I bought it
(only catastrophic failure I've ever had with ADA preamps BTW). Fortuitously, Mike was at the gig and lived down the street, so he wizzed home a lent me my former MP1 for the night (go Mike, still very appreciated my friend
). So I swapped that unit for a new one which is still in my live rack today, only change is new tubes. I have 3 other MP2s (I started buying them as there still isn't a replacement I like and they are getting on..). I have one in my studio rack and the other 2 gather dust (which I'm not thrilled about..). I also have 2 MB1s' they came from the US and have both been to MJMP for a refresh and MDRT transformers. One in my live rack and one in the studio rack, they both get used regularly..
I recently bought 2 MP1s, 1 240v AU model (has issues which eventually I'll solve) and 1 US model (seems to be a decent solid unit), I know little about either of them except I bought them from a guy in my home town Newcastle, one has battery mod (IIRC the 240v one). When I get some head space I'll get them both optimal and add one to the live rack and one to the studio rack.
I still need a 240v MP1 Classic, they didn't make it to Australia (as far as I know).
