regret: mint jupiter 6. i often miss my soundcraft 6000 too... yeah it was grainy with a midrange smear, but i really miss having a full console with knobs for everything. plug-ins slow me down so much.
Ouch Meriphew! A Jupiter 8. My biggest regret is selling my Roland Juno 60. At the time, I needed to sell it to buy an Ensoniq ESQ-1, which was the greatest thing in 1985. I'll probably pick up another Juno 60 someday for old times sake.
Regrets: Early 70's Marshall Plexi 100 watter, 1974 Ampeg V2 head w/vox 2/10 cab. Gibson Les Paul Custom late 70's, 1980 Dean Elite, (Almost sold my Meek SC2 recently, glad I didn't! It's a secret weapon!)
