I've gotten a lot of use out of my RC-3 but it's time to upgrade. I want to be use this for live solo gigs and trigger pre-recorded bass and drum tracks that run on one channel and send out to the PA and then make guitar loops with the second channel and send that out to a guitar amp. Also do more "traditional" looping, i.e. making it all up on the spot. Presets are a must, 40-60, enough for a whole show. I also want something quieter than the RC-3. I'm hoping someone here has some insight into some of these loopers. It can be difficult trying to figure out just what each can and can't do. My list so far: Top 2- EHX 22500 - seems to have what I need. Used price around $220. Pigtronix Infinity - also seems to have what I need but somewhat limited with 50 presets. But gets lots of rave reviews as the best sounding looper on the market. Used price $300. Also considering: Boss RC-300 - 3 loop tracks. 2 things I don't like: a) subsequent loops are limited to the length of the first loop. b) expensive used price around $400. EHX 45000 - 4 loop tracks. Looks nice but a little pricey at around $400 used. Boomerang III - this seems to be the Cadillac of loopers but a) expensive used $500+ b) hard to find. Looked at but rejected: Digitech Jamman Stereo and Soloist XT Ditto x2 & x4 Boss RC-30 Thanks for any suggestions/ideas/comments.
