Howdy Rick & Loopers all -
My fave rave mixer is the Soundcraft EPM series. I use the EPM6 for my looping gigs, and a Soundcraft Gigrac 1000 for band gigs. Very transparent, rugged construction, versatile, and a great feel to the controls - you roll something back to 10:00, you HEAR it, and you can keep rolling back and HEARING the change.
"Without music to decorate it, time is just a bunch of boring production deadlines or dates by which bills must be paid.
