Hi Pat,

I've posted about the using a JamMan a couple of times. In the past I've used players CD/MP3, but for the last three+ years I've been using my JamMan solo XT with an added SD card and FS3X foot switch. I have plenty of space and use WAV files. Plus the added advantage for me of the JamMan is that as a foot pedal, it is hands free. I can stop and start and scroll through songs using the FS3X. I just assign each song a loop number that's written on my set list. As a guitar player this works well for me, plus I think it's a better look to the audience...not a lot of button pushing between songs. The song quality is great through my Bose L1 Compact.
