I have a JamMan Stereo. I like it a lot, but for my purposes it has a few flaws. The JamMan Solo XT seems to address some of these: The JamMan Solo XT allows you to set the tempo of a loop via buttons on the pedal itself, with a BPM display. The Stereo requires you to use tap tempo (very imprecise, in my experience) or connect the pedal to a computer and use DigiTech's JamManager software, which is a fiddly and somewhat time-consuming process. The Solo XT is "modular," meaning that you can bring just the relatively compact pedal itself for simpler looping tasks, or add the accessory pedal for scrolling through loops with your foot, stopping a loop with a single click, etc. With the Stereo, you're stuck schlepping around a large, fairly heavy device, regardless of the requirements of a particular gig. The Solo XT runs on a battery or a standard 9V power supply. [EDIT: My mistake; it does not run on a battery.] The Stereo requires a proprietary power supply and does not have a battery option. If I'm not mistaken, the accessory footswitch unit has "soft" switches. The switches on the Stereo are loud, plus they have long travel before engaging, making timing tricky at times. The Solo XT allows you to synch multiple units, whereas the Stereo does not. This feature is not of interest to me now, but might be in the future; who knows?... On paper at least, the Solo XT plus footswitch combination seems to offer everything that the Stereo does and more, at a lower price. What I want to know is: Am I missing anything? I'm interested in selling my JamMan Stereo and buying a Solo XT, but I'm wondering if anyone who has had experience with both devices knows of anything I'd be sacrificing by doing so. Thanks in advance!
