I know there are lots of threads out there on the Bass Pod and altenatives, but none that seemed to address this issue specifically, so here goes... I'm travelling a lot for my job these days (non-music related job), spending countless hours in hotel rooms. I figured it might be cool to travel with a bass and a headphone amp, since I don't have the opportunity to play much anymore... So, in considering alternatives, two jumped out at me: Bass Pod XT (for specific use as a headphone amp) and the Cafe Walter. Each seems to have its pros and cons from what I can tell. What intrigues me about the Pod is the diversity of tones, a big selling point to me now. But the pain in that decision comes from the fact I can't seem to find any information about plugging in an mp3 player to play along with. That's where the Cafe Walter comes in...this unit has the ability to plug in an mp3 player, but lacks the tonal diversity of the Bass Pod XT. What I'm asking is for people to either dispell either of my two concerns or to offer good sounding alternatives (and please don't recommend either the EBS Microbass - which costs too much for my needs or the Pocket Rockit - which didn't sound good to me). Thanks for your help!
