I still have/use an original Pod Pro. For live, I run it directly into a Crown D150, then into an old 2x12 cabinet. Never had a complaint about the sounds, and it covers any sound that I'll ever need. Two points. You really need the footswitch board for live apps. Also, the internal reverb is kinda suckie, but a good reverb could easily be inserted after the Pod.
The other night we were tracking a Motown type tune, and the bass just didn't sound right. For kicks we inserted the Pod to the recorded track.. using EQ, compression and a little overdrive. Mission accomplished! Surprised the hell out of all of us. Good investment if you can catch a deal.
Best, Paul
