At first I tried using the POD without the software. That was painful. I couldn’t believe that it was harder to program than the GT-5 because that was renowned for being difficult, and here was this modern bit of kit that was worse.
All power supply leads are kak these days. It doesn’t matter how well built the unit is, it’s let down by a puny plug and string cable. The Beat Buddy has exactly the same problem, as did the Hughes & Kettner Tube Factor.
I wouldn’t try to fiddle with the POD at a gig. Sometimes I might get the EQ a bit wrong when I customise the tone to a new guitar. At home at low volume it sounds fine, but at performing volume its always different. It’s usually got too much top. I allow for that and can usually get it pretty close, but sometimes have to tweak it once I’m home again.
