I have the same sorts of issues from time to time with my podHD500 and DT25. It's one of the reasons I'm selling the DT25 (keeping the podHD for practice).
The Line 6 fanboys on this site will tell you DT amps are somehow the best amps in the hisoty of guitar music but its just ridiculous and not the case. I know from personal experience and direct comparison that they dont play (or feel) as good as other amps, even in the same price bracket. Line 6 make classic modelling units, no doubt, they are not a manufacturer of classic amps.
Not so sure I agree with you. Yes there are a lot of folks on this forum who swear by their amps. Thats because they are having a good experience with the amp. I don't think that people are over selling the DT's as the best on the planet. But if you are a "fanboy" and really enjoy you gear, you are going to share your experience with people. I don't believe that too many people are delusional in their zeal for their DT's. Some maybe, but not all.
Set aside some of the tweaky problems that rear their ugly head from time to time, I think the amp sounds purty damn good. and the Dream Rigsounds fantastic! And I am comparing it to amps that cost thousands of dollars! Now if you really want to meet annoying "fanboys", talk to someone who just spent $6k for a 35 watt combo!
Bring a lunch cause you're gonna be there for a while!
