Finally played a few gigs on my new TH 500 and its a cool little amp. Sounds good, has a nice midrange with my DB 112. I still like my AG500 better it just has the sound i love but the Th 500 is really cool. The drive feature is very nice and the size of this amp makes me feel guilty on load ins. It is so light and small that i started helping the keyboard player with one of his keyboards just so the band doesn't get too jealous. Even tho the sound isnt as big as my AG500 i still have no problem using this amp on most gigs from now on and the sound guys really like the head. People say this amp sounds a lot like the DB751 but ive never played a DB751 so i wouldn't know, but would love to do a sound comparison one day.
