Can you elaborate on the intonation problems you had with the amp?
I may have to rethink my decision to try out stand up comedy.
No amp problems. In fact, this is my favorite amp I've ever owned, although a Fender PA135 I picked up on a whim is growing on me, as long as I don't have to carry it anywhere.
Intonation problems come from the player (i.e., me) and/or the instrument. It was a line from a Frank Zappa song "Joe's Garage", from an album of the same name, an all-time classic IMO. However, if you choose to google it, many of the other songs on the album are not suitable for work or recommended for listening in the company of your mother or spiritual adviser.
