Hi Gordon,

I am certainly not knowledgeable about what is most prevalent in guitar amps being used worldwide. I guess that it depends on the artist's preferences. Not so long ago, Nick Jonas guitar tech called me to make an emergency repair on a custom tube amp.

The amp was hand-wired point-to-point with no schematic. I had to call the builder to be sure I did not screw something up. He was happy to help me on the phone, and we solved the issue. Perhaps this is an isolated case of one artist who uses a tube amp.

Most local guitar players I know are using tube guitar amps. As I said, I don't know what is most prevalent nowadays.

I will comment a bit later on the PA issue. My wife is calling...lol
