I have a PTP SD-30, so no modern mids. I'm currently at the following,
Master to taste
mid - noon
treble - noon
gain - about 3 o'clock
clean volume about 10 o'clock, bright switch is pulled depending on the guitar.
I have the channel volume mod, with a pot on the back and it's up about 80%, I do wish I had more range so I could have a little more range on the clean channel.
