Hi JW!
Thanks for the nice comment about my tone. I used a Peavey Nashville 400 and a Goodrich volume pedal to cut the C6 Non Pedal Course.It was custom made for me by Goodrich. The Rickenbacker Frypan I used has an unusual large horseshoe pickup. Much fatter and wider than all the other Ricks I've seen. All I did was plug into the amp and pick. I do use a Boss DD3 Digital Delay on live performances but I don't think I used it on the course. I set the delay where it makes my amp sound like you are playing in a large hall - such as a church... Of course, like all the other players, I have my own touch and tone when I play. I can usually find my tone on any amp that I use. My string gauges are:

1 - E 015
2 - C 018
3 - A 022
4 - G N24
5 - E N30
6 - C N36 (also for when I raise the 6th string from C to C#)
N = Nickel Semi Flat

The Rickenbacker is the long scale or 24 1/4".

As I don't have the Nashville 400 amp anymore I do not remember how I set the controls. I do know that I put the bass knob on 10 and the treble knob at about 3 o'clock. If you have a Nashville 400 amp you can set the other control knobs at 12 o'clock and back them off one way or the other to suit your ear.
