I'm a little late to the party, but from an interiew in Vintage Guitar Pete said, “Only one guy modified that amp, and his name is Jim Williams. He told me that Deluxes had a middle control, but it was a value that Fender shorted-out on the chasis where they didn’t use a knob. It’s like a preset middle control that helps shape the amp. He said, ‘What I do is take this middle control value and put it on 10, because it’s on 3 or 4.’ I asked him to do that, because I think the guitars live in midrange. Once Jim gave me this middle control, I put the treble on 5, the bass on 21/2 or 3, reverb on 21/2, and the volume somewhere between 31/2 and 51/2. After 5 or 6, the Deluxe just flattens out and keeps compressing. That was the sweet spot on the amp."
The whole interview is pretty good and worth a read http://www.vintageguitar.com/2995/pete-anderson/.
Has anyone made a video or recording with a 1 to 1 comparision of the Deluxe and the Pete Anderson Custom model? I'm using the Deluxe Vib as my go to amp and I'm interested in the PAC. The other amps in the vintage model pack don't really interest me so I can't really justify spending $50 on trying an amp to see if it is way better than what I am using at the moment.
