Re: Trey Anastasio's Pickups?
Duncan 59s are used now and have been for a while. Not sure if they were are early as '91. Ive heard he used schaller golden 50s at one point early in his career. But you could dial in the early tones with the 59s for sure. I know Paul modifies them slightly to make them hum cancelling when tapped/dropped and i think he also rewinds the bridge a little hotter for what he decided was a better balance.
The schallers are pretty hard to find but i think you can order them from germany. A very close copy are the stew mac golden 50s but honestly i think the duncans are better than both. Unless im wrong, he switched from a mesa to a heavily modded deluxe reverb around 96/97 along with the new koa languedoc which had the 59s. My bet is you wouldnt hear too much difference between the schallers and the 59s through either rig but you would hear a lot of differences between the mesa and the DR using the schallers or the 59s.
