I upgraded my Carvin CT6M with some Fishman Fluence modern humbucker blacks. The original pickups where the Kiesel/Carvin Allan Holdsworth HH2 model. The new Fluences are the modern ceramic for the bridge and alnico for the neck. The bridge sound like a typical modern high-output humbucker. The alnico one sounds really interesting and very vocal. I enabled the second voicing using the push-pull tone knob. The volume push-pull controlls the coil-spit which enables the out-side cores on each pickup as single-coils. With the coil-tap, the neck sounds like a Strat with a bunch of vocal honk sound. Very bluesy.
