I installed the set of GFS Surf 90 pups in my Eastwood Coronado yesterday morning ( strung with 11's if that makes any difference to anyone ). Very easy to install, well built and pretty cool looking. The Coronado is a chambered mahogany guitar that came stock with a pair of uber - hot alnico humbuckers. I felt the tone was a bit muddy for my tastes, so I pulled the trigger on a set Surf 90's. I ran the guitar thru multiple head and amp combos ( PRRI combo, Vox AC4 / 12" cab, Epi Valve Jr with Bitmo mods / 12" cab, Bronco combo and old Newcomb converted head / 12" cab ) and came away with the following conclusions. 1) Very twangy, but with more low end than a typical Tele bridge. 2) Tone control makes a huge difference on the bridge pup. You can really dial back the twang. I used it dialed back to about 60% - 70% most of the time. 3) Nice match with a chambered body. 4) Neck pickup has a very nice rhythm tone, but a bit on the nasal side with some amps ( Vox especially ). 5) Great pups for playing surf and 60's instrumentals. It kills on " Walk Don't Run ", " Pipeline " etc. type songs. I used the onboard reverb on the PRRI and my Boss FRV-1 set at pretty low reverb for the other amps. 6) Pairs very well with the Danecho pedal for a delay / echo sound. 7) You can play some OD rock with these pups. I played a host of AC/DC with these pups yesterday and they sounded very good. In fact, much better than I had anticipated. In closing, if you are looking for a nice middle ground between the Tele twang and the humbucker growl, this is a good pickup. Definately brighter than the GFS Dream 90 ( I had those a while back in a solid body mahogany Tele ). If you want that surf tone, these will deliver. Sorry guys, but I do not have any recording equipment to post audio clips. Perhaps one of our other members can do this.
