Fender American 2-point tremolo w/ pop in arm
When it comes to electronics since this Strat has two single and one double pickup, the single pups both have a 50k pot(one per pup). The ShawBucker has a double 250k or 500k Pot. I highly recommend that one listen to the amazing Shawbucker sound.
Tap image and listen to Tim talk about his design
Pickup Guru Tim Shaw designed the double coil in this guitar. Shawbucker!!!! I personally have been a fan of Shaw pups since the early to mid 80's Gibson era. If you were lucky enough to have a Gibson with Shaw designed pups then you know what I am talking about. Tim was dedicated to replicating the true essence and sound of the 59 Reissue or The Holy Grail...
