Callaham Enhanced Tremolo Block, American Standard

Country of Manufacture: USA String Spacing: 2-1/16" (2.062" / 52.4mm) Enhanced Vintage, w/ 10-32 Thread Fits Fender American Standard; Strat Plus Deluxe This block fits most American Series bridges, but it does not fit the American Deluxe or Strat Ultra. You can use your standard tremolo arm with this block, though a Callaham virtual pop-in arm is strongly recommended for best results. All Callaham blocks are made of 1018 cold-rolled steel like the vintage originals, which contributes to the sustain and harmonic content that has made these guitars legendary. Replacing a block made of inferior materials (zinc, leaded steel, sintered steel) with one of Callaham's blocks will get you one step closer to those $50,000 originals. All have a precision-machined top surface that is free of paint to ensure solid metal-to-metal contact with the top plate, for optimal tone. And all Callaham blocks come with a precision-reamed Delrin insert in the arm hole, allowing the tremolo arm to fit snugly
