Callaham Enhanced Tremolo Block, Mexican Standard

• Country of Manufacture: USA
• String Spacing: 2-1/16" (2.062" / 52.4mm)
• Enhanced Vintage, w/ 10-32 Thread
• Fits Fender Standard Stratocaster (arm required); Classic Player Strat (arm required); Highway 1 (2006 and later)

You cannot use a Standard or Classic Player tremolo arm with this block, you'll need to select a Callaham Virtual Pop-In Arm. You can use the stock arm for a 2006-and-later Highway 1 Strat, 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 $30,000 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 and be free of play, without requiring a spring in the hole, as Fender's threaded blocks do. This gives you the best tremolo feel available, and no worries about losing springs (in case you're unaware of it, new Stratocasters ship with a round label over the arm hole in the tremolo - the label's purpose is to prevent the tiny spring from falling out and being lost). With Callaham's blocks, the need for a spring is eliminated.
