Callaham Enhanced Tremolo Block, American Deluxe, With Arm

• Country of Manufacture: USA
• "Pop-in" Arm Included - Choose Length
• String Spacing: 2-1/16" (2.062" / 52.4mm)
• Enhanced Vintage, w/ 10-32 Thread
• Fits Fender American Deluxe; Strat Ultra

This block fits American Deluxe bridges, but it does not work with the Fender push-in arm. For this reason we include a Callaham arm in the length of your choice:

64 (5-1/4" length - based on '64 Strat)
DG (4-1/8" length - based on David Gilmour's black Strat)
FE (6" - based on current Fender production)

Please see the image of the three arms to help you choose which one you want. We stock Callaham's arms with parchment tips only -- because we stock the full spectrum of plastic parts from Fender, we do not stock other colors from Callaham.

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 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.

The Delrin bushing is the feature that defines the Enhanced Vintage design. Since Fender's threaded arms (or any arm with a 10-32 thread, for that matter) can be used with Callaham's blocks, you are not forced to buy a Callaham arm for use with your Callaham block, but it is highly recommended. However, because Fender's American Deluxe guitars come with a snap-in arm, the Fender arm is incompatible with Callaham's Deluxe block. For this reason, when you purchase a Deluxe block, a Callaham arm is included.
