Callaham's Virtual Pop-In arms are designed for use only with Callaham's Enhanced Vintage blocks. These blocks are used in all of the Callaham trem products we sell, including complete tremolos, and upgrade kits. Enhanced Vintage refers to the fact that Callaham inserts a Delrin sleeve into the block's arm hole, which mitigates any play in the threads, resulting in a better trem feel.
Note: These pop-in arms are not appropriate for use with Fender blocks. Use Callaham's fully-threaded arms for Fender blocks.
Callaham's pop-in arm has a shorter threaded area than traditional arms (see photos). It is therefore unthreaded where it bears against the Delrin sleeve inside the block so that you have full contact between the sleeve and the arm, eliminating play in the arm. This allows you to push it in and use it, often with no need to screw it into the block. If more aggressive users find they inadvertently pull the arm out of the block occasionally, they can spin the arm a couple of times to engage a couple of threads, which will prevent this. So the arm is virtually a pop-in design - hence the name.
Specs
Callaham's arms are made of stainless steel, so there's no plating to worry about, and the arm will never corrode. Also, if you bend the arm to suit your playing style, you don't have to worry about plating flaking off like you do with a plated arm.
- Made in USA
- Thread: 10-32 UNF
- Compatible with Callaham's Enhanced Vintage Blocks
- Tip color: parchment (we stock Fender tips in other colors at extra cost)
Note: Callaham's pop-in arms are suitable for use only with Callaham Enhanced Vintage blocks (all Callaham blocks are Enhanced Vintage unless special-ordered without this feature). If you have a traditional threaded block, then Callaham's fully-threaded arms are what you'll want.
Lengths
Callaham makes arms in three lengths, please see images for comparison.
4-1/8" | 105mm (DG) - Based on the stubby arm on David Gilmour's famous black Strat
5-1/4" | 133mm (64) - based on an original arm from a 1964 Strat
6" | 152mm (FE) - based on Fender's current production
Works perfectly with the Callaham bridge
Solved my issues with high E sliding off the fretboard. Made with quality material. Couldn't be happier.
Arm is almost identical length and size to a genuine 1963 (body and neck are stamped '63; pickups are stamped '64 - meaning this Strat was assembled over the new year's break between 63 and 64). See photo for comparison. Original arm had snapped off in tremolo block and the shortened stump was rethreaded. Sadly, it wobbled far too much for my liking. Matched with a Callaham Vintage block, the Callaham arm is superb quality, and no regrets with purchase.
Just Perfect.
Perfect match for the Callahan Narrow Vintage Strat Bridge installed on an upgraded Eric Clapton Strat I purchased from another guitarist. They had the bridge locked down and included a Fender arm. When I set the guitar up to float the bridge I found the Fender arm was of poor performance and quality. Bought the 64 with the shorter length to try something different than current specs and I am glad I did. Absolutely love it and ToneShapers customer service was excellent.
