Callaham Trem Arm, Virtual Pop-In (LH)

These arms are left handed.

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 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 designed for use only with Callaham blocks, they are not appropriate for use with Fender blocks. Use Callaham's fully-threaded arms for Fender blocks.

Callaham's pop-in arm has a shortened thread length compared to traditional arms (see photos). It is therefore unthreaded where it bears against the Delrin bushing in a Callaham block, and this allows you to push it in, then spin it once or twice to engage a thread or two. The threads are there simply to keep the user from inadvertently pulling the arm out during use. So the arm is virtually a pop-in design (though engaging a couple of threads is suggested), 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.
