FREEDOM CUSTOM GUITAR RESEARCH Tone Shift

This is a set of three items: FREEDOM CUSTOM GUITAR RESEARCH's Tone Shift Plate SP-JP-01 and Tone Shift Plate SP-JP-03, and a genuine Fender neck joint plate.
The Fender plate is 2mm thick.
The Tone Shift Plates are said to extend sustain and lower the tonal center, making a noticeable difference. Please try comparing all three.

I prefer a vintage-like sound, so I attached these for about two months before removing them.

Shipping will be via Nekoposu (Japanese postal service for small packages).

Thank you for looking.
