Selmer Radio Improved Alto
July 14, 2021
This alto saxophone belongs to Benn Clatworthy and is in for an overhaul and polish. Note: I never use buffing wheels on saxophones so as to preserved the integrity of the tone holes and engraving.
Here are some photos after disassembly. Note the half-round cork in his D tone hole.
The purpose of the half-round cork as seen above is to tune the middle E.
Putting cork across the top of the tone hole produces a different effect than altering the size of the tone hole. The cork causes the middle E to be lowered approximately 20 cents before the low E is affected by the change in venting. This helps keep the middle register of this horn in tune, as a sharp middle E is a problem that plagues many older model saxophones.
