Somewhat out of the ordinary, yes.

The internal tone control was generally

considered a sales gimmick. They were

seldom effective and would often rattle

or buzz.

Most players ultimately removed them.

( Much like the "ashtray" bridge cover

on a Tele or Strat )

My '64 Hollywood Ace doesn't have one

and it is by no means a "Monday drum".

Likely a custom order which was easy to do

back in the day.

To find a proper specimen will be costly, unneccesary

and as an after factory add-on detrimental to the

value to collectors.

This gang is pretty hardcore about that...

Love to see some pics!
