Does anyone have the bridge routing dimensions, length x width x depth + mute channel width x depth for a '77 4001. I'm trying to restore the factory bridge where somebody filled it in. Any help would be appreciated

Okay, Wes. Straight from my 1979 4080 which will be leaving me very soon: the main bridge route is a trapezoid with rounded corners. It is 1 3/4" wide and 1/4" deep except where it accommodates the mute: 1/2" deep. The "shorter" side is roughly 3", and the "longer" side is roughly 3 1/4". Bear in mind that both sides would be slightly longer if the trapezoid had sharp corners. As for the mute channel, it is 3 3/4" long and 3/4" wide, with rounded ends. I hope this helps.

Will that 4001 ever return to its former glory?

Wints, what were they thinking?! What bridge was that routed for?

Looks more like it was routed for an ashtray.
No, a real ashtray...

John,
It's original one!
That's the 70's version of how to lower the action!
1. Rout body an 1/8th" give or take a fraction.
2. Cut holes in your pick up surround to let in the new low action!
Oh, for a truss rod tool and this forum 30 years ago!

Thanks Sergio. You know you could have just sent me the 4080 for a while and saved the hassle of measuring! (insert one of those happy faces here)
