Well thanks for the input. I am happy to report there was no "fill and drill" needed. Next I am working on the electronics. Taking them back to the way they were with no toggle switch. The pots should be: 1. Vol. 2. Bass 3. Treble. The toggle switch is connected to the EMG Phase Shifter circuit board. Totally useless in my world.
And below is the story of this bass.
I got this recently from my drummer who back in the day bought it from Tim "Stungun" Stunson, the former bassist with Blackfoot. It's a Robin Freedom bass with some mods, some be me and some before I got it.
I called Tim and asked him some questions about it and he told me that when he was in a band here in my area called Intimate Action back in the late 80's his guitarist caught the attention of the Robin people out of Houston. As a band they went there and got a tour. They then were taken to an area with the custom guitars and basses and were offered to pick out one they liked and were sold to the band at a large discount.
This bass has seen action all of the US and maybe outside as well. He couldn't exactly remember but he did tell me he wishes he had it back. Sorry Tim, it's mine now. Lot's of people here have Fenders, Musicman (I have one), etc. But not a Robin and not one with this kind of history.
Here are the mods before I got it.
*--Original Rio Grande pickups replaced with active EMG's
*--Original round string retainer replaced with a bar type and and additional smaller bar added for the E and A strings.
*--Toggle switch where one of the original knobs was. It is wired in and I asked Tim what it does and he didn't recall.
My mods just completed.
*--Original bridge (unbranded) replaced with a Babicz
*--Original tuners (unbranded) replaced with Grover Wavy Titan in a 2+2 config. I had to reverse two of them and they were a "just right" fit as you see
*--Original strap buttons replaced with Dunlop Straplocks
