Wrap Around Bridge Help.

[Lamf77]

So I am debating taking on another project (to add to the already uncompleted list). I have a Epiphone SG, as well as some John Birch pickups. Tony Iommi removed the tailpiece and tuneomatic bridge, and put a wrap around bridge in the regular tuneomatic spot. Simple enough? Does anyone know what the black circle shims/washers are underneath? I assume they to raise the bridge a few mm. Possibly underneath the studs which go into the guitar? Any ideas or suggestions are welcome...thanks!

Ya got to do what ya got to do to get the string height where it needs to be.

True ....but what are the black washers exactly? Need to know what to order?
After reevaluating. HOles for bridge are wider. So most likely drilled new holes and used plastic to cover?

So I am guessing that you have Tony's guitar pictured?

I am going to guess those black washers are for cosmetics (sitting around the stud and under the wrap bridge) and are covering the woodwork which was necessary to install this. The original 1965 SG Specials had a wrap-bar which looked like this:

Since they were roughly intonated for 11's with a wound 'G', the owner wanted an adjustable intonation bridge. I'll go out on a limb that (like many here experienced) the stud spacing or stud size was not the same, so the installer glued a wood plug into the original holes. He then drilled the new holes and did not want to refinish the guitar, so just covered them up.

I've seen a few guitars with strange cover-ups and I don't believe the black washers are mechanically functional.

Thanks Rob for what may be the definitive answer. Initially I did not anticipate permanent changes to the guitar such as new drill holes. I may just install the John Birch pickups, buy a monkey sticker and call it a day! Thanks!

Did you ever finish the Ace Les Paul?

I am not a big fan of wrap around bridges because of the intonation problems you can encounter. I have a PRS SE Zach Myers that has the factory wrap around bridge, and IMO they are a fantastic bridge, but they have adjustable saddles. I really like that PRS Wrap Around I think every guitar should have adjustable saddles.

THIS IS THE PRS WRAP-AROUND

Unfortunately, no. It's near the top of my list though...just need to keep the wife and kids off my back...lol.
