Client wants me to transfer an Anthem system I fitted (some time ago) to a Sigma 000 to a new guitar I'm building for him, but I'm having difficulty getting info on the size of the slot for the soundhole brace it fits over, and it's spacing from the soundhole edge.
I had to fit a spacer each side of the soundhole brace on the sigma, but neglected to note the info I need.
Can anyone help out? Maybe photocopy one if you have it to hand and tell me the depth/width of the slot?

Also, separate question - I have 1mm thick Self Adhesive Sticky 3M EVA PADS, will these be suitable for re-attaching the pre-amp and the microphone pick-up?

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Oh! A couple days too late. I moved one from a J45 to a HD28 on Friday for a fellow and could have taken measurements for you. But pickup, guitars and owner are now all on a plane headed somewhere.

I have used 3m foam mounting tape where factory pads were unavailable and seen no failures so far. Have heard about failures using off-brand tape.
