I have them in the Koa Sister, solid slab Koa body with Braz RW neck. Wonderful with that, a Custom 22 so thinner body (Koa in a SC body would weigh a ton!)
Warm, woody tone and a touch on the bright side.
I also had them in my now departed Bahamma Mama MkII SCT. Obeche body (very light weight), maple neck with cocobolo board. Fabulous in that - incredibly stupid of me to trade it in on a SC594 SH which I never bonded with.
Always wanted to try 53/10s in a HB, just like Herr Squid for those classic Rush tones!
