Hi Ike,
I'm looking forward to seeing the replies to you question!
My story is that I acquired a four-year-old Englehardt bass last year that still had the original slab-cut bridge. It was badly cupped (string edge toward the FB), and I replaced it with a new "German model, selected wood," $25 wholesale. Along with endpin and tailgut upgrades, the setup came out great.
12 months later, the bass still sounds awesome, but this "selected wood" bridge is curving toward the fingerboard just like the junky one! What gives?
Some other bridges for sale, up to $50, are described as "old wood," "very old wood," and "treated wood." Various "brand names" as well.
I hope someone can shed some light on the differences and tell me, how old is old, and can aging of the newer ones be reliably accelerated under controlled conditions?
Thanks,
Bob
