Now that the topic has moved to amps:
I've had a "spare" JBL D123 12-inch speaker sitting around for over 20-years. I'd often read from Harvey Gerst (father of the "F" series JBLs for Fender) about what a wonderful guitar speaker it was so I picked up a Fender Deluxe 112 locally from Craig's List for a C-note and one day when my daughter's boyfriend (an accomplished classical bass player, guitar player, and recording artist) was visiting, I installed the JBL in the Fender. After a few minutes of playing his guitar through it, the transplant was confirmed as an excellent result! Cheap thrills!
Later, I found, purchased, and had my daughter pick up in NJ another perfect old D123 for them to use in their own gear. Maybe we'll hear it on their next album.
