Let's say hypothetically I wanted to string up a SE with 13s (including a wound 3rd string) and tune it B to B. What are my options as far as adjustable bridges? So far I've come up with the following: 1) PRS adjustable bridge. That would work, yes. But they cost $290. The guitar I'm looking at buying costs $300 used... for the whole guitar. 2) Schroeder? 3) Pigtail? 4) Hipshot Baby Grand? 5) Others? Or should I wait for the new SE Clint Lowery?
