While I'm still waiting for a luthier quote (actually, it's not THAT long, it just SEEMS that long!) I have a question that I'm not currently equipped to answer.
Tim advised me on pickups to get a single coil sound in HB size routs, (MQs) but said (wisely) that if yer wants single coils, then that's what yer needs.
While I'm waiting, it occurred to me that I could try an experiment with, say Irish Tours to listen to the "offset" in a couple of my guitars with whose characteristics I am very familiar. (No smutty jokes please).
Can you suspend a strat type single coil from a standard HB ring or is it dimensionally impossible?
Sorry if everyone laughs me to scorn, but I ain't not got none ter try.
