I did some searches and I couldn't quite find a tread that addressed this issue exactly - I am starting to learn slap style on my double bass. Its fun as heck, but it won't be my main style in the forseeable future. Here's the thing - I have been informed that getting bridge adjusters will really help me be able to get under the strings without moving my hand too far towards the bridge. Here's the question - can I adjust 'em easily on the fly? Like between two songs in the time it wouldn take to tune? Or do I need to loosen all the strings or something before lowering/raising the bridge? Second question: Has anyone had 'em installed recently by a luthier? How much can I expect to pay for a fairly "standard" set of adjusters installed? Third question: Is it true that rockabilly type slapping sounds best with gut strings or a solo set tuned to normal (EADG) tuning? I know this is a lot of questions, if anyone can help me with any of 'em, I'd be tickled pink.
