I have a Valenti J 5-string that has an ash body and maple board, Sadowsky preamp. It's one of the most comfortable basses I've played, but boy is it bright. With steel strings it's unacceptably clicky. With nickel rounds, it's still growly enough to do the rock Geddy thing, but I play in a horn funk group. Either way, I find myself rolling off the tone control more than I want to, because that tends to pull out some of the mids that I'd prefer to keep in.
I just ordered a set of Pressurewounds to see how they tame back the high end. Based on what I read in these threads, they could be just the thing to keep this particular instrument in the roundwound ballpark but to make it a little more laid-back sounding. I'll report in.
I'm looking forward to read your thoughts on them, Will.
