It's been a strange NJ winter season, that's for sure. I gig a lot, so my basses are always being subjected to climate changes, regardless of the season. They don't really change too much, but the one thing I have noticed is that the natural wood basses (unpainted) have some fret sprout this winter ....
I usually leave them alone for a bit and see if things settle back down. It seems like my FBB 7 is going to require a minor fret dressing, but I figure I'll wait a few weeks until the temperature moderates a bit.
IMO, part of the bass playing routine is to regularly check my set-up and make minor adjustments when needed, usually once a month or so. It only takes a few minutes to set everything back in proper order .....
edit: BTW, you Shore area guys should give some thought to the
GTG scheduled for May 20th
