Last month, my wife, the 2 dogs and I moved to a new home. The day before the move I packed all of my basses into the hard cases and gig bags (a couple of which are double bags) that I have and transported them to the new home myself. They were placed in my new media/music room and remained in their cases for about a month. After about 2 weeks, I grabbed my Squier VM Jazz bass and put it on a stand in my living room. I did this so I would play a bit each day. I noticed when I got the bass out, the action was nice a low and played great. Bonus! I also grabbed a random gig bag for rehearsal 2 weeks ago. Inside it was my Sterling by Musicman Ray34. The setup was good, but it was about 1/2 step flat. I tuned it up (which caused the action to not be as low) and it did fine in rehearsal. Fast forward to Monday and I start getting the new media/music room organized. Up until then, the room and rest of my basses were untouched. On Tuesday morning, I unpack my basses. I placed the basses on the same rack that they've been on for years. Tuesday evening (yesterday), I decide to plug in one of my basses and see how the acoustics are in the new space. Bass #1 (Cort A5), string action SUPER low, buzzing on the first few frets. Bass #2 (G&L L2500), same thing. Bass #3 (Lakland 44-01), adjusted fine and playable, but MAJOR fret sprout along the edge. The neck on #3 was Pleked years ago and has always been absolutely perfect. I have several other basses, but I didn't have time to check them all. So for basses 1 and 2, it seems there isn't enough neck relief now. For bass 3, the wood must have contracted to allow the fret ends to sprout. Sooooooooooooo, has the wood contracted for ALL of my basses? What's going on? Do I need to let the basses acclimate to the temp and humidity of the new home and acclimate to being free of the cases? I've never had basses have their setups be this far off before. I can adjust them myself, but wanted to see if it is best to leave them for a bit or can I just do it now. Potentially Relevant Information....maybe.....maybe not?? The new home, while not being way up in the mountains, is at a higher elevation than my previous home. Also, at some point during the month, I accidentally turned off the furnace for the second floor. So for a few days at most, the temp of my music room got down to near 50F. I promptly got that resolved and the upstairs has stayed a steady 65F.
