I played in Glasgow with my band last Friday night,in a place called Rockers.....it was freezing cold outside,and my guitar had been in my home office all day(wee room with rubbish,dvds etc) I put it in a soft gig bag,out into my van for the 30 minute drive to Glasgow,then into the band room of the venue......After about an hour,I tuned it and then we sound checked.....it was well out on a couple of strings......I might have bumped into something on the stage,as its a bit compact and we are a 5 piece band....
After the sound check,I tuned it and checked it a couple of times.....I have a small Korg tuner,with the built in mike.....It seemed to be picking up everysound in the venue,so I used the guitar players tuner on his zoom pedal..... When we started to play...it was out of tune again.....I wished the stage would open up and swallow me......I tuned it during the song,but everybody in the bloody place noticed!........Something to do with the hot,then cold,then hot situation maybe!.....its a Tokai Jazz sound bass,never had any tuning issues before.....though the strings were a couple of weeks old...so maybe not played in yet!...any one else had this trouble?
