I took my Tokai Jazz along to practice, I got setup there, when to play a bit and noticed the action on the g string (oo-err) was too low to play it atall at the first fret, I do play with a low action normally, but obviously not that low! I hadn't played it since last week (Thursday) and it's been in it's case since then just downstairs in the study, is humidity likely to be the problem and if I give it a quick setup it's unlikely to happen again?
Tonight I phoned my house and got someone to drop off my warwick to use instead, that was fine (but has been in its bag for weeks in my room).
