I never had a problem with my 734a as I went thru bridge.... I've never had a problem with the 1200s ever... hmmm maybe the tuning peg is not as wide as the 1200s'....
Mind you Hooky has a 45 on his high E on his six... I got it to tune to E after 4 days of stretching ... sat down to play it and it snapped, nearly chopping my fingers off. I went with 40 after that....
Yeah I noticed that string on his PMT interview... maybe he snapped it before filming???
