Why is it I always seem to upload after the clever guys! have posted! ah! well!
Anyway! This guitar is only a few weeks old and the chap wanted some additional pulls and changes to the set-up so I got lucky and have had it for a few days sadly it goes back tomorrow!
First Sierra I've had my hands on.... beautifully made instrument! with impressive sustain! IMHO!
Hi Chuck, It does a bit eh!
The answer is that the floor is slightly uneven and had I adjusted the back legs to suit it more accurately there would have been no movement! I must be more careful in future!
ah! well!
