Wouldn't gig with my acoustic without these boyos! I swore i'd never get caught again...was gigging one night, went to tune down the guitar to open tune for a steve earle number and the 6th string broke! "Right, no panic...i've loads of 6th strings...like every acoustic player!!! Upon taking the string out, the pin was giving me a hard time...wouldn't budge, so got the plyers from the gear bag and started pulling lightly on the pin, while talking sh$%te with the crowd and here the bloody pin broke! no way of supporting the string, no way of finishing the gig...ended up sticking a match in it, nightmare trying to keep the string in tune, bought these the next day and will never leave the house again with my guitar without them...
