I was playing with the Purple mess trying to get things to work. I have a tuner for it now....have had the neck adjusted.....but the action is super high and the bridge is way down.....anyway. When trying to tune it, the lead bag for the PBH-4 was closest...so being the lazy man I grabbed the lead from the bag.....look what I found inside with the 2 x allen keys.
Hmmmm....I thought....maybe that bottom of the truss rod is able to be left out....or tapped in. Allen key access if tapped in....and the steel pin if it is out. I can imagine that the pin would give a little better access. So I used the pin and the truss rod end just popped back out easily and the pin fits straight in.
Interesting.....wokka have a look in the lead bag that came with yours.
