Hey guys I got D Tuna through this morning and installed it on my Carvin DC135. Now, when it's 'out' it's tuned to D pefectly. Now when I push it 'in' and use the fine tuning screw on the D Tuna to tune it to E, I can't pull the D tuna out. The fine tuning screw is gripping the locking screw too much and I can't pull it out at all.
Has anyone come across this before?
Is there a way to fix it?
