I attached a battop to my SE a few years ago and it was an incredibly simple and straight forward process, as far as I can remember I just held the stick in place and twisted the ball top off and added the battop.
I decided to switch back to battop on my TE because I thought it would be more comfortable as I have large hands but after holding the stick in place and rotating the balltop it just spins round not getting any looser or tighter.
Does this mean TE’s are different to SE’s in this regard and that I’ll have to go searching for my tool kit, or is this a defect?
