Gotoh 1996T

Amazing price, great quality...
Just two drawbacks...de-tuna will not fit and if you cut your guitar to work with a gotoh, you cannot replace it with ofr style...you can do it the other way around...
I have tried all three...I wouldnt have any problem with any of them...since I cannot use the de-tune on my gotoh I would get the lockmeister...
