Ordered this for my 2014 Gibson SG (with the smaller pickguard). Initially it didn't fit due to it rubbing against the bridge pickup ring. After I filed-down the pickup ring it moved freely, but then I struggled to get the trem low enough (an action of 1.8 on the high E string was the best I could achieve, which is not ideal!). I therefore took the decision to cut the pickguard so the trem could sit flush on the body. It was at this point that I realised there was a bracket in the centre (where the push rod rests) that had dented my guitar body. I also realised that to get the tremelo any lower I was going go have to drill/cut an indentation (approx. 1cmx1cm) for this bracket to go. As the guitar was already damaged in this location I decided to go for it and drill the hole. Once reinstalled I managed to get the tremelo lower and achieve an action of 1.3 on the high E (much better!). However, much to my intense frustration, I now noticed that the tremelo didn't return to a consistent position. There were no binding issues etc, I think the push rod wasn't perfectly centre in the rear bracket and was rubbing against the casing.
It is also worth noting that the trem arm has an annoying indentation, which means it will be very loose when pushed in. You can tighten with an Allen key, but then would need to untighten to remove. No idea why they didn't just use a normal trem arm. I did try another trem arm, but the dimensions are awkward with this tremelo (the arm that comes with it is shorter and has a bigger bend angle).
Also worth noting there is a significant chunk of metal either side of the bridge saddles, which is pretty annoying...
It is now on its way back to Thomann for a replacement (Thomann have been great throughout the whole process and have offered to refund/replace etc). As I have now committed to the modification, I'm sticking with it, but I might warn others not to bother. I do have hope it will be awesome, once finished, though, but it is certainly not a 'drop-in' modification.
