EVH d-tuna

Hello all. Its been a while. I recently purchased an EVH D-tuna cos this would be cheaper another floyd rose guitarmand tune it to drop d.
The packaging with Eddie on it got me excited. The device itself looks deceptivley simple. A long screw, spring, a skinny hex wrench and the device itself. However, it is not tremolo friendly so i had to stabilise my floyd rose by either blocking it or get a stabiliser. Since tremolo stabilisers are hard to come by ay this side of the world, i blocked mine so no pull-ups, just bending strings.

I blocked mine with slicing up old credit cards and sticking them up with tape with a rubber stop due to the irregular shape in the tremolo cavity. It is working but ill need to get a harder block so that the shape will not change.
After this we can get into installing the D-tuna proper. Just follow the instructions included. Unscrew the low e string saddle and remo e the tuning screw. Assemble the d-tuna device by sliding the spring on the screw and sliding the d-tuna device on the spring assembly. Next, screw the d-tuna assembly on to the low e-string saddle.
I would have thought that was it but found that i could not slide the d-tuna all the way in. That is where the hex tuner comes into play. So, you’ll need to screw the fine tuner all the way out, tune the E string to D then engage the d- tuna and une it to e using the hex wrench. Operating it is easy. Push the d-tuna in for E. Pull d-tuna out for D. Enjoy.
