All good points and no offence at all taken. First let me explain the arm rotation, that came as a matter of necessity. A year ago I discovered with the first prototype that it took a crazy amount of effort to pull up on the arm. I was trying to raise as many notes as possible within the limits of what strings are capable of. In order to retain the pull up method I would have had to do a gear reduction (or cam) and the arm would have had to move out approaching 90 degrees. I had to have a certain range of motion in order to spread the effort over. So until a few months ago I was scratching my head wondering what to do. Then I had the light bulb moment and thought lets rotate this. I predict you will see other tremolo makers follow this in the future, one reason being is that it is a natural feeling movement. I plan in the future to develop an optional clockwise rotation for diving.
My original thinking on developing a new type of tremolo was that I would make no comprises on function so I didn't bother with making it installation friendly. Honestly with this design it would be tough to make it smaller and it definitively would be a compromise. These are the things I was not going to compromise on:
1: Tuning stability, changing string gauges or drop/raise tuning has no effect on it.
2: No string lowering when going up on string tension, made for optimal string action setup.
3: Raise multiple notes, strings being the only limitation.
4: Idiot proof once it's installed, easy to use change strings, doesn't need tweaking
I have had a few guitarist play with it, the first reaction is wow this is cool being able to raise notes like this. I am going to get a pro to make a demo video at some point, got to write the riffs for this thing first lol. So far the most interest expressed has been from the country music players, who knows what genre will find it most useful. The tone is different, very distinct. I am sure that will bring out some love/hate for it.
