>>>Love to work with the servomotor, so It won't be as akward as using vibrators as I have been doing for the past few years.
In all seriousness, haha, you mean...vibrator as in...?
yep. multi-speed vibrators are great to work with junk metal, springs, etc.
same concept of the servomotor, but easier to manage. I buy cheap ones from red-light district vending machines, and destroy them.
still have a big one bought in Paris many years ago.
live-wise, I always put a small one connected to metallic part and effects and leave them be for the whole gig.
>>>Is the reverb natural (not including the echo) in the 3rd recording?
yep, result of the springs
will record more complex stuff tomorrow and try to post a video. I have several weird spring based instruments that are perfect for this use
