rotating speaker cabinet

i really like the sound of tremolo, and i like building analog devices... when searching around the internet a quite a while back i came across what was called a " fender vibratone cabinet" which is a rotating speaker cabinet designed for guitarists to use for tremolo as you would with an old hammond leslie cabinet with an organ.  the difference here was that this version had a cross over in it to separate the high/low and mid frequencies from each other. when actively set up it send the high and lows to the cabinet while the mid frequencies keep coming from your amp. i decided i needed to have one. or at least try one out. there was a slight problem in the fact that i could not find one... turns out they are rare. so after months of research looking at schematics i figured out how to build one with some old parts and crafty skills. and this things just flat out sounds amazing. heres mine finished.
i decided that i would actually build these for people who really want them. so if you are interested in one let me know and you can come and play mine and see what you think. they take awhile to build 3-4 weeks. but the wait is totally worth it. it really is a very musical cabinet and has such a wild 3 dimensional sound. cab is solid pine. and the baffle is 5/8ths ply. the motor has two selectable speeds. slow and fast.  just like an organ tremolo. it can handle any 100 watt amp, but works best with old tweeds  or really anything in the 40 watt range.
