OK, so I’ve been drooling over rotary speaker cabinets recently. I’ve really been wanting that 3D, rotary pulse sound. Think Leslie speakers. Think Stevie Ray Vaughn. Think Booker T and the MG’s. That sound.
Leslies are usually vastly expensive, however. But what’s this? I found a guy who wanted to sell his Little Lanilei rotary speaker cabinet for a very small amount of money. Awesome!
So I just got it today, and it kinda sucks. The rotating cone is cheap and poorly designed, so the tremolo effect is not very clean, deep, or pronounced. And it takes FOREVER for it to spin up to speed, and then stop again. Unacceptable. Hell, half the fun in a rotary sound is being able to change tremolo speeds on the fly, or stop them suddenly.
But I don’t think I’m going to be able to send it back. So I was thinking, why not make it a project? Make it rule.
So I want to redesign the cone. Not a huge deal. I can do that out of a cylinder of styrofoam and a sharp knife. I’m SURE I can make a better cone than the thin, chintzy one they made.
But here’s the problem: I don’t know much about small electric motors. But I kinda know what I want. I want a small (probably 9V) electric motor that runs at low speeds (I don’t want to spin a propeller. I just want to spin the cone at up to a few hundred RPMs. I also need it to have adjustable speed, and (important, I think) higher torque. I need it to be able to start and stop much faster, and change speeds fairly promptly.
So you engineers and guitar/organ/Leslie folks: ever taken something like this on? Are there any good sources for small electric motors that would fit my needs? Any ideas?
