I have one of these as well. I searched and searched for one after trying one out at a guitar show in Boston. I finally got a DOA unit. I got it to work for a while, but it wasn't reliable and clicked with the tremolo, so I have it in storage right now. You've reminded me to take it out again. I'll have to bring it to the studio tomorrow.

Roger - is the click mechanical (parts in the mechanism hitting into each other when the motor is running) - or is it coming from the signal path?

If it's mechanical you can unplug it, open it up and make sure the moving parts are aligned and out of each other's way. If someone replaced the original canister with a mercury switch, or filled the canister with the wrong fluid, that will also produce a click. That can be more involved to correct.

If it's difficult to tell what's causing it, holding and shaking the unit, without turning it on, will produce a tremolo. If it clicks then, it's probably in the signal path.

I just don't see well,  How the big rubber wheel is linked to the "other part of the mechanism ?  It look like there is a lever that goes to an shaft at the top of the casing.  And then, how the liquid filled can is connected to the "shaking" mechanism.
I'll have to concentrate more on the pictures.

This is what I understand for now.
Here is a ugly and fast done drawing :



There is two springs,  The second one, I still wonder the function of it...
If any have a clue ?

danjf

Frank - one spring (as you can guess) pulls the rubber wheel against the tapered pin. The other spring is less obvious. Turning the speed knob pushes the rubber wheel away, further towards the motor and the fat end of the tapered pin. But it only pushes it away. The second spring pulls the wheel against the knob, away from the motor so that the wheel will return when the speed knob is turned in the other direction.

If this description is difficult to follow, I can possibly post a photograph.

Wow !  Thanks a lot Dan !!!  Really kind of yours.
For your previous question: I live in Montreal, Canada.

I must do a "DIY prototype" soon after I finish to store guitar making wood.
Now the garage is a real mess.
If you have time and will to take a few more shots, it would be really appreciated.
Otherwise, I am going to try to be as close as possible myself.

Did not find it on sale.
But I still want my jazz classes so...

Thanks again !
