I explored the Varitone at great length for a trashed slot head EBO I restored to an EB3 configuration, but I couldn't find a version worth playing. What little character the EB3 pup has is not to my liking. The EBO is great but doesn't blend well.

It occurred to me the 30K Ohms of the EBO is four times the 7500 Ohms of a Custom Shop 60's JB. By splitting the coils of the EBO, a parallel mix sets both pups to 7500 Ohms. A push-pull switch switches the EBO to parallel or series mix and a second push-pull reverses the polarity of the JB. The Varitone rotary switch allows all mixing possibilities. I made identical mounting plates for the JB and EB3, so the modification doesn't make visible changes to the EB3 configuration. I use the pots on the push-pulls to allow separate tone for each pup

Not only is the tonal range incredible, it mixes two of the most recognized sounds going in some very interesting ways

I 'll send a schematic to anyone interested.

Sometime later I realise but if you still have that schematic I'm most interested.

Hello all,

I'm an eternal amateur. Longtime guitarist, I began timidly exploring bass a few years ago after a foray into modular synthesis. The last few years I've been playing on a Westone Thunder II and an Epiphone Thunderbird with Gibson pickups. Love these two basses! Just recently picked up a Lace Helix because the opportunity knocked and I was intrigued. Lastly, I have an Epi EB3 which I bought about ten years ago and which I still enjoy playing. 

I live in Brittany. In self-imposed exile from the USA (The Clash song really hit home with me).
