A friend of mine recently acquired a 1935 B6 (nothing to do with Ray's collection or the current ones on eBay). When the volume control is turned up about half way the tone changes dramatically to a high pitch. It's not scratchy like a dirty slider. There is no tone control on the 1935 models. What are some thoughts on this problem please

My own c.1935 single knob Bakelite does the same thing. I posted a similar question and got this reply from the "guru"...

As far as the "sound" associated with the wiring scheme ... The one knob Ricky's were wired in a rheostat fashion.
Two hot and two grounds came from the coil ... One set went to the potentiometer ( usually with one of the three lugs removed) ... And the other set going to the jack.
This made the volume a "variable load" control ... As the volume knob is rolled back, the load on the coil changes ... Altering the tone ... Kinda a one trick pony, but quite effective when no tone control is used.

On my guitar there is a sweet spot between the extremes of bass and harsh treble right before the bump in volume which is where I keep it. |

Some of the early Rics had a large Centralab(I think)pot with a design unlike the common carbon-track type we are used to where a felt tab presses a flexible steel ring against the outside wall to vary the resistance. These sometimes get dirty or even seize up and can be disassembled, cleaned and lubed and returned to proper operation. Maybe that would help to improve the response and make it more even.
