work. I want to put a tone Q into a Les Paul neck pickup. What
should I expect from the tone Q, or the other filters?

I can only tell you about the Tone L Filter. It's an inductor that can be used between hot and earth direct or with a series .02/.01 cap. An inductor basically drains off (filters) the midrange, leaving top/bottom only. The cap is a means of controlling the extent of the drain off/filtering. I ran this on my Les Paul for years with the .01uf cap. It did give a hollow Jazzy tone when set between 3-4 on the tone. I had one tone as a master treble cut (as normal on Les Paul's but for both PU's on mine) and one tone control as the midrange cut (Tone L Filter). The filter can take away all the bite if not matched via cap and knob setting.
Where did you hear about these filters as I am also looking for more info.

A Q-filter and an L-filter were just removed from my LP Deluxe. Guitar sounded great with them, haven't yet heard it without them.
