I have a Fender HM that I would like more tonal options. It has a 5 way controlling 3 J pickups. I would like a volume and tone for each pickup, but don't want to mod the body. My idea would be pickups>triple stack volume pot>triple stack tone pot>leave 5 way in as a kill switch so I wouldn't have to touch the settings. My search has yet to find a triple stack. I think this may be a fruitless search. And, if I find them they may be too deep. Has anyone ever seen one?
