Hi Leon ,glad to hear your strats still working ha ha ,hope you are enjoying the sound of a strat bridge pickup with the tone rolled back some. yes the cap that keeps your tone bright ,very usefull ,i have an on/off toggle switch between the cap and volume pot on most of my guitars because it can be annoying keeping the guitar bright all the time when you turn down ,sometimes its nice to turn the guitar down and the tone gets duller like it`s suposed to especially when playing da blues but yes a nice option to have .
