.0047 cap, 12 string?

I know the basses did, but did the guitars, specifically the 12 strings, have the .0047 in the bridge as well?

They sure did!

Sucking the life out of that jangle too!

So is the consensus that the .0047 cap made it sound worse? or better?

it would make the bridge pup more trebley, correct?

I'm not sure if the cap adds treble, or simply cuts bass. I played a '79 360/12 that was simply ridiculously trebly - a Rick of that era would have the cap, but i'm not sure if it was the cap I was hearing or the old design higain pickups.

The cap cuts bass.But something I found out by swapping out different .0047 caps is that, while they All cut bass, differences in Tolerances of a given cap can do the "sucking the life out" phenomenom.Because of, or in spite of that, some guys swear By them, others swear At them.YMMV...

Has anyone ever put a .0047 cap in on a modern 12? Or is it just not neccesary?

I haven't owned a new 'standard' model RIC in 16 years. Correct me if I am wrong but I thought all RIC's come with the third .0047 cap.

IMO, the little mix knob has always been useless. Turning that knob into a .0047 cap set up would make more sense. You could then dial as much .0047 as you would want or just dial it out completely.

I have just put a 0.0047 Sprague cap in my 2004 330x12 with higains and I just love what it has done to the sound.It has removed the ubiquitous jangle a little but now the guitar and amp seem as if they were made for each other with a dark and gritty eloquence. All the heroes had them in their guitars and they all sounded different. Get yourself some caps and step outside of the clones you wont regret it !!

The cap definitely cuts bass. The cap and the resistance in the tone pot act as a first order high pass filter (passive). Capacitors block DC and pass AC voltages. The lower in frequency you go, the closer to a DC voltage you come - So the bass frequencies below a cutoff frequency (determined by the cap's value and the pot's resistance value) decrease in output at a rate of -6dB per octave.

Great description! My Navy electronics teacher could not have said it better!
