black Ice capacitor

I recently stumbled upon the Black Ice Overdrive capacitor. Check it out here at StewMac:Black Ice
I was going to install a TBX tone control as a master tone control, and use another tone pot for the black Ice (I guess you install it just like you would a standard capacitor). I just wanted to see if anyone had any experience with the Black Ice capacitor, and could give me some feedback on it, I have never heard it in action, and I would much rather hear it, or hear more about it (stewmac doesn't give a very detailed description).


Please contact me if you know anything about this subject. Thanks.

I've worked on several Electic guitars and everyone I'v come across has had a ' Treble cut ' tone control.
Different size capacitors will give a different range of tone control
Normally as you turn the tone pot towards bass more and more treble frequencies are shorted to ground - So yes I think the ' black ice ' would be connected the same way - Fascinating ?
Please let me know how you get on

I have earlier this year repaired a Squier and an Encore,
On both occasions both the tone controls used the same capacitor - the cap is cleverly Wired to both tone pots - however only one tone control is active at any time depending on the position of the pick up selector switch
