Treble Bleed (331 Capacitor)

Looking ate new features on the new Pia, noticed that Steve Vai dont use the treble bleed when he is using overdrive on his guitars. That push/pull turns the high pass filter on/off and he uses only when he wants to clean the sound.

I got my 1st Jem this month and noticed that I had to push the bass a lot to find the sound I like. Thinking to myself I noticed that the only difference of my guitars is this detail.

Does this capacitor cuts off the low freq even when it's on 10?

Please help.

Re: Treble Bleed (331 Capacitor)

When the pot is on 10, the capacitor isn't doing anything. (this is a highly argued topic on forums; if you measured it with a meter, you would SEE the cap IS likely adding a HAIR of capacitance, but most of the population agrees it's not something you can HEAR.) So- short answer- no, when the pot is on 10, the capacitor isn't doing anything you can hear. If the JEM lacks bass to your ear, that's the pickups/guitar itself.

Because sometimes, I would imagine, he wants to be able to turn down WITHOUT using the effect the capacitor has... meaning, it's not just an on/off... when he's clean, he wants to turn down WITH the capacitors' effect, when he's distorted he wants to turn down WITHOUT the capacitors effect. So, push-pull.

I think he borrowed it from the JS's that he has. He's always had active high pass filter at all times, now it's an option using the PP pot. That's the way Joe has always used it.

Evo has this system too, he had the guy from Mad Hatter install it a few years back. The PIA system probably isn't solderless like on EVO though.

Actually, Evo already had a regular push/pull vol pot with highpass filter on/off before Madhatter installed the solderless system, which in my opinion and experience with that system not worth the money.. snakeoil..
