Jem high pass filter question

I have read on other posts that the Jem 7vwh has a high pass filter that is always on. I know that it is only supposed to affect the tone when you turn the volume knob down, But my question is if I remove this from mine would it help warm up the sound of the guitar. The 7vwh just seems a little too bright I wish it was a little warmer sounding. let me know what you guys think and if I decide to do this what do I need to remove?
Any feedback would be helpful

I'm not sure about a HP filter in the Jems...If you're looking for a warmer sound, try sticking a PAF-pro in there.

I love the Evolution bridge pickup, but i keep a PAF in the neck position of both my guitars. It's easy enough to make it work with a halfway decent pre-amp/EQ.

the High Pass Filter only works when you turn your volume down. If you want to turn your volume down and have it warm up...then yes...replace the pot...if you just want a warmer sound in general get some new pickups or mess with your EQ a bit.

How hard is it to install a high pass filter like in Jems to a RG?
What do I have to do?

its just a little resistor/capacitor (whichever it is) on the volume pot thats soldered inline. no biggie. it just allows the high end to remain when the volume is turned down, as opposed to getting all muffled and muddy. you can achieve pretty much the same tone as removing it by simply turning down your tone control.

Here is a schematic from an Ibanez support page Eddie pointed me to
when I had questions about the Previous Owner of my JS guitar mucking
with the wiring.

The capaciter in question is the one marked 331.

As you roll the volume down, generally your treble gets choaked. The
cap bypass allows the treble to get through as the volume gets rolled
down, tricking your ears into thinking it's a more fuller sound.

It's an easy and cheap mod. A typical cap is anywhere from 3 cents to
25 cents. On the other hand, super duper high end gold plated in your
face build a $25,000 tube amp caps can cost from $5-$500. On a guitar,
with the cheap assed cables and noisy amps we love, I hardly think
you would notice the difference.

There is a LOT of magic that can be done by modding the electronics on
your guitar. But honestly, the easiest way to get a better sound, is to
practice, practice, practice.
