Dimarzio Evolution on RG

[zagor256]

HI,

I bought Dimarzio Evolution pickups a few days ago to change old powersound pickups.
Should I change only pickups or also some ports on electronics.
I noticed the there is some different parts:

On RG guitar:

POTENTIOMETER (VOLUME) 3VR1J500G - linear
POTENTIOMETER (TONE) 3VR1J500D - log

On Jem guitar:
POTENTIOMETER (VOLUME) 3VR1C500B
POTENTIOMETER (TONE) 3VR1C500D

What is the difference between potentiometers?
Is better to use log volume potentiometer and linear tone potentiometer?

Anyone?

Please just answer this:
Should I change linear volume pod with audio(log)?

I don't know enough to give any real help, but when I put Evos in my RG620 (replacing V7/ I didn't change the pots and it sounds fine to me

Wow, I must have overlooked this one, Basically the only time i change pots is if i get a crackly or broken one, I'd just wire up and leave the pots in there

Generally, the human ear can only detect volume changes logarithmically. But the basic question is this: can you hear the volume change across the full range of the pot (1 to 10)? If you like the way it works now, I would just swap out the pickups and leave the controls alone.

I just wrote this because I read a review at harmony central, and one of users said:
"One piece of advice though, for some reason Ibanez is installing linear taper volume pots in their guitars. This is basically a no no so I have no idea why they are doing it. My advice would be to get an audio taper 500k volume pot and install it when you install your new pickup. This will allow all of the signal to come through. I learned this lesson the hard way. (I ended up shipping a Super 3 back to Dimarzio and exchanging it for a different pickup when there actually wasn't anything wrong with the pickup in the first place, the volume pot was just sucking signal)"

And also Dimarzio support mailed to me: "I don't think linear pots are suitable for high gain pickups (volume and tone)?"

Anyway I changed pickups and add only 300pF capacitor on volume control (treble compensation) and guitar works fantastic.

Thank you all.

Log pots pwn harder. I just put Evos in my Rg1570 without changing the pots and it sounds great.

You know, it just depends on the sound you want. Changing your pots to audio taper will make it sound very bright. Disconnecting the tone pots changes the sound too. There's lots of variables in tone changes. If you think that sending the Super 3 back, because you didn't like the sound..chances are with the tone pot changes you made..you probably still won't like the sound of the Super 3. It'll only make it sound brighter with a little bit more output. The characteristics of the Super 3 would basically be the same.

Not saying Dimarzio support is wrong about the linear pots not suitable for high gain pickups, but wouldn't you think they're saying that so you could buy their audio taper Dimarzio pots? lol
