    yeah, my covers worked fine minus the trimming of base

    you can get a 500k pretty much on every guitar or music instrument store, or even ebay. it's pretty much a standard guitar accessory like strings or plectrums ;)

    i can't tell you if you can use the EQ switch without knowing what components it is made of. my guess is that it's an active EQ filter, which means it needs a battery and is probably designed to work with active (buffered) pickups. from what i've heard, this EQ switch seems to be pretty unpopular anyway :lol:

    i would personally remove the EQ switch and install a tone knob, which is way more useful imo :)

    Some metals don't contain magnetic properties (Zinc/alloys, aluminum, etc.) but I wouldn't chance it to find out. Look at the old Gibson PAF's, there is a shining example.

    Sounds fine... so where did you get your pots from? I don't want to get the wrong style of pot. I see so many different styles?

    i'm in germany, dude ;)

    here's what you need:

    STEWMAC.COM : Alpha Control Pots

    or this:

    STEWMAC.COM : CTS Control Pots

    both are good brands. i would go with the 500k CTS split shaft, personally

    i think gibson covers are made of nickel, which is magnetic. Not sure what they used in the old days, though.

    Thanks immensely for all of the assistance Loktide. I bought an original knob from Ibanez ($19 shipped, sheesh) and the 500K CTS long split shafts. I wasn't sure if it used the standard or longs, but after I pulled it? It appeared to be a long shaft. Thanks again for all of your help!

    Well, mine arrived today, so you can probably figure out the timeline from when i ordered to when they arrived. They were shipped a week ago, so it did take them a while to make it across the atlantic!

    I know I know, but basically the EMG808's aren't the easiest to sell, so I figured I may as well sell them if i got the chance and I did. Pickupless guitar :/ Bum.

    Anyway, now I am just waiting for the pickups.

    Oh, one bad thing I have just noticed is that I know I will probably have to saw some of the bottom off, but I don't have a way of knowing how tall the EMG808's where, r does this not matter and is it more a case of making sure the pickup sits flush up against the top of the plastic cover?

    OK, basically I got mine 15 days after ordering, including a week of them sitting in the post.

    haha, i had understood that you had sold forward the pickups you're now waiting for in the mail :lol: now it makes sense

    sawing the bottom off was just to get the pickups as close to the strings as possible. imagine having a 5mm gap between the pickup and the inside of the cover plus the 1-2mm cover thickness. you would have to set the covers way too close to the strings to get the pickups adjusted and they would probably still be too low.

    Haha goddamnit, I am stupid! I ordered CTS long split-shaft pots, and they are too big and wide for the holes; I am assuming you have to use Alpha pots @ 6mm versus the CTS @ 1/4", and I... just don't know what the hell to do about this. Can anyone clarify what pots exactly to use from Stewmac since I am a complete crayon muncher at this shit?[​IMG]
