The factory controls on my SZ consist of 2 volume knobs and 1 tone knob. I'd like to modify it so that it has 1 master volume and 2 tone controls, 1 for each pickup. Is this doable? Is it a good idea? Are tone pots and volume pots the same or should I buy a new tone specific pot? I've seen a few diagrams on splitting coils and such, but I haven't seen one that shows this. Has anyone done this before? I'm wondering if anyone can point me in the right direction so I can figure out how to do this. Any advice would be appreciated!
Also, at the same time I'd like to set it up so that both pickups are fully on, not coil split in the middle position. I've seen a few posts on this before, but I don't know if anything changes based on what I'm doing above?
Thanks in advance for your help people!

1. save up money
2. go to sherwood music
3. tell mike in setup your problem/modification
4. pay them to fix it
5. ???????????????????????
6. PROFIT

that's what I would do . . .and the SZ part of the forum doesn't move as quick as other sections but someone who knows will eventually come along and post something much more constructive than I did

I've never done this - but it would not be very difficult. Actually it would be significantly simpler than the OEM wiring. The only thing close to a complication would be the OEM 12-pole pickup selector switch - which can be replaced with a standard switch if for no other reason than to simplify the project.

I would recommend replacing at least the volume pot that you want to turn into a tone control. Again, just to make the project easier for you.

Once you do this conversion, if you wire it correctly, the tapped sound in the center toggle position will go away.

well the volume controls are linear tapered and the tone is audio tapered
meaning the "swapped to tone" volume pot would act differently than the other tone control

you could swap the existing tone to the master volume and then both volumes to tones

but then both the tones would act in an unexpected way


either way


you will have to move the input jack from the tone control to the master volume
[blue and green wires]
( whichever wire is on the ground of the tone control need to remain on ground when you move them and the one represented by the blue line needs to go to the outside terminal that is NOT connected to ground )

take the two wires off the neck volume and solder them together and cover with tape
(fat grey connection)

take the same two wires off the bridge volume and solder and tape those as well

(red)

from the center terminal of the master volume
follow the black line to the bottom middle terminal on the switch
solder to the middle bottom terminal and jumper it to the middle terminal just above it
( needs to contact bot in order for both pickups to work )




from your old master tone/new bridge tone control
follow the purple line to the bridge pickup selection
( bottom left corner of the switch )

on your old bridge volume/new neck tone control
you will have to unsolder the "one terminal to ground"
you will have to get a capacitor like the one at the black arrow
and duplicate it at the orange arrow

one leg of the cap to the center terminal of the pot
one leg to ground( be careful not to let the legs short either of the terminals )

then follow the purple line to the right side of the switch for the neck pickup selection


make sure each pot has a ground connection from the back of each pot over to the volume

I am curious as to what changes in tone control was gained by changing the controls to two tones with one master volume.
It is like a strat. Somehow this makes sense, but I would like to hear about the outcome. I too am not extremely happy with the factory setup. I was considering just making the coil closes to the neck hot, instead of the middle coil.
I see that you were interested in making all four coils hot. How did it turn out?

Dance I'm thinking about doing several things to my Ibanez 520 SZ. I would like some feedback on these options, particularly from players that have done all or part of what I am thinking of. Folks can email me direct.
1) I too want to wire the guitar with one master volume and two tones. I do not like the factory set-up....two tones would (I think) give more tonal control and balance over the two humbuckers.
2) I am going to change all three POTS to be Audio Taper Pots....again better control. Either CTS or Bourne POTS.
Each POT will be 500K and the one tone (neck) will have a .01uF capacitor, the bridge tone will have a .047uF capacitor.
OR.....has anyone tried the "Stellartone Tonestyler" Tone pots....they are 12 position tone pots. Check out the web site or Guitar Worlds product evaluation.
3) Since this guitar has a think mahogany body with strings through the body (incredible sustain), but it is VERY warm, especially with the stock middle toggle setting. I am thinking about changing the 3-way stock toggle to a Schecter 5-way (similar to a C-1 Classic). This is to help with that near thick sound because the inner coils can be wired parallel...to get a single coil sound.
4) The stock Duncan/Ibanez pick-ups are ok.....but I'm thinking upgrade....but could use some suggestions here.

If anyone can provide some thoughts on this project, links to wiring diagrams, experience on what any of the above changes would do....it would be greatly appreciated. Think

hello Ric

1)
ok fair enough sounds like a preference thing
the diagram above should help with that

2)
pots all audio? cool
only caveat would be that the CTS come with a slightly larger diameter threaded shaft
and you may need to open the holes a bit to 3/8 inch
not hard just be prepared
also when putting capacitors on
be careful that the legs don't short to ground before the capacitor


3) your pickup selector switch
its the Toggle style right?
like this

and you want to swap that with a 5 way blade?

I am not familiar with a 5 way switch that would drop in with out some body modifications


4)
I put the Seymour Duncan Hot rodded set in my RG2
these cover the classic 70's rock well
and with the right pedals do the 80's hair band too
and I put the Carvin S22 covered pickups in my RG4
heck I just loved the look of the no holes chrome covered pickups
the 11 poles per coil eliminated the F-spaced vs traditional spaced debate
they are warmer and sound decent split
but not single coil at all like the SD pickups do
the style of music you play will play a much bigger part in which pickups you exchange them with
if at all
( those Duncans should be replicas of something in the standard Duncan line )
if you could post the resistance reading it may shed light on which ones

to take a resistance reading
with an multimeter set to ohms

plug the guitar cable in to the jack
select the neck pickup with the selector switch
turn volume all the way up
on the other end of the guitar cable
one lead to the tip
one lead to the sleeve or part just below the black ring of the jack
should read something like 7.5K or 8.5K ohms

repeat for the bridge and and post results
or just got to the SD site and compare the resistance with their standard line
that should narrow it down a bit

IIRC the duncan/ibz pickups in the sz are based off of a jazz neck/distortion bridge . . . someone opened up their sz on this forum and that's what I remember of that thread
