hi,

i just recieved my new Ibanez bass. it is a verry nice sounding and looking instrument.

But the notes on the tickest string (C in my case) sound prety dull and i gues is the effect of the down tuning + too thin gauge + maybe old strings, installed in 2013 in factory and never changed by the guys from the store.
I am wondering what string gauges can i use on the SR4000 ? my tuning is down tuned all the strings by 1 tone, and then drop the first by another tone (C G C F).
What are the thickest strings i can put trough this nut and bridge ?
What are the gauges of the factory strings ?
Where can i find a wiring diagram for this bass ? on the ibanez website, i cant find anny bass wiring diagram made after 2008...

Hello,

I can help answer some of your questions regarding this SR4000E.

The String gauges from the factory are .045 .065 .085 .105. I'm not sure what the thickest strings you could use are, but I'd assume that most bass strings you find will probably be OK after the truss rod is adjusted. If you do change to a higher gauge, you will need to have the nut filed to accommodate a thicker string.

The wiring diagram can be found here:

Hope this helps,

thanks Bill. That was really helpful.

I have another problem now :(
Sometimes the preamp behaviour is verry odd. The bass pot is completly dead. no gain and no atenuation can be observed in the output, and it sounds like the bass would be at the minimum value. only the mid and treble pots make a difference in the output sound. If I switch the preamp off, the sound is back to normal.
The batteries are brand new.
I am allmost sure there is something wrong with the preamp.
Did anybody had similar issues ?
Are there other preamps i can install without changing the pickups and pots ?

Anny help would be useful.
Thanks
Bill@Ibanez

Hmmm.. It could be something internal in the preamp if all the wiring is correct and you are still getting a problem. The preamp can be purchased as a whole, this comes with the pots and board. However, there are 2 versions. One that comes with sold shaft volume and balance pots, and one that uses the splined shaft. Which knobs does your SR have?


If your bass does NOT have a white indicator on your volume pot, you'll need:
3EQ3PC0001

If your volume pot DOES have that white indicator, you'll want this one:
3EQ3PGB002

i does not have the dots.
I found out that if i remove the battery and put them back in the problem is gone.
Could be that some capacitor in the preamp remained charged.
Does Ibanez provide the schematics of the PCB ? It could be some design flaw wich could be easy fixable if i knew the schematics

I'm not familiar with the innards of this model, are the batteries in the same compartment as the electronics? If so, just unplugging and plugging in the batteries may have inadvertently shifted a wire or some other component that was shorting against something else (a pot lug touching the ground shield would be my first guess).

If the batteries are in a separate compartment, then maybe not, although just tugging on the wires may have been enough the shift something.

Ibanez does not provide the schematics to the PCB at all, so I don't think it will be something you can fix on the board level. I agree with Abner about shifting wires. In case it help, here is the info on the EQ for that bass:

Part #: 3EQ3PC0001
