Yesterday I bought an amazing bass guitar - a used Fender Jazz bass with active electronics. There's a little switch to toggle between passive and active. However, only the active mode is working. I've already checked the batteries It appears to be a bad PCB. This is the PCB that holds all potentiometers, the pickups plug into this PCB and the PCB has a little OP amp on it (a dual OP Amp TL072). Any idea what a replacement PCB would cost?

Active mode use the PCB, if active work, is not a PCB issue.
I don't now if Fender sell PCB.

I've got the Fender American Elite Jazz bass. I'm pretty sure it's the PCB - I ran tests. However, the music store that I bought this bass from is supporting me by having their tech look at this - and since the bass was advertised as 100% working I'm sure they will fix whatever the issue may be at no cost.

This is the PCB:

Thanks for the links.

If Active mode work and not Passive issue could be the small toggle Switch ?

Good luck. Report what store do.

You did not test Bass in store before return home ?

I visually inspected the bass at the store, but I didn't test, or plug the bass into an amplifier while at the store - which would have made everything much easier. But, on the other hand - how often does an instrument have an electrical fault that wasn't easy to diagnose and fix within a few minutes? The symptom of no sound from an electric instrument is unusual to begin with. But, sadly, in this case, it appears to be an intermittent connection on the PCB active/passive preamp itself. =(

You leave the Bass at store for repair ?
Sometimes bass work fine ? The small toggle switch may have broken solder on PCB or the switch itself is the issue ?

Yes, I brought the bass guitar back to the store the day after I bought it. Passive mode never had sound - for me at least. I just got an email from the tech and he tells me that a new PCB will be needed to repair this bass guitar.

Great, I hope you do not have to wait one months.

It might take a couple of weeks to order a new PCB - maybe a bit longer being that this is a holiday week. The tech said I could take the bass home with me while waiting on parts.

They've had that bass guitar for over a month and never ordered the part. I'm very disappointed with them. I may need to drag Reverb into this.

It is with a heavy heart for me to say that I'm very unhappy with the musical instrument store that sold me this bass guitar. In the past, I've always liked them and always recommended them to friends. However, the bad taste that I'm left with over the purchase of a non-function bass guitar that cost me $1500 may force me to end this relationship and force me to not recommend them to anyone anymore.
