Bridge pickup in 4003 weak - vintage tone switch?
Hey all -
I’m doing a setup on a friend’s ‘08 4003 (fretless, to be exact), and the bridge pickup is super weak.
I have not disconnected the pickup completely from the circuit to check it on a meter, because I noticed something else too; the vintage tone push-pull knob appears to have no effect at all. That is, it works, but the treble bleed in/out doesn’t have any effect. It’s the early cube shaped version of the switch, not the later/current round shaped switch.
Before I chase my tail, I ask, should I replace the push-pull pot, or measure the pickup off the circuit?
Also, where should it be? 9k ohms ish?
Thanks folks!

Can you bypass the switch with a piece of wire to determine whether the pickup and/or the switch is/are functioning correctly, or not?

I can certainly try that. What’s my contact points for bypassing?jps wrote:Can you bypass the switch with a piece of wire to determine whether the pickup and/or the switch is/are functioning correctly, or not?

Any way you can post pics to see where to do so? What you want to do is bridge between where the cap is attached to the selector switch and the lug on the push/pull switch that is NOT the one the other end of the cap is attached to.

You just have to connect the lugs of the cap with a wire - then it is bypassed.
To measure the PU you can plug a normal cable into the instrument, open volume and tone completely, select via the switch only this pu and measure the resistance at the other end of the cable.
- Done in a few minutes without (de)soldering.
