Hi there

It seems.... Success!

Changing the 25k pot for a 250k pot, and I've got an useful tone.

It's not a wonderful range of tone, but, tone at all...

The capacitor is welded to the midle connection of the pot

Kind regards

Hi there

Sounds useful for me.

I'll try this weekend to replace the 25K pots with CTS's 250K pots, keeping in place the 0.1uF capacitor

Thanks for your info 

Kind regards

'unearth'?

Sounds really bad......

Sorry for your lost...

Hi there.

As I read before:  "active but with a passive tone control". Maybe is a good idea to check a pasive 250k pot as tone, with 0.1 uF capacitor, instead de 25K pot installed now?

Thanks

Hi there

It is a linear pot 25k.

Do you think another value should work as tone pot, like a CTS 250k pot?

Kind regards

Thanks for your info.

I've got some news!

The tone pot seems work, but not all amps can detect!

So, Maybe the orange drop capacitor 0.1 uF appears to be wrong choice?

Another capacitor value could be better?

Thanks in advance

Kind regards

Hi there. There goes the pics. I've made some mods, with no results. Vol and tone pots are Alpha 25K, now, with a capacitor 0.1 uF. The wires now are: from blend pot to vol pot. From vol pot to tone pot. From tone pot to jack. The tone pot still doesn't work. Blend and vol works properly. There is a kill switch to save battery when the cable is plugged, very useful during the discussions in the rehersals session.

Kind regards

Hi there
I've got an used RSB bass and I love it, serial 06513923, 2 active pickups, 1 vol, 1 bal, 1 tone, but the tone pot doesn't work. I supose the previous owner modified the factory wiring, and I can't find an appropiate diagram in order to restore the original wiring.
So, what can I do to find a correct wiring diagram? Actually, I use the amp tone pots or the pedal board to get the appropiate tone for each moment, but I really need to set the bass to factory wiring.
Any idea to help me?
Thanks a lot from Spain.
