Pots, knob and cap help for SB 2 staked knob project

Postby jfh4242 » Thu Jun 27, 2019 2:50 pm

Hello ladies and gents.

I just bought a SB 2 Tribute. I want to install a tone knob. I will be trying to copy the same thing that Craig has done on his SB 2s. I've own a few of his and am very happy with the result.

I have never done anything like this before, I'm a total newbie. I am including the diagram that I am going to be using. Can any one point me to exactly which pots, knobs and cap that I need to purchase? If we can't do that because of forum rules, could you please describe as best you can what these things need to be? Since I don't know what I'm buying, it makes it difficult to buy the right thing.

Basically, it will be a staked knob on the P pickup. The staked knob will include a general volume knob and a J bass volume, the other knob will become a tone knob.

I will purchase a soldering gun and some wire. I guess that covers everything.

Thanks!

John

Shopping list:


Clean up and re-purpose one of your existing volume pots as a tone pot.

Good luck!

Thanks a million, Ken. Much appreciated.

So for the j knob that is currently on the Tribute SB-2...I can keep that knob and use it as a tone knob when I am done, right? I don't need to buy another knob. Is that what you mean by "clean up and repurpose one of your existing volume pots as a tone pot"? Sorry for the dumb question, I just want to be super sure.

Thanks!

Let's clear up what appears to be a misunderstanding.

These are knobs:

You will probably be able to use one of your existing knobs on the tone pot of your project. Or you can buy all new; just buy whatever you need for the potentiometer(s) (pots) you'll be using.

This is a potentiometer, or pot as they are commonly referred to.

This is not a knob. However, a knob is typically attached to the shaft of the pot to give the user something easy to rotate and to dress things up a bit.

You can use one of your current volume (not "J") knobs on your future tone pot if you want. Or replace it; it's up to you.

Is that what you mean by "clean up and repurpose one of your existing volume pots as a tone pot"?


What I mean by "clean up and repurpose one of your existing volume pots as a tone pot" is to desolder its current leads (wires), remove it from the bass, and clean up (remove) excess solder from the lugs to prepare it for reuse (repurpose) as your tone pot. It's the same value as a typical tone pot, so if it's in good shape you can reuse it. If you'd prefer to work with a new pot, purchase a 250KA pot from AllParts.

Thanks for clearing all that up for me, Ken. Your explanations were clear, I just never did this before so I couldn't figure it out.

I imagine this would work, in terms of a cap, right?

It would work, but 600 volts is WAY bigger than you need. Consider that the voltage seen by the cap is less than 10 volts.

Use this one: https://www.amazon.com/NTE-Electronics- ... B007Z7JF8O

It's essentially what G&L uses in their instruments.

Hiya Ken. I'd like to use what you pointed out, but it doesn't ship to Canada.

I've been trying to locate the part in Canada...not easy.

I may have to wait until I know someone who is going to the States. He could bring all this back to me.

Then you look in Canada.

Big companies like Amazon have sites in various countries, Canada is just one example. They may not stock everything that Amazon does in the US, and vice versa, and the pricing could be wildly different, but a little bit of looking goes a long way.
