fixing that bass/pickup click in the mix?

[JWL]

The best solution is to fix the bass, which I would regard as "broken." LOL

If he refuses to fix his bass, and if I wasn't being paid to spend the time to edit out the clicks (very time consuming), I'd throw an EQ on there to filter out the clicky bands, and then post-EQ compress the signal a bit.

My fix-all for this is to just have them play closer to the bridge. Have them play right on it if they suck that bad. It WILL effect the tone a bit, but it will also let you get a useable track which you can tweak later.

I recently used the UA Precision Multiband Compressor for fixing just such a thing. I had some pretty weird overtones and string buzz against the neck that I pulled out/down with the MBC. I found the bulk of the frequencies to be around 5 kHz and if you solo that portion in the MBC and vary the settings abit, you can fairly quickly find out what you need to pull down.
