Is this kit of good quality?

CTS pots, Orange Drop cap, Switchcraft jack, looks to be of as good a quality as any. If all you wanna do is fix up one bass, go for it.

I prefer to buy in bulk on eBay for those parts, and it ends up being cheaper than that, but there's nothing wrong with that kit.

I got 6 CTS 250K pots for $6, two caps for ~$2, and 4 jacks for ~$2. Search eBay before you buy, you may find a better deal accidentally.

 

CTS, Switchcraft, Orange Drop, cloth wire... This is top quality stuff.
I say go for it.

 

Here's the same thing cheaper.

It'll do the job just fine, yeah.

 

I've done business with GPR before. I would definitely buy from them again. I can personally vouch for CTS pots and Sprague Orange Drop caps. They were a definite improvement over the stock stuff in my P and my J.

I've got the same kit in a couple of my basses.

 

Wire it as a standard jazz bass and there will be no problems...

 

The Acme orange drops caps don't say "Sprague" on them so they probably aren't the real deal although they might sound the same
