I think you need to sort out your wiring harness first.
That said, some pickups I've had that worked great in a 335: WCR Crossroads, Darkbursts, Seth Lovers, 57 Classics. The wood makes a big difference though.
This is why having a GOOD tech / luth look at it is a good idea.Look at the cheap stuff before changing pickups...
Pots tend to drift overtime. I've seen old gibsons with pots that have drifted down to 50k - which is as dark/muddy as can be.
Likewise, caps dry out and often drift towards rolling off more highs. Under such conditions, NO pickups can sound particularly good.
Sometimes the fix for a dull sounding guitar is much simpler/less expensive than a pickup change.
Thanks, I will try that, I will have to create an account I think. I thought I could just upload them directly to my post, guess not. Hopefully will have this in a few, I really want to know what I have here.Upload the pictures to Flickr or Photobucket or any online picture-hosting site, really, then when you want to post them here, click on the little box with the mountains in it, and insert the URL to the picture. If you're using Flickr, there's a "share" option above each of your photos, and you can just click that, choose the size of the picture you want, and then copy/paste the code for bulletin boards into your post here on TGP.
Hope that's helpful.
Thanks very much for the great information! I will research BCS as well. Curious to know why such the big price difference.Here is a wiring kit at half RS prices.
I have used these and they are good.
