Low End Bee Posted November 5, 2009 Share Posted November 5, 2009 (edited) I've just had a Wizard Thumper put in my 2007 MIA Precision. I got the shop to ditch the S1 and put in a new CTS vol pot. When I took it to rehearsal I noticed the volume knob on the bass is silent below 6-7/10. At max volume the red clip light on the amp didn't come on until the input was at about 3 o'clock where the original Fender pickup was doing this at just after 12 o'clock. My DiMarzio equipped Precision clips at about 10-11 o'clock. I was expecting this to have a similar sort of output. That said it sounds lovely. With more of a thicker warm P Bass tone than before. Have the well known guitar shop in Kew done something wrong. Is it a faulty pot/wiring. Or is it the pickup? I'm rubbish with electrickery me.

wateroftyne Posted November 5, 2009 Share Posted November 5, 2009 Hmm.. I'm not technical enough to suggest anything other to say that the Thumper in my P had a stupid amount of output compared to a standard P... Hope you get it sorted soon.

Hamster Posted November 5, 2009 Share Posted November 5, 2009 If you're happy to pop the pickguard off, what numbers are written on the pot they've put in? - also perhaps take a photo to put in your post? Quote Link to comment Share on other sites More sharing options...
7string Posted November 5, 2009 Share Posted November 5, 2009 Do you know what type of pot it is as there's linear and audio taper. An Audio works gradually as you turn the knob, a linear pot has all the action happening nearer to full. Have a look at your receipt or have a look for an 'A' or a 'B' on the pot itself.

Low End Bee Posted November 5, 2009 Author Share Posted November 5, 2009 I've whipped the pickguard off. They've put a 500k pot in place of the 250k Fender S1 original. The only lettering I can read is '0924 CTS' the rest is obscured by a bird poo of solder. The receipt just says "CTS pot" Quote Link to comment Share on other sites More sharing options...
Deep Thought Posted November 5, 2009 Share Posted November 5, 2009 I did a very similar thing with my '07 S-1, except I had a SD Quarter Pounder put in. My MIM P has a Thumper in it, and I have to say the SD was always noticeably louder. The Thumper isn't quiet enough to be a problem, it just needs the amp turned up a bit higher than the SD did, but it was certainly not as loud as I was expecting.

BOD2 Posted November 5, 2009 Share Posted November 5, 2009 Any chance of a photo or two of the wiring ? That might help check to see if it all looks right. Quote Link to comment Share on other sites More sharing options...

Low End Bee Posted November 13, 2009 Author Share Posted November 13, 2009 In the end I took it back to Chandlers. The 500k algothingy pot was swapped for a 250k linear and the measured 13.2K thumper is pumping out as it should now. They were actually very good about it and did it on the spot. Happy now Quote Link to comment Share on other sites More sharing options...
