If that doesn't work, try a 1meg. Hamster[/quote] But not more than the "bypass" pot I have now, presumably? Quote Link to comment Share on other sites More sharing options...
Hamster Posted January 30, 2008 Share Posted January 30, 2008 The 1 meg pot might get near it, but the tone pot mods make the most difference Hamster Quote Link to comment Share on other sites More sharing options...
Guest Posted January 30, 2008 Share Posted January 30, 2008 [quote name='OldGit' post='129417' date='Jan 28 2008, 05:04 PM']With the rotary control with the various capacitors, I'd need a rotary tone pot too yeah? Did it make a serious difference to the sound with each cap or was it subtle?[/quote] The varitone can be wired with a tone control as well but i just wired it with a volume, very simple hookup and incredibly useful, mine was used with a single darkstar ( big single coil) and with a simple click of a knob i could go from a deep dubby sound to Motown to almost Ricky like bite. Admittedly the Darkstar played a part but it was a very useful set up one which i may well recreate with a cheapo SX or similar, personally i don't see the point of adding a tone pot, i got a simple setup which worked much better than any other passive basses i had owned and had all the variation i needed Quote Link to comment Share on other sites More sharing options...

tauzero Posted January 31, 2008 Share Posted January 31, 2008 [quote name='Hamster' post='130888' date='Jan 30 2008, 07:05 PM'][quote name='OldGit' post='130870' date='Jan 30 2008, 06:41 PM'] Would a 500k pot brighten my darker sounding P pickup?[/quote] Yes - it will allow more highs through. If that doesn't work, try a 1meg. [/quote] Um, why would it allow more highs through? A pot is a simple resistance, which doesn't vary with frequency. Quick summary of resistances/impedances: Resistor (fixed or variable): a resistance which doesn't vary with frequency Capacitor: impedance which is inversely proportional to frequency - blocks DC completely, then the impedance falls as the frequency rises Inductor (coil): impedance which is directly proportional to frequency - so it increases as the frequency rises The effect of changing the volume pot is that (IIRC) it forms a potential divider with the pickup, so as the frequency rises, the proportion of the signal voltage across the volume pot would decrease. However, I don't know what the impedance of the pickup is - I would have thought it would have a pretty negligible effect, otherwise there just wouldn't be any top end. Oh hang on, it's a Precision, isn't it? Quote Link to comment Share on other sites More sharing options...

[/quote] Cheeky Well I'm a bit lost by that .. new strings arrived today so I'll try that first then .. .. should try the 500 k vol pot to see if things brighten up a bit? Then it's a pup swap to see if that makes a difference .. I have a Fender P pup lying around .. It's a bit old though and I understand they loose power as they get old ... or is that an old wives tale? Quote Link to comment Share on other sites More sharing options...
OldGit Posted February 6, 2008 Author Share Posted February 6, 2008 Swapped the Pup for my old P pickup and now it sounds like a Precision should. So now to sort my dodgy soldering and get the tone side of things back to normal ...) Quote Link to comment Share on other sites More sharing options...
