I would just like to thank Sergio for his time and his help. I am a new user of this forum and have been having a number email conversations with him of a technical nature amongst other things. It would appear that Sergio has helped many people on this forum as well as myself. He is a thoroughly decent and generous guy. How many are there like him? Not many! So cheers Sergio and heres hoping we have loads of forum action in the future.

Many thanks to you, Sergio.

HE'S DA GURU!!!

I can't play without his tone monsters.
He gave me history lessons on RIC pickups with detailed structural drawings 2 years ago and I was enlightened since.

Thank you Sérgio!

So Sergio is the guy to talk to if you are doing a PU replacement on a Ric? What about wiring changes?

rickcrazy · Post by **rickcrazy** » Mon Jan 17, 2005 4:11 am

Not my department. Sorry. But some Forum members have come up with ingenious wiring changes, as you call them, namely Bob Young.

if you guys want to try something on a 4003 to make it hotter and have more treble ... then try putting 500k volume pots in your bass ... I am thinking of trying this on a 4003s5 someday ...

lars · Post by **lars** » Mon Jan 17, 2005 5:01 am

Technically, how is that working? If the volume is fully open, isn't it shorted having no effect on the cirquit?

grayk · Post by **grayk** » Mon Jan 17, 2005 5:08 am

So would it be .0047 cap and both pots changing to 500K to get a bit more treble or would you only do one or the other? Also I have phoned my local music store about the cap and he just called it a 047 cap. Am I safe with this ? When I looked on an electronics retailers website that has a store locally, it only listed 0.047 (and not .0047)capacitors. It is confusing for a non tech head ! It would seem like a commonly used cap for other makes, am I correct in saying this ? Please anyone out there speak in "idiot" just for me ??

Here's some info I got off the internet ...

Control pots are typically wired to control the volume or tone of your instrument. In some other case they are used to blend to sources or signals together, or can be wired to control onboard effects.

250K vs. 500K
Generally, 500K-ohm pots are used with humbuckers and 250Ks are used with single-coil pickups. 25K pots are used for active systems.

You can use any value you like, but a 250K will give a slightly warmer tone than a 500K pot. The 250K pot bleeds off (attenuates) some of the high frequencies to ground. A 1Meg-ohm pot will attenuate even less than a 500K pot, so if you want to hear your guitar "wide open" you may want to try one.
