teaser360 Posted July 11, 2009 Posted July 11, 2009 (edited) just got myself a rockinbetter, the wiring is a bit of a mess, the tone variations are crap, going to re-wire using cts 250k and 500k pots and a new 3 way switch as that is a bit dicky aswell. Might change the pickups at a later date, not sure which ones to go for but was probabally thing about emg or seymour duncan soap bars. Also got myself a hipshot bridge on the way from the states.

teaser360 Posted July 15, 2009 Author Posted July 15, 2009 Just a quick update on how the faker is coming along, pots arrived today and started wiring them up, just waiting for the genuine rickenbacker 3 way switch to arrive, then i can get her back on the road. Quote
mrcrow Posted July 16, 2009 Posted July 16, 2009 why not stick to the original 250k pots? best of luck with a sensibly wired up two pup machine Quote

teaser360 Posted July 16, 2009 Author Posted July 16, 2009 just following the diagram from joeys bass notes, and other rickenbacker diagrams, tone pots are 500k and volume pots are 250k, although ive rewired it the rickenbacker way, i still dont have much tone adjustment, so im pressuming the stock rockinbetter pups are s*** Quote

I dont want to upset people in the process, i would rather share my experience, if i had put this on a rick forum there would be millions of bricks coming through my computer monitor thanks for all advice in advance tony Quote
Al Heeley Posted July 18, 2009 Posted July 18, 2009 (edited) I don't understand. Why would 500k pots give 3db more gain than 250's? At max gain the pots are zero resistance, ie: full volume. Now zero resistance on a 250k pot ought to be same as zero resistance on a 500k pot, or am I missinig something? On the rick replicas I've put together I've gone for the normal pickup rule of thumb: single coil will get a 250k pot and numbucker will get a 500k to help balance the pickup tone better. If you wanted to go for a 330k sweep you could always use a 500k pot and solder a couple of resistors (approx 485k each) onto the tabs as per this useful ready reckoner: [url="http://www.diystompboxes.com/analogalchemy/emh/emh.html"]http://www.diystompboxes.com/analogalchemy/emh/emh.html[/url] Edited July 18, 2009 by Al Heeley Quote

I shouldnt have used the word 'gain' because that implies its active, more accurate to say 250k pots are -3dB down in output due to increased loading effects. Think about how a pot works. When its turned all the way down youre shunting the pickup output to ground. When its on full youre connecting the pickup hot directly to the output BUT that hot still has the full value of the pots resistance between the pickup output and ground. So the lower the resistance the more signal will bleed to earth. Edited July 18, 2009 by Spartacus Quote

teaser360 Posted July 18, 2009 Author Posted July 18, 2009 Well shes up and running and im happy playing around with it and i just hope the rest of the band like it. Ive just fitted my homemade pickguardian, total cost £3.80 and a bit of time Quote
