I bought the Helms 33" scale 5 string on TB a few weeks ago, which was wired like a standard jazz bass. I hate dual volume controls, so I rewired it with the pickups in series, one volume, one tone, one knob that did nothing. However, the output jack was on its way out and yesterday was out- not a fun gig trying to not move the cable during a 4 hour wedding! So when I got home from my gig (nothing like soldering at 2:30am when you have a 7:30am church call....), I pulled out the disconnected pot and put a jack in that hole because I did not have a barrel jack here, just the kind that would go on a P-Bass pickguard. So it works fine, but the tone pot is kind of crackly anyway, so I think all new internals are on tap. So, I have read a million different things on here, just want to clarify based on my situation. I favor a motown-ish bass sound, I don't dig the modern roundwound type tone- the bass is strung with flats and I use a sansamp RBI into a gk400rb and a gk 115 cab. So, what I would like to do, I think, is volume, series/ parallel switch, and tone knob, with a .047 cap. Maybe I should go a little darker on the cap. However, I don't play with the knobs on my bass too much while playing. I was then thinking maybe instead of a tone knob getting a dpdt on/on/on switch and putting a bypass and 2 other caps, kind of a varitone-ish idea though not really a varitone. So quick summary- volume, series parallel switch, tone or volume, series parallel, tone switch with no cap and 2 other values or kill switch, series parallel switch, tone switch. I may want a volume swell sometimes, so I think a volume knob would be good. Now, after all that- the real question. I went on basspartsresource, and selected Item Options Quantity Remove Amount BLACK MINI SWITCH ON ON Item # EP 0081-003 $9.79 CTS 250K AUDIO SPLIT SHAFT POT Item # EP-0085-000 $9.38 SWITCHCRAFT MONO 1/4 in. PANEL JACK Item # EP 0151-000 $7.99 SPRAGUE .047 ORANGE DROP CAP Item # CAP-OD47 $1.99 I don't know what cap is in there now, but it looks like a green chiclet. I have heard the orange drops are good, and I can deal with $2, so that's not an issue. If I do a tone knob, do I want 250k audio taper? I want a darker sound- the bass is mid heavy so if 250k keeps it darker that's cool, but do I want audio taper or linear for the tone? I think audio from the reading I did, but there's just as many opinions either way. Or maybe I should go for the "no load" tone pot. Sorry for the long post, I don't know any other way!
