SonicSid Posted February 20, 2007 Report Share Posted February 20, 2007 A member of another board (TalkBass.com) asked for a modified J-bass diagram, I decided to see what I could come up with. He wanted: 3 switches - Neck on/off, Bridge on/off, Series/parallel. 1 volume, no cap. Will this work? It seems I may have some weird phase reversal type thing going on. An experts opinion would be greatly appreciated. Thanks, Sid Quote Link to comment Share on other sites More sharing options...

unklmickey Posted February 20, 2007 Report Share Posted February 20, 2007 Is this gonna work? In a word.... No... okay SonicSid, you got the one word answer, here's the long version... at the heart of your circuit, is a series/parallel switch. when turning off a pickup in a parallel circuit, you just disconnect it. when turning off a pickup in a series circuit, you disconnect it AND replace it with a "shunt". your circuit will work correctly in series, whether both, one, or no pickup is selected. but in parallel, it will only work with both pickups on. IMHO, this leaves too many possibilities for "dead spots". there are a few alternatives. you could use 2 DPDT switches, and get the following combinations: both parallel neck only bridge only both series. i do like this one. it requires 2 fairly simple switches, and there are no dead spots. you could use a SP3T switch and a DPDT to get the above combination, but in a different manner. in one position of the DPDT, the SP3T functions like a LP or Tele selector. neck / both (parallel) / bridge in the other position of the DPDT, the pickups are in series regardless of the position of the SP3T. although, it required 1 more complicated switch, having the series combo available at the flip of one switch is seen by some as a huge benefit.

SonicSid Posted February 21, 2007 Author Report Share Posted February 21, 2007 Thanks for the reply unklmickey, and especially the alternatives. I'll draw one up as you described in the first example, if only for the sake of simplicity. It does, after all, do what the guy wanted it to do.

unklmickey Posted February 21, 2007 Report Share Posted February 21, 2007 hi Sid, these switch puzzles are fun. i dont want to take any of that away from you so .... no peeking. when you solve it, compare your result to this: http://guitarnuts2.proboards45.com/index.c...ge=1#1158330256 and/or this: http://guitarnuts2.proboards45.com/index.c...ge=1#1130287410 it will be interesting to see the similarities and differences between what you come up with, and what i did. good luck, unk Quote Link to comment Share on other sites More sharing options...
SonicSid Posted February 23, 2007 Author Report Share Posted February 23, 2007 Very cool! I can't imagine a better way to learn. Thanks Unk! Sid Quote Link to comment Share on other sites More sharing options...
