    In General<\/strong><\/h3>\n

    When using a 5-way superswitch with 3 single-coil pickups, using the patent-pending approach in the previous tutorial, \u201cAn All-Humbucking 5-Way Superswitch Circuit in an Electronic Guitar with 3 Single-Coil Pickups<\/a>\u201d, only the two pickups with the same poles up can form a contra-phase pair.\u00a0 And to do that (in this approach \u2013 a Prov. Patent Application has been filed on a more general approach<\/a>), one of those two pickups has to use two of the switch poles, so that it can be reversed against the other pickup of the same magnetic pole up.\u00a0 Don\u2019t confuse switch poles with magnetic poles, they are two different things.<\/p>\n

    Notice the different diagram symbols used in this tutorial.\u00a0 Using both N for neck and for a north pole can be confusing.\u00a0 So the poles in switching diagrams here are shown as black and white.\u00a0 It doesn\u2019t matter whether a white pole up is north or south, only that the black pole up is the opposite.\u00a0 Note that here N, M and B stand only for the neck, middle and bridge pickups.\u00a0 See that those pickups have the output marked with + and -, to show the polarity of the electric signal for the same motion of the string over the pickups, and which end of the pickup is connected to which pole terminal on the 5-way superswitch.\u00a0 The wires shown crossing are not connected unless a dot appears at the crossing.\u00a0 Note that the switching diagram goes from the bridge to the neck from left to right.<\/p>\n

    In the soldering diagrams, the wipers (switch poles) have been moved to the other ends of the switch throw terminals, so that the direction toward the bridge is the same in both diagrams, left to right.\u00a0 The switch throw terminals correspond physically to superswitch terminals shown on the bottom of the switch in the images in the previous tutorial (An All-Humbucking 5-Way Superswitch Circuit in an Electronic Guitar with 3 Single-Coil Pickups<\/a>).<\/p>\n

    Note the rearrangement of the switch pole terminals.\u00a0 The top (outside wafer) switch pole terminals go only to + pickup signals.\u00a0 The bottom (inside wafer) pole terminals go only to \u2013 pickups signals.\u00a0 The remaining + pickup signal goes to the output and the remaining \u2013 pickups signal goes to ground.\u00a0 This tends to simplify the switch soldering diagram, with a minimum number of wires crossing from top to bottom.<\/p>\n

    Note that the switch wiring and soldering diagrams must have the same number of terminals soldered, including the same numbers of terminals soldered to the output, and the same number of terminals soldered to the ground.\u00a0 Use this for a double-check on your work.\u00a0 And then triple-check everything, including what I\u2019ve written.<\/p>\n

    Pay attention to the theory.\u00a0 These diagrams are easy to confuse.\u00a0 If you are unable to follow it and use it to double-check your work and mine, you will have little clue how to fix it if something goes wrong.<\/p>\n

    Version A<\/strong><\/h3>\n

    As noted, either of the middle or bridge pickups, having the same pole up, can be used with two of the switch poles to form a contra-phase pair.\u00a0 This first version puts those two poles on the bridge pickup.\u00a0 Note that the switch poles connected to B+ and B- show the wipers starting at the left-hand side of the right set of 5 throw pairs, while the actual solder terminals are on the left side of the bottom of the switch, labeled N+ and N- in the previous tutorial (where the middle pickup had the odd pole up).<\/p>\n

    This is the 5-way superswitch switching diagram for the case of three single-coil pickups where the pickup with the odd pole up is at the neck, and the pickup using two switch poles is at the bridge.<\/p>\n

    \"3<\/a><\/p>\n

    This is the 5-way superswitch soldering diagram for the same case.<\/p>\n

    Version B<\/strong><\/h3>\n

    This is the 5-way superswitch switching diagram for the case of three single-coil pickups where the pickup with the odd pole up is at the neck, and the pickup using two switch poles is at the middle.<\/p>\n

    Final Notes<\/strong><\/h3>\n

    In this case, the middle and bridge contra-phase pair has been wired in series because of the expectation that a parallel connection, although brighter, will be much weaker and sound tinny.<\/p>\n

    Because of the possibly competing factors mentioned in the post on HB general principles<\/a>, one cannot say whether the HB pair (N+B) is brighter or warmer then the HB pair (N+M), without actually wiring it up and either listening the result or measuring it with a spectrum analyzer.\u00a0 I have not done so.\u00a0 Nor can one say which of the pairs (N||B) and (N||M) is warmer or brighter without testing.\u00a0 Note that the result of (N+M) will be the same tonally whether the odd pole is at the neck or middle.\u00a0 However, one can expect that with the odd pole at the neck, (M+(-B)) has the same tonal output as ((-M)+B), and that either may be brighter than ((-N)+B) or (N+(-B)) with the odd pole in the middle.\u00a0 Whether or not they are brighter than (N||(-B)) might be debatable without testing, but it seems likely.<\/p>\n

    In the case of the odd pole a the bridge, the contra-phase pair must be the middle and neck pickups.\u00a0 According to the general principles of HB pairs<\/a>, pairs closer to the neck will be warmer.\u00a0 Therefore, one can expect less tonal difference between the HB pairs of that case, due to conflicts of the general principles.\u00a0 But like all else, this is subject to testing and verification.<\/p>\n

    Nevertheless, the standard 5-way switch provides only 2 parallel HB connections, (N||M) and (M||B).\u00a0 Certainly, the (N+M), (M+B) and (N+B) connections will be warmer, merely for being serial.\u00a0 And also the contra-phase HB pairs of neck and bridge (middle odd) and middle and bridge (neck odd) will be brighter than a \u00a0single bridge pickup alone, merely for being contra-phase.<\/p>\n

    You have now been given enough tools to design, build, test and decide for yourself which is best and suits you.\u00a0 Whether or not you will demand any more from guitar companies is your decision.<\/p>\n","protected":false},"excerpt":{"rendered":"
