Recently purchased a new Nordstrand MM 5.3 pickup for a Stingray 5. I am trying to retrofit it in with a Glockenklang preamp. As such, I needed a 3-way switch to use for the series/parallel/single coil splitting before going to the preamp. I think I may have wired something incorrectly, as one position has normal volume but the other two positions are extremely quiet unless I boost the EQ all the way. I am also experiencing ground noise when my bass is aimed at lights. Then I can barely hear an extremely quiet signal. I used the wiring for the
3-way switch (used a fender 3-way switch with a 3.3k 5% tolerance resistor) from the Seymour Duncan website, and connected it to
the preamp (pdf warning) as follows:
- Desoldered the blend pot from the preamp, soldered the "wire to preamp" from duncan diagram to the fourth from the right solder spot on the volume pot of the glockenklang.
- The ground wire from the duncan diagram is soldered to the ground spot on the glockenklang.
- battery, ground, and output wires from preamp wired as shown.
- ground wire from bass wired to output jack.
My only thoughts are that:
- I wired the 3-way switch wrong
- I should have I soldered the ground from the 3-way switch to the output jack, or the solder spot next to where I soldered the signal coming from the 3-way switch (third from the right on the glockenklang volume pot)
- I need to solder the bass ground wire to the ground spot on the glockenklang preamp
I'd love some assistance on this as I am at a total loss as to what to do right now other than trial and error, which runs the rick of me accidentally burning something out with the soldering iron going over the same spots so many times.
