Compensated HSS auto-split: advanced Strat diagram
If you are looking for a hss auto split wiring Clear and practical, you're in the right place. Here you'll find the diagram, explanations of the connections, and tips for avoiding common mistakes.
Introduction
This advanced diagram combines a bridge humbucker with two single-coils (middle and neck).43 It resolves impedance imbalance by introducing compensation resistors (single-coils work at while the humbucker uses optimal ) 17 and performs an automatic split of the bridge humbucker in position 2 to preserve the classic Stratocaster tone without hum.17
Wiring diagram
Download the SVG diagram and use it as a reference while soldering. The star ground is the central point: all ground wires must converge there.
How to read the diagram
The setup includes a bridge humbucker (4 conductors), two passive single-coils (with RWRP middle), a logarithmic master volume potentiometer of , two no-load tone potentiometers of , two compensation resistors of , a capacitor of , and a 5-way 4-pole selector (Super Switch).17
Practical steps
- Prepare the components and check the values of potentiometers and capacitors.
- I soldered the hot wires following the diagram, avoiding unnecessary jumpers.
- Connect all the masses to the indicated star point.
- Check the continuity between the bridge, jack and potentiometer covers with a multimeter.
- Test the instrument and fix any buzzing.
Tips to avoid buzzing
Avoid the ground loopIf the potentiometers are on a common metal shield, do not solder ground wires between their caps. Use an open "C" or "horseshoe" path and connect each ground to the star center. For more information on modifications, see also guitar modification guide.
FAQ
Which potentiometers should I use?
It depends on the pickup: single-coil generally 250k, humbucker 500k, active 25k.
Can I use a different capacitor?
Yes, but the value changes the cutoff frequency of the tone. Higher = darker sound.
