Gunstreet Les Paul Junior Wiring Harness - Classic



Our kits are a perfect drop-in replacement for your Les Paul Junior style guitar, whether you want to change how your instrument sounds, or just want to improve the durability we have something perfect for you!

  1. Red 50’s Wiring (Vintage High Pass Filter) This wiring was found in the first gen of electric guitars. It features a transparent sound as you roll off the volume at the cost of a steep volume taper and an on/off tone control that interacts a lot with your volume position
  2. Blue Modern Wiring: (Low pass Filter) This comes standard in most instruments and is what most people are familiar with when it comes to functionality. This style is what you call a low pass filter, meaning as you roll the volume down more highs will disappear.
  3. Green Volume Bleed (Modern High pass Filter) Often called a “treble bleed”, this circuit changes the modern wiring into a high pass filter. Get this kit if you like to use both your volume and tone control a lot and want more highs at lower volumes.
