SLPK-1G for Gibsons

Put some teeth into your guitar! More body, more volume and a clear tone that can cut through a mix; that is what to expect with the BCS Standard series. This kit is a complete electrical replacement for any Gibson Les Paul or LP copy with a thick arch top that uses long shaft pots. To know if your guitar needs the long shaft pots you will need to remove one of your original pots and measure the bushing (the threaded part of the shaft). If the bushing is 3/4″ (19.05mm) long then your guitar takes the long shafts, if it is 3/8″ (9.53mm) long you will need the short shafts so see our SLPK-1 kit.

We use only high grade components in our kits to bring out optimum performance.

Bourns Potentiometers: The SLPK-1G uses 500K Bourns Pro Audio Guitar, Long-split shaft pots with an Audio taper and a low torque (which means these pots turn VERY easily). We chose the Bourns pots because we found them to have a superior taper over the CTS pots we used to use. These pots have an 18 spline shaft so your U.S. spec knobs will not fit without first pinching the top of the split shaft together and then slowly push them on. Import knobs will fit fine. If your guitar is an actual Gibson then your new pots should fit in the pot holes of your guitar just fine, but if it is a copy or another brand guitar that is using a long shaft pot your volume and tone pot holes may not be not 3/8″ in diameter, if so you will need to open them up for the new pots to fit. Don’t worry this is easier than it sounds and a step by step is included in the instructions.

Capacitors: We have selected the Mallory “Mustard” cap .022uf 400v capacitor for a pristine clean tone with no “warming” tone coloration. We used to use the MOJO Dijon capacitors, which were built to sound like the Mallory caps, but we decided instead of using a capacitor that was built to emulate the Mallory “Mustard” cap, we would just go ahead and use the real thing. Mallory is now owned by Cornell Dubilier so if you see that printed on the side instead of Mallory, don’t be alarmed, they are still made the same way and sound fantastic.

Switch & Jack: We use Switchcraft switches and jacks to provide reliable switching and rock solid connections for years to come. The SLPK-1G comes with a long shaft 3-way toggle switch and a cream tip (black or amber can be substituted on request) and a deep thread nut.

Wire: We use high quality cloth covered wire for the standard series to guarantee optimum electrical transfer with a lower resistance so your tone will not be hampered in the least. We use 22 gauge solid core wire for the conductors and 18 gauge thick stranded wire for the ground. We know that everyone else uses 24 to 26 gauge thin stranded wire and that theoretically it gives you more electrical transfer because of the higher number of strands, but we have found that the higher gauge solid core wire and thick stranded wire (therefore fewer strands) lowers the resistance and changes the inductance which results in a more detailed tone. The electrical differences are very small but they are cumulative with the enhancements provided by the other components which results in a superior tone.

This kit is wired to a modern Gibson Les Paul wiring schematic.

Build It Yourself: The unassembled version of this kit comes with everything the assembled kit does including heat shrink, volume mods (tone bleed mods), solid tinned ground wire and an Assembly Template. We also include extra wire just in case you make a mistake and need a little extra.

Standard LP Complete Installation Instructions

Standard LP Wiring Schematic

  • Switch to Neck Volume:              11 5/8” or 295.27mm
  • Neck Volume to Neck Tone:         2 1/2” or 63.5mm
  • Neck Volume to Bridge Volume:   2 1/8” or 53.97mm
  • Bridge Volume to Bridge Tone:    2 1/2” or 63.5mm
  • Bridge Tone to Neck Tone:          2” or 50.8mm
  • Bridge Tone to Output Jack:        1 3/4” or 44.45mm
  • The wires of the switch harness have a total diameter of 1/4″ (6.35mm) and is designed to run through the channel that is routed in the body of the Gibson Les Paul that runs under the pickups directly from the switch to the control cavity. If your guitar does not have this channel cut into it and uses small holes drilled in the side walls of the pickup cavities for your switch wires to run through you will need a different wire harness. Please email us for details.

Turn Around Time

Due to the expansion of our customer base, our turnaround times are 3 to 5 weeks from the time you order. We have recently picked up two guitar manufacturers that we are building wiring harnesses for, and the word of mouth about the quality of our work and customer service has expanded our customer base tremendously. Each kit is built to order, and in the order it was received. It will take some time for you to receive your kit, but it will be well worth the wait, guaranteed! - Bill Brown/owner BCS Guitars.
