VSGK-1

Assembled: $90.95

Unassembled: $66.95

Put some warmth and classic tone in your guitar! More body, fuller tone and letting the subtleties of your pickups come through; that is what to expect with the BCS Vintage. This kit is a complete electrical replacement for a Gibson or Epiphone SG, SG copy or any guitar with a standard SG layout.

50’s Wiring: This kit is wired to a 1950’s Gibson Les Paul wiring schematic. With the 50’s wiring the overall tone gets stronger and more transparent, meaning the notes seem to “open up” more. Another benefit is the loss of treble when rolling back the volume is reduced considerably and a volume mod, or treble bleed mod, would only improve this slightly.

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

Bourns Potentiometers: The VSGK-1 uses 500K Bourns Pro Audio, short-split shaft pots with a standard torque. We chose the Bourns pots because we found them to have a superior taper and a smoother feel than the CTS pots we used to use. These pots have a 24 spline shaft so your Epiphone or import knobs will not fit without first pinching the top of the split shaft together a little and then slowly push them on. U.S. spec knobs will fit fine. Click here for our selection of U.S. spec knobs. Be aware that if your volume and tone pot holes are not 3/8″ in diameter then 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.

Audio or Linear taper for your volume controls? You can choose between Audio taper or Linear taper for the volume pots but the tone pots are Audio taper only. What’s the difference and which one should you use? That depends on you. The Audio taper falls off rather quickly as you volume down with a clean tone (i.e. your tone will drop about 50% from 10 to 8.5 and then smooth out from there) but when using overdrive you can “clean up” your tone without losing volume. As you decrease the volume the amount of drive from your guitar decreases so your overdrive breaks up a lot less and you end up with a much cleaner tone and no real volume loss until you get down to about 3. The Linear taper acts more like you would expect from a volume control giving you a much more even taper as you volume down with a clean tone. When using distortion or overdrive with a Linear taper there is no real discernible volume drop as you turn it down until you hit about 3 and the amount of drive pushing the distortion does not change very much which results with a small amount of change to your distortion. If you like to use your volume pots to clean up your distortion then the Audio taper is for you, but if you want smooth volume control with your clean tone and run your distortion full open, or don’t use distortion at all, then go for the Linear taper.

Capacitors: Oil filled capacitors have a much smoother, more natural sound than the standard ceramic capacitors. While they sound better, they usually cost a lot more as well, but a higher price does not guarantee a better capacitor. Currently we are using the NOS Russian K40N .022uf/400v paper in oil capacitors. These capacitors (not shown in the photos, we need to take new pictures) use an aluminum foil conductor with an oil saturated paper for the dielectric that is sealed in glass and encased in a metal body that is painted with a red non conductive paint. We have used these capacitors in the past when our supplier was not able to deliver the caps we were currently using, so we know how these caps sound and perform. We decided to start using these capacitors as our first choice caps because not only do they sound great, but they are built like a tank and don’t fail. These caps are also reasonably priced so we can provide fantastic tone to our customers while keeping the price from going through the roof.

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

Wire: For this kit we use high quality cloth covered wire 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. Normally we use the vintage accurate shielded wire for the vintage series but due to fact that Epiphone does not always cut and drill their control cavities the same there were problems installing this kit with the shielded wire due to the way it was attached on the sides of the pot. That is why we switched to the cloth covered wire for this kit.

This kit is wired to a 1960’s Gibson SG 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.

*NOTE: Each kit is assembled in our shop at the time of purchase so we can accommodate any changes needed for your guitar. If your guitar is not a Gibson or Epiphone SG and has a slightly different layout (maybe the volume and tone pots are a little further apart) your kit may require a custom layout to fit. The custom layout costs an additional $12.00 and we will need you to send us the measurements for your guitar. Click here for measurement and photo requirements for a custom built kit. Please measure all of the components from center to center. Here are the measurements that our kits fit;
