KVG Music Products


Musical expression, fundamentally, is limited not by the musician but by the limits of musical instruments. The range of notes, dynamic limitations, and mechanical restrictions of the instrument set the framework within which the musician must form their art.

KVG is dedicated to fostering and advancing musical expression through bespoke musical instruments, effects and amplifiers. We're pushing the technology to widen the musical palette available to the artist.
“Unless you say otherwise…” (The standard configurations for our custom guitars.)
Unless requested, we use the standard 25.5" scale length for guitars, and 34" scale length for bass guitars.

We handcraft all our pickups for unexcelled tone. The sound of our pickups is unique and distinctive. We do not directly copy the tone of other pickups, although some of our pickups may be evocative of existing and vintage tones.

Standard necks have 22-frets, and we also offer 21 and 24 fret neck options. All necks receive our Sandburg SilkGlide neck treatment for fast, easy playability.

Bodies are crafted from swamp ash, alder or mahogany standard, but we will be happy to use any other wood you desire. Neck woods are usually maple with either rosewood or maple fingerboards, but we offer all suitable wood species.
Guitar Hotrodding Services (when out of the box is out of the question.)
Solid Body Electric Guitars and Basses only.

When we receive your guitar, we study its sound by playing it. Next, we use our proprietary Music Instrument Sound Analysis System (MISAS) to measure its sustain for each note, perform a spectrographic mapping analysis and a harmonic content analysis. Based on the results of these tests, we then recommend the modifications required to give your guitar more tone, more character, increased clarity, fullness, sustain, sensitivity and volume. Afterward, your guitar will be much more responsive and far more versatile while creating a unique sound that only you will have.

During your guitar's modification, we examine it for wear and damage, then undertake the necessary work to repair any wear or damage, and to make string bending easier and eliminate dead notes, including:
  • Fret Milling or Replacement (if badly worn).
  • Fret Leveling.
  • Fret Recrowning.
  • Fret Polishing.

Quality Assurance (a motivational speech.)
Music is the ultimate expression of improvement and change, achieved through the skill of its practitioners, appreciated by its fans. New sounds, new styles, new twists of “what has been.” These result from the inspirations that foster musical expressions. That’s why we create both new sounding instruments and improvements on existing instruments.

New technologies can result in meaningful progress and genuine improvement. We don’t adopt new technology unless it does something demonstrably better. We don’t cling to the old out of stubborn nostalgia but rather from our knowledge of what works and what doesn’t.

Do you have an idea for a new feature or new guitar technology? Tell us, we’ll do everything we can to make it work.

Our instruments are tested before they come to you in our working recording studio. The studio provides an ideal environment to test, then perfect, instruments and equipment in the same situations and for the same purposes that studio crews will use the equipment. It allows us to involve working musicians and experienced audio professionals in the inception, creation, refinement and perfection of a new product and also provides a training environment for our customers. This hands-on real-world experience ensures that everything we make will meet your needs.

We’re confident our work will be right, so every guitar we make has a 5-year warranty against defects (that excludes only obvious abuse). Once you receive your guitar, you have 45 days to decide how cool it is, but if you want to return it, you may — but it has to be as good as new, in the original packing - otherwise we have to charge a 25% restocking fee to fix it and clean it up.
Shipping and Delivery Times (excluding space alien abductions, Bigfoot raids and global apocalypse.)
Delivery times depend on the availability of the parts we need for your design, the length of time it may take to find a rare part or to have a custom-made part delivered, and the complexity of the design itself. Because each instrument is made by hand to your individual requirements we cannot simply pull an item off the shelf and deliver it to you. We will advise you of delivery time when we discuss your order with you.

We will ship your order to you using only one of the following approved carriers in order to ensure the safe arrival of your order:
  • United States Postal Service (USPS).
  • United Parcel Service (UPS). UPS is our recommended and preferred carrier.
  • Federal Express (FedEx).

Please do not ask us to ship your order using any carrier other than our approved carriers. Shipments by a non-approved carrier would mean that you would have no insurance, no recourse of recovery if your order was lost or damaged in shipment, and no warranty coverage whatsoever.

Before we ship to you, you will need to verify that the recipient ("ship to") address is correct along with a working telephone number at that address. We recommend you include an email address as well.

Note that you will be asked to sign for all orders having a value greater than $200.00 USD; this is merely an additional layer of protection against loss for you.

Should you have other questions or concerns about these shipping policies, please contact us.
