2025 K-Line Springfield – Rosewood Fretboard, Sonic Blue Relic

Jam Session Guitars is proud to be an authorized K-Line Guitars dealer!

K-Line Guitars is a USA-made brand based in St. Louis, Missouri, founded and built by Chris Kroenlein and his small team of skilled craftsmen. Chris has earned a reputation for building exceptional vintage-inspired instruments using hand-selected woods, premium hardware, and K-Line’s own hand-wound pickups.

K-Line guitars are outstanding players with the look, feel, and attention to detail you’d expect from a high-end Custom Shop instrument. Their builds can range from clean, new-old-stock-style finishes to beautifully executed relic work, with an emphasis on vintage-correct aesthetics and playability.

This preowned K-Line Springfield is a great example of what makes these guitars special. Finished in a beautifully aged Sonic Blue nitrocellulose lacquer, the lightweight alder body has just the right amount of factory-style relic work. The combination of the classic finish, rosewood fretboard, and aged appointments gives this Springfield a distinctly vintage-inspired look. It's overall in excellent condition with no visual blemishes outside of the beautiful factory aging. Electronics work as expected and sound great!

The maple neck features a comfortable .850" “C” profile and a 10" radius, while the rosewood fretboard provides a smooth, familiar playing feel. K-Line’s hand-wound Custom ’64 pickups deliver the kind of articulate, open vintage tone you want from a great Strat-style guitar, with plenty of sparkle, warmth, and definition.

This is an excellent opportunity to pick up a USA-built K-Line with a great combination of vintage styling, premium components, hand-wound pickups, and a very cool Sonic Blue relic finish.

Includes:

• K-Line padded soft case

• Certificate of Authenticity

• Tremolo arm

Charvel Super-Stock SD1 H FR – Diamond Life, Ebony Fingerboard

This Charvel Super-Stock SD1 H FR is in excellent condition, with no visual blemishes beyond the very cool factory relic treatment. The electronics work exactly as they should and sound great. This guitar is an absolute monster and a ton of fun to play. Includes the original padded case and tremolo bar.

The Super-Stock SD1 H FR is Charvel at its most stripped-down and aggressive. Built with a solid alder body and designed around the classic Southern California shredder formula, this guitar combines serious high-performance playability with unmistakable Sunset Strip attitude. The Diamond Life finish and factory-aged treatment give it the look of a guitar that's already spent years on the road, while the modern construction makes it incredibly easy to play.

The graphite-reinforced maple neck is built for speed and stability, with a comfortable hand-rubbed urethane finish and a 22-fret compound-radius ebony fingerboard. The 12" radius at the nut gradually flattens to 16" higher up the neck, giving you a comfortable feel for chords and rhythm playing in the lower positions while providing the flatter surface you want for fast leads and bends.

At the heart of the SD1 is a single Seymour Duncan JB Model humbucker at the bridge. It's a classic hot-rodded pickup with plenty of output, powerful lows, aggressive upper mids, and crisp highs. Paired with nothing more than a single Volume control, the setup is refreshingly simple: plug into a good amp, turn it up, and go.

The recessed Floyd Rose FRT O2000 double-locking tremolo completes the package. Whether you're after subtle vibrato or full-on dive bombs, the Floyd delivers the tuning stability and range you'd expect from a serious shred machine.

If you're looking for a high-performance guitar with serious attitude, this Super-Stock SD1 H FR delivers. One pickup, one Volume knob, a fast neck, Floyd Rose, and a killer relic finish — it's a focused, no-nonsense rock and metal machine that's incredibly hard to put down.

2024 Collings City Limits – Aged Jet Black Top with ThroBak P-90s

This 2024 Collings City Limits is in excellent condition with no visual blemishes outside of the light factory aging. Electronics work as expected and sound incredible. Collings is known for exceptional craftsmanship and attention to detail, and this guitar is a great example of that. The ThroBak P-90s are absolutely killer, delivering a huge, dynamic, and incredibly musical tone. Includes the original Collings hardshell case and case candy shown.

The City Limits combines a Jet Black flamed maple top with Honduran mahogany back, sides, and neck, giving it a classic look and a ton of tonal character. The lightweight mahogany construction and hand-set mortise-and-tenon neck joint give this guitar excellent resonance, sustain, and response.

The aged finish and hardware add a naturally broken-in look, while the ivoroid binding, rosewood fingerboard, ebony headstock overlay, pearl dots, and nickel Gotoh tuners with ivoroid buttons give it the refined appearance you'd expect from Collings. The high-gloss nitrocellulose lacquer finish ties everything together beautifully.

The real highlight, though, is the pair of cream ThroBak P-90 pickups. They have an incredible combination of clarity, punch, warmth, and bite, and they respond extremely well to picking dynamics and volume changes. The 50s-style wiring, CTS 500K pots, and Juniper Vintage Yellow caps round out a very well-thought-out electronics package.
