Leading the classic bass guitar to the highest level of Quality and Performance

For years, many J-Basses inspired instruments have been available but now with the F-Clef Bass, an instrument capable of combining the sound and feel of the best exemplar of the "classic" basses from the 60's and the 70's with the quality experienced before only in the finest works of world class luthiery has finally taken shape!
In a nutshell.. The finest components and craftsmanship in the U.S.A.Hands down!Here is what we have achieved with our bass from a player's perspective:
- A true"vintage" sound and feel!Yes,even in a 5 string!
- Useful real world "Tone Quality": eveness, clarity and articulate in all registers.
-String to string balance, sensibility to the bassist's playing and dynamics.
- Superb playbility and comfort: string flexibility.Ultra low settings fast and effortless "D" shaped neck profile.

The woods selected for each instrument are aged and come from a hand picked stock billets, to acquire the maximum acoustic resonance. We utilize alder and ash for our bodies according to the vintage philosophy and sometimes mahogany on the "Elite" styles basses.
- Alder bodies deliver a rounder, deeper tone
- Ash bodies: faster attack, more mid-rangy growl
- Mahogany: warm low end, structured mids and high mids
The weight of these woods can vary upon the customer's request: lighter body woods deliver a smoother attack and deeper resonance in the low end; heavier woods deliver faster attack, punchiness and more structured mids. In stock instruments usually are medium weight.
Woods of choice for the fingerboards are Indian rosewood, Bolvian rosewood, sugar maple, birdseye maple, Indian ebony and macassar ebony; we feel that fingerboard is an extremely decisive factor for the final sonic result.:
- Maple fingerboads: clear and defined lows, growly mids and bright highs
- Rosewood fingerboards: warmer lows and darker mids
- Ebony fingerboards: very focused and even tone; full range with a slightly compressed and very lyrical attack. We recomend this fingerboard to achieve by definition a variety of modern tones.
Any wood combination on F-Clef basses delivers its own character and behaviour.Still, undeniably keeping the fundamental vintage flavour.Check some examples of these tone varieties in our Audio Gallery

The Fclef passive/active electronics In passive mode the Fclef reproduces accurately and faithfully the old J-Bass. In active mode, the passive tone control is also usable maintaining an absolutely clean and natural tone when flat.
As you start tweaking the preamp.You will realize it yields an array of powerful modern tones without hindering the instruments true vintage bass character.

We chose Seymour Duncan as our signature sound.The "Seymour Duncan Custom Vintage Single Coils" matches the instrument's character still delivering extremely clear, hi-defined, and dynamic response that's always natural and true to the acoustic sound of the different wood combinations. Other brands and types of pick ups can be choosen on an individual custom-order basis.
Every aspect of the construction from neck carving truing, neck/body joint and hardware components, have been carefully designed, realized and are some of the reasons why your first experience when playing an Fclef is tactile familiarity and quality craftsmanship at hand.
