Introducing C-Note Tonic

C-Note Tonic

The fretboard conditioner for players who refuse to settle.

Formulated from the finest natural oils and waxes, C-Note Tonic nourishes, protects, and restores every fretboard — from vintage rosewood to modern ebony. Because your instrument deserves the same care you put into your playing.

Why C-Note Tonic

The difference is in the detail.

Deep Nourishment

Penetrates the grain, not just the surface.

Most conditioners sit on top. C-Note Tonic is drawn into the wood at a molecular level, restoring moisture where it matters — preventing cracks, warping, and the dull, lifeless feel of a neglected board.

Zero Residue

Clean hands. Clean tone. Every time.

A conditioner that leaves buildup is a conditioner that changes your feel. C-Note Tonic absorbs completely, leaving nothing behind but a fretboard that plays exactly as it should — smooth, fast, and responsive.

All Wood Types

Rosewood, ebony, maple, pau ferro — covered.

Different woods have different needs. C-Note Tonic's balanced formula works across every unfinished fretboard wood, adapting to the grain without over-saturating softer woods or under-nourishing denser ones.

Application

The Ritual

Three steps. Five minutes. A fretboard that plays like new.

Clean the board

Remove strings and wipe the fretboard clean with a dry cloth. Remove any buildup from the fret slots and around the frets themselves.

Apply C-Note Tonic

Apply a small amount to a clean cloth and work it into the wood along the grain. A little goes a long way — you're feeding the wood, not flooding it.

Let it absorb

Allow 3–5 minutes for full absorption. Wipe away any excess. Restring and play. You'll feel the difference immediately.

From the players

Trusted by those who know.

I've been setting up guitars for 22 years. C-Note Tonic is the first conditioner I've used that I'd actually recommend to a collector. It does exactly what it promises — nothing more, nothing less.

Master Luthier, Nashville

My '64 Telecaster's fretboard was starting to look like driftwood. Two applications of C-Note Tonic and it looks like it just came out of the factory. Incredible product.

Vintage Guitar Collector

The feel under my fingers changed immediately. Faster, smoother, more responsive. I don't know what's in this stuff but I'm never going back.
