Erschließen Sie das Potenzial Ihrer Gitarre mit polierten Bünden
When you pick up your guitar or bass you want to be inspired, not frustrated by dull, rough frets. Polishing your frets is the simple, high‑impact step that improves sound, longevity, playability and appearance. Fret polishing is a genuine game‑changer — and it's easier than you think.
Why polished frets matter
Better sound
A smooth, mirror‑like fret surface produces a clearer, more consistent tone. Rough or oxidised frets can create scratchy noises and uneven contact with the string. Polished frets let the string glide cleanly, reducing fret noise and string breakage while improving sustain and clarity.
Improved longevity
Polishing removes microscopic pits and grime that accelerate corrosion. Regular maintenance prevents long‑term damage and helps keep frets in service for many years, postponing costly refretting or repairs.
Professional look
Shiny frets make a guitar look cared for and stage‑ready. A well‑presented instrument invites practice and performance — it’s no surprise most pro players keep their frets polished.
Precise playability
A glassy fret top gives you consistent contact for cleaner bends, smoother vibrato and more accurate fretting. Playing becomes more confident and effortless, especially during fast runs or expressive techniques.

FAQ für das FRTLZR Bundpoliersystem
Das FRTLZR Fret Polishing System ist die ultimative Lösung, um polierte Bünde auf Ihrer Gitarre zu erhalten. Es ist ein umfassendes Set, das den Glanz und die Glätte Ihrer Bünde wiederherstellt. Mit den enthaltenen Politurmaterialien und Werkzeugen entfernen Sie Anlauffarben und Oxidation und sorgen dafür, dass Ihre Bünde optimal aussehen und funktionieren.
"Mit dem FRTLZR Fret Polishing System werden Ihre Gitarrenbünde wie neu oder sogar noch besser glänzen, und Ihr Spiel wird neue Höhen erreichen." - Johann, Gitarren-Enthusiast
Die Häufigkeit des Polierens der Bünde hängt von Ihren Spielgewohnheiten und dem Zustand Ihrer Bünde ab. Als allgemeine Richtlinie empfehlen wir, das System alle 3-6 Monate zur Pflege zu verwenden. Wenn Ihre Bünde jedoch stark angeschlagen sind oder Anzeichen von Oxidation aufweisen, sollten Sie sie häufiger polieren. Manche Benutzer polieren ihre Bünde sogar bei jedem Saitenwechsel.
"Regelmäßiges Polieren der Bünde ist der Schlüssel zum Erhalt eines brillanten Gitarrentons und einer hervorragenden Spielbarkeit." - Tim, Gitarrentechniker
Auf jeden Fall! Unser Bundpoliersystem ist für alle Gitarrentypen geeignet, einschließlich elektrischer, akustischer und Bassgitarren. Es eignet sich für verschiedene Bundmaterialien, wie Neusilber, Edelstahl und Messing. Außerdem deckt es eine breite Palette von Bundbreiten ab, von normalen 2,0 mm bis zu Jumbo 2,8 mm und wahrscheinlich noch ein bisschen mehr.
"Egal welche Art von Gitarre du spielst, das FRTLZR Fret Polishing System bietet dir alles." - Dennis, Gitarrist
Unser System eignet sich zwar hervorragend zur Wiederherstellung des Glanzes und zur Beseitigung kleinerer Schönheitsfehler und Kratzer, kann aber tiefe Einkerbungen nicht beseitigen. Bei größeren Schäden an den Bünden empfehlen wir, einen professionellen Gitarrentechniker zu konsultieren, es sei denn, Sie vertrauen auf Ihre Heimwerkerfähigkeiten.
"Für makellose Bünde ist das FRTLZR Fret Polishing System Ihr bester Freund. Aber denken Sie daran, dass tiefe Einkerbungen besondere Aufmerksamkeit erfordern." - Tim, Gitarrentechniker
Auf jeden Fall! Unser Fret Polishing System wurde sowohl für Anfänger als auch für erfahrene Gitarristen entwickelt. Eine klare Anleitung führt Sie durch den Prozess und macht es Ihnen leicht, professionelle Ergebnisse zu erzielen. Selbst wenn Sie noch keine Erfahrung mit dem Polieren von Bünden haben, werden Sie erstaunt sein, wie einfach es zu bedienen ist.
"Man muss kein Profi sein, um mit dem FRTLZR Fret Polishing System Ergebnisse auf Profi-Niveau zu erzielen." - Ecaterina, Anfängerin Gitarristin
Die Langlebigkeit der Politurmaterialien hängt von der Häufigkeit der Verwendung und der Größe der Bünde Ihrer Gitarre ab. Im Allgemeinen haben unsere hochwertigen Papiere bzw Leinen eine lange Lebensdauer und ermöglichen zahlreiche Poliervorgänge, bevor sie ersetzt werden müssen. Wenn Sie mehr benötigen, können Sie zusätzliche Poliergitter separat bestellen.
"Das FRTLZR Fret Polishing System ist eine Investition, die dank seiner langlebigen Verbindungen immer wieder aufs Neue überzeugt." - Steve Gitarrenpflege-Enthusiast
Wir engagieren uns für den Umweltschutz. Unser Fret Polishing System wird mit Hilfe der 3D-Drucktechnologie hergestellt, wodurch die Abfallmenge minimiert wird. Die wiederverwendbaren Komponenten und die umweltfreundliche Verpackung tragen zur Reduzierung der Umweltbelastung bei.
"Mit dem FRTLZR Fret Polishing System können Sie sich an makellosen Bünden erfreuen und ein gutes Gewissen haben." - Tim, Gitarrentechniker
Unser Fret Polishing System ist für alle Arten von Griffbrettern geeignet. Wir empfehlen jedoch, den Kontakt mit beschichteten oder lackierten Griffbrettern zu vermeiden, um mögliche Schäden an der Beschichtung zu vermeiden. Um das Griffbrett während des Poliervorgangs zu schützen, können Sie etwas Klebeband oder einen Fretboard Protector verwenden, um Kratzer oder Schäden zu vermeiden.
"Ein wenig Vorsicht hilft, das Griffbrett der Gitarre zu schonen." - Tim, Gitarrentechniker
