Stewmac FTW
Great tool. I considered the upgraded one but couldn't pull the chord due to the large price difference. Stew mac is the Snapon of Lutiher tools. Expensive but worth it. I do but Stewmac tools when on sale and they have sales often. you will never be disappointed with Stewmac. Buy with confidence because if any tool fails or breaks they will replace it.

Gold Standard of Fret Rockers
The StewMac fret rocker is a substantial piece of steel. It is solid with four machined sides that are perfectly flat. With a little practice you can detect the slightest variations in fret height. I’ve used this fret rocker on my Gibson Les Paul Modern, PRS SC-245 and a Fender Stratocaster. It works well on across different scale lengths. Are there cheaper fret rockers out there that are just as good? Maybe, but I haven’t spent much time looking. My guitars are high quality instruments and I only use high quality tools and that’s what StewMac delivers.

Top Quality!
If you want the same quality luthiers use, this is it. Spend the money. You won’t regret it.

The StewMac Fret Rocker Tool and the Love it!! Guitar lovers this is a fantastic buy:)
The StewMac Fret Rocker tool is one of the most essential and unique gauges available. Easily find “high” frets by comparing to those on either side of the target. Can be moved horizontal along fretboard and vertical across from sting to string to find “high” spots causing annoying buzz. Takes all the guesswork out of fixing fret level issues. Want to make a great impression to a family member or anyone you care . Great gift -StewMac Fret Rocker - The Original Stainless Steel Fret Rocker 4-in-1 Mini Straightedge, etc. Very reasonable priced.

expensive, but accurate
Seems to be well machined and accurate. Be aware that you need to place the flat edges DIRECTLY over the frets you are testing. Seems obvious, but it is easy to tilt the tool at an angle and get inaccurate results.

Se espera algo mejor por el precio.
Es caro para lo que es?Pues si, pero en apariencia viene bien acabado, aunque no es perfecto (tuve que llevar a rectificar ya que según porque lado midiera en un mismo traste daba medidas diferentes), al menos en mi caso.Pero mucho mejor que los orientales de bajo precio

Expensive, but it is an actual fret rocker
4 stars because €45 it is very expensive. However, unlike rough metal sheets resembling a fret rocker which you can get for €6, this one is an actual fret rocker.

Piacevolmente sorpreso!
Difficilmente lascio una recensione, però in questo caso sì. Sono stato sorpreso perché l’articolo è in perfette condizioni, originale, spedito il giorno dopo è arrivato molto prima del tempo previsto. Complimenti!

Klein aber fein! Unverzichtbares Meßgerät für den (Hobby) Guitar Tech!
Hatte unlängst bei meinem neuen Fender Neck ein Schnarren durch einen zu hohen Bund festgestellt. Da ich schon lange vorhatte mich an das Thema Fretleveling praktisch ranzumachen (z.B. liegt ein neubundierter Top-Hals seit ca. 25 Jahren im Keller und wartet auf Leveling) war jetzt endgültig der Zeitpunkt gekommen zu starten. Ich stellte schnell fest, dass die Billigversionen des FretRockers bei Thomann und Co nicht für ernsthafte Arbeiten taugen (Seiten nicht richtig plan) und habe mich schnell für dieses etwas teurere Teil vom legendären Platzhirsch Stew Mac entschieden. Allerdings die Frage an Thoman und Co: WAS ist so schwer daran eine 100% ebene Fläche zu fräsen??? Das habe ich in meiner Ausbildung als Zerspanungsmechaniker damals ständig und mühelos gemacht (bin schon lange raus sonst hätte ich mir das Ding selber gemacht) Egal, wie erwartet klapperte der FretRocker am vorher* schon verdächtigen Bund (Saiten in Standard Stimmung E noch drauf/Hals mit leichtem ca. 0,3-0,4mm Relief). Danach konnte ich den Bund mithilfe des FretKissers ganz bequem abtragen, danach mit der Bundfeile von Thomann (Göldo) crownen/abrunden und schließlich mit Schleifpapier/Stahlwolle polieren. *Tipp: Erst mit Saiten im Wunschsetting (Saitenhöhe,korrekte Oktavreinheit,Neckadjustment etc) jeden Bund anspielen und die für das Schnarren verantwortlichen Bünde mit Edding markieren - dann mit dem FretRocker gegenchecken. VORHER natürlich andere Faktoren für das Buzzing ausschließen (Sattel,Bridge etc) Ergebnis: funzt und kein Schnarren mehr Fazit: Teuer,akkurat ABER gehört (zusammen mit dem FretKisser) in jede Gitarristen-Toobox!
