The Korg TUBE FUZZ (FZ-S) is a fuzz pedal built around Nutube, Korg's miniature vacuum tube technology. Korg describes it as a fuzz using Nutube that lets players enjoy sounds ranging from light distortion to wildly untamed fuzz1.
Korg positions the FZ-S as a different animal from its earlier OD-KIT pedals. According to the maker, it delivers a weighty sound with a character all its own, along with the rich harmonics that Nutube makes possible2. For a player, that means a fuzz whose core tone comes from an actual tube element rather than the usual transistor or op-amp clipping, which is the selling point Korg itself emphasizes.
What Korg says about the FZ-S:
- It is a fuzz built on Nutube, the company's miniature vacuum tube2
- It covers sounds from light distortion to wildly untamed fuzz1
- It has a weighty sound with a character all its own2
- It offers the rich harmonics that Nutube makes possible2
Korg lists the FZ-S on its custom craft effects kit pages, where it appears alongside the company's other Nutube-based builds1. It is positioned as a different animal from Korg's earlier OD-KIT pedals2.
The FZ-S sits in the fuzz lane, but its Nutube core sets it apart from conventional fuzz circuits built on transistors or op-amps. Korg itself frames the tube element as the source of the pedal's weighty tone and rich harmonics2.
