JF-322 Wow Wah

The JOYO “Ocho” is an octave pedal, as the name suggests. The controls are as simple as can be: you can control the level of both octaves with the OCT1 and OCT2 knobs and the overall volume with the LEVEL knob, that’s it really. You can dive into wide and rich sound textures that make your guitar sound larger than life! And, as most of our pedals, the Ocho is also True Bypass.

R-29 Gloam

Mit dem Joyo R-14 Atmosphere Reverb präsentiert der chinesische Hersteller als Teil der neuen “Revolution Series” ein Hallgerät mit neun verschiedenen Effekt-Modi und einigen spannenden Extras. Joyo ist vielen Gitarristen ein Begriff, wenn es um günstige Interpretationen bekannter Effektklassiker geht. Die vierte Generation seiner Pedale geht dabei in Sachen Verarbeitung und Design einen großen Schritt nach vorne, ohne jedoch den Preis aus den Augen zu lassen.

Chinese builder Joyo has been making pedals for a very long time but their super-affordable devices were somewhat frowned upon by stompbox connoisseurs, until Mr. JHS posted, in May 2020, this video declaring their 2018 Revolution Series “the perfect budget pedals.”
Atmosphere Reverb is – as far as we can tell – the most affordable multi-mode reverb with more than 3 algorithms (it has 9). Three traditional modes (Spring, Church and Plate) are followed by 6 super-creative ones, with names as abstract as Comet, Forest, Pulse and Rewind.
