The R-18 CHOPPER-Z is an amp simulation pedal from JOYO. JOYO describes it as "a high gain amp simulation pedal that brings you modern metal sound"1. It sits in the wider family of speaker simulation pedals: instead of only shaping gain like a distortion pedal, it models an amplifier and a speaker cabinet, so it can feed a power amp, a PA or a recording chain directly.
What it does
The pedal combines three things in one box: a high gain amp voicing, a 412 cabinet simulation, and a built-in noise gate. JOYO sums it up as: "It features 412 cabinet simulation, 3 different output modes and noise gate"1. The cabinet simulation means the pedal can be the last stage before a mixer or interface, and the noise gate helps keep high gain settings quiet between phrases.
The three output modes let the player choose what the pedal sends downstream, which is what separates an amp and cab simulator from a plain drive pedal. JOYO has not published the details of each mode on the product page, so the manual is the place to look for how they are switched1.
Manual and documentation
JOYO publishes an R-18 manual as a PDF download on the product page. The manual file was made available on 27 July 20221.
