The Joyo JF-15 California Sound is an overdrive pedal from Joyo. Joyo positions it as an amp-style drive: the maker says it delivers "the sound of the Mesa Boogie MKII amplifier and get lots of natural and focused rock tones"1. It sits in Joyo's line of compact, budget-priced stompboxes that take a famous amplifier's character as their model.
The pedal is built in an aluminum alloy casing with a stoving varnish finish, and it is light at 390g1.
What it does and how it sounds
Joyo describes the California Sound as a Mesa Boogie MKII-style pedal, aimed at "natural and focused rock tones"1. For a player, that means it is voiced for the high-gain American rock sound associated with that amplifier rather than the midrange hump of a Tube Screamer-style circuit or the tweed-style character of pedals like the Joyo JF-14 American Sound.
Power and current draw
The JF-15 runs on a 6F22 9V battery or a DC 9V adapter1. Its running current is 6mA1, which is low by pedal standards, so it places little demand on a shared or daisy-chained power supply and a battery lasts a long time.
Joyo lists both a battery and an adapter as power options, so the pedal works off-board as well as on a powered pedalboard.
