The Joyo R-05 Maximum is a dual-channel overdrive pedal with an onboard footswitchable boost, announced at NAMM 2019 as part of Joyo's R Series. MusicRadar reported a US price of $58.99 at announcement1.
What it does
The pedal carries two channels of overdrive plus a boost that can be switched on its own footswitch, so the boost can be used independently of the drive channel12. MusicRadar's announcement says the drive channel "promises clearer overdriven tones"1.
The boost function is controllable on a separate footswitch, according to gearnews.com's Jef2.
Controls
gearnews.com describes "four simple controls labelled Volume, Tone, Gain and Boost", with Volume adjusting output level2. On top of those, two toggle switches shape the voice:
| Control | What it does |
|---|---|
| Volume | Adjusts output level2 |
| Tone | Tone control2 |
| Gain | Drive amount2 |
| Boost | Boost level2 |
| Left toggle | Adjusts the mid-frequency1 |
| Right toggle | Chooses between MOSFET and diode clipping options1 |
MOSFET and diode clipping
The right toggle selects between two clipping types, MOSFET and diode, giving two distinct clipping characters from one pedal1.
Price and availability
The R-05 Maximum was newly announced at NAMM 20192. MusicRadar put the US price at $58.99, calling it "an impressive price point"1. In the UK, gearnews.com listed an RRP of GBP 54.952.
The figures above date from the pedal's January 2019 announcement. Current pricing and availability may differ.

Questions
Does the Joyo R-05 Maximum have a separate boost footswitch?
Yes. The boost function is controllable on a separate footswitch, so you can switch the drive channel and the boost independently during a song. That means the pedal can act as a clean-ish boost into your amp, a standalone overdrive, or both at once, without needing a second pedal or a loop switcher on your board.
What is the difference between MOSFET and diode clipping on the R-05 Maximum?
The right-hand toggle switch chooses between two clipping options: MOSFET and diode. Clipping is what shapes the overdriven tone, and having both selectable on one pedal lets you move between two flavors of drive without changing pedals. MusicRadar's announcement describes the right toggle as choosing between the MOSFET and diode clipping options.
How much does the Joyo R-05 Maximum cost?
At its January 2019 announcement, MusicRadar reported a price of $58.99 in the US. In the UK, gearnews.com listed an RRP of GBP 54.95. Prices may have changed since the pedal was announced at NAMM 2019.
What does the left toggle switch do on the R-05 Maximum?
The left toggle switch adjusts the mid-frequency, according to MusicRadar's NAMM 2019 announcement. Together with the right toggle's MOSFET and diode clipping options, it gives you two voicing switches on top of the main Volume, Tone, Gain and Boost controls.
