The JOYO R-19 Avallon is an analog compressor pedal, part of JOYO's R series. JOYO describes it as adopting the classic compressor circuit with better dynamic feedback, and it is aimed at both guitar and bass players looking for a warmer, richer compressed tone1. It sits in JOYO's compressor line alongside the JOYO Dyna Compressor and the Joyo Dr.J CompDriver.
Controls and what they do
The Avallon keeps its control set small and focused. JOYO lists three knobs, RATIO, ATTACK and RELEASE, which it describes as giving precise control over those compressor parameters, plus an independent signal input/output control for setting the overall level1.
| Control | What it does |
|---|---|
| RATIO | Sets the amount of compression applied to the signal1 |
| ATTACK | Shapes how the compression responds to the start of notes; JOYO says adjusting it helps obtain a warmer and richer tone1 |
| RELEASE | Shapes how the compression lets go; adjusting it with ATTACK is JOYO's suggested route to a warmer, richer tone1 |
| Input/Output | Independent signal input/output level control1 |
JOYO's own description of the intended result: whether playing guitar or bass, "you'll obtain much warmer and richer tone by adjusting the ATTACK and RELEASE knobs"1.
Power and setup
The pedal runs on 9V power1 and draws 120mA according to RockBoard's PedalPedia entry2. That draw is high enough that a shared daisy-chain supply with several other pedals may not have the headroom, so a supply with spare current is worth having.
JOYO's product page currently shows stock of 0 for the R-19 Avallon1, so availability may be limited.
Bass use
JOYO addresses bass players directly on the product page, and RockBoard's PedalPedia entry repeats the same claim: "Whether playing guitar or bass, you'll obtain much warmer and richer tone"2. For players browsing bass pedals, the Avallon is positioned as a compressor that works on either instrument rather than a guitar-only design.
Manual and documentation
JOYO's product page links an R-19 manual in PDF form, dated 2022-05-27 on the page, which covers the pedal's controls and operation1.
Questions
What power supply does the JOYO R-19 Avallon need?
The Avallon runs on a 9V power supply, as listed on JOYO's product page. The page does not give a polarity or connector specification, so use a standard 9V pedal supply and match it to the pedal's jack. At 120mA of current draw it is worth checking that your supply or daisy chain has spare capacity before adding it to a board.
Is the JOYO R-19 Avallon analog or digital?
The Avallon is an analog pedal. RockBoard's PedalPedia entry lists its circuit type as analog, and JOYO describes it as adopting the classic compressor circuit with better dynamic feedback.
Can the Avallon be used with bass?
Yes. JOYO's product page addresses bass players directly, saying that whether playing guitar or bass, you'll obtain much warmer and richer tone by adjusting the ATTACK and RELEASE knobs. That makes it a candidate for players looking at compressor pedals for either instrument.
How much current does the R-19 Avallon draw?
RockBoard's PedalPedia listing gives the Avallon's current draw as 120mA at its 9V supply. That is more than some simple pedals need, so it is worth confirming your power supply has the headroom.
Does the Avallon have a manual?
Yes. JOYO's product page links an R-19 manual in PDF form, dated 2022-05-27 on the page, covering the pedal's controls and setup.
