The JOYO R-27 SCYLLA is a bass compressor pedal made by JOYO, part of the maker's R series of pedals. JOYO describes it as a compressor "specially designed for bass", aimed at players who want to even out their bass signal and shape how the compression behaves1.
What it does
The SCYLLA compresses the bass signal, and JOYO says its circuit is designed to feature low noise and a high dynamic control range1. Compression evens out the difference between loud and quiet notes, which on bass helps keep a consistent level across the strings and across the fretboard.
The pedal's compression character is set with three knobs. JOYO describes the ATTACK, RELEASE and RATIO controls together as the way to get "various types of bass compression", so the player can shape how quickly the compression responds and how hard it clamps down1.
| Control | What it does |
|---|---|
| ATTACK | Adjusts the bass compression type, together with RELEASE and RATIO1 |
| RELEASE | Adjusts the bass compression type, together with ATTACK and RATIO1 |
| RATIO | Adjusts the bass compression type, together with ATTACK and RELEASE1 |
| TONE | Retains note clarity and makes the tone stand out during live performance1 |
The TONE control is aimed at the stage player: JOYO says it "retains note clarity and makes the tone stand out during live performance", which addresses a common complaint that compression can blur the attack of individual notes1.
Where it sits in JOYO's bass range
The R-27 SCYLLA is one of JOYO's R series bass pedals. The maker's range also includes the JOYO R-26 MONOMYTH and the JOYO R-28 Double Thruster, a bass distortion pedal, along with the earlier Joyo Scylla and the Joyo Tidal Wave Preamp1.
