Featuring precise ATTACK, RELEASE, and RATIO controls plus a TONE knob to maintain note clarity, it’s housed in a rugged metal alloy case with ambient LED lighting for a sleek stage presence. Compatible with standard 9V DC power supplies, this pedal delivers professional-grade sound shaping for live and studio use. ## Description The JOYO R-27 SCYLLA is an optical bass compressor pedal that delivers smooth, transparent compression through a genuine light-dependent resistor (LDR) circuit—the same technology prized in professional studio compressors. Six dedicated controls—Attack, Release, Ratio, Tone, Input, and Output—give you complete command over your dynamics. Optical compression naturally evens out volume peaks, adds sustain, and tightens your playing without coloring your core tone. Whether you're playing bass, guitar, or acoustic instruments, the SCYLLA delivers polished, professional sound with remarkably low noise. Key Features: Genuine optical compressor circuit (LDR-based) for smooth, transparent compression with high headroom 6-knob control: Attack, Release, Ratio, Tone, Input, and Output—studio-grade flexibility for any playing style ATTACK adjusts compression engagement speed—fast for smoothing, slow to preserve pick attack transients RELEASE controls compression recovery time—short for tight, percussive basslines, long for singing sustain RATIO sets compression intensity—from subtle 2:1 evening to heavy limiting TONE control—unique timbral flexibility rarely found on compressors at this price: brighten for presence, darken for warmth Independent INPUT and OUTPUT controls for precise gain staging with any instrument Gain reduction indicator LED shows compression activity in real time True bypass (relay-based) for transparent signal path when disengaged Ambient LED lighting with 3 modes: Sync, Always On, or Off—adjustable via recessed switch Part of the R Series—JOYO's latest generation of guitar effects pedals Rugged aluminum alloy housing with classic stoving varnish finish Compact, pedalboard-friendly design: 109×72×48mm, 237g Important: Powered by 9V DC adapter only (center negative, not included). Rated current: 100mA. Battery operation is not supported. A regulated, isolated power supply is strongly recommended for the quietest performance. Quality Assurance: Every JOYO R-27 SCYLLA is tested before shipping. For the quietest performance—especially with high-headroom optical circuits—use a regulated, isolated 9V power supply (not included) and avoid daisy-chaining with other pedals. If you experience a high-pitched whine or hum, first check your power supply—incompatible or unregulated adapters are the most common cause. For best results with compression, start with all controls at noon, set Ratio to 4:1, then adjust Input to drive the compression circuit and Output to match your bypassed volume. If problems persist, our support team is available through your desertcart order page.
