CompIQ YUNA Pro Compressor (without DITOS)

With its Japanese-inspired name (Yu-Na / 優結 / ゆな / ユナ — meaning gentle, kind, superior and binding or gluing), the CompIQ YUNA Pro Compressor Pedal delivers the essential compression and tone-shaping controls that bassists and guitarists love and trust, all packed into an ultra-compact, road-ready aluminum enclosure. YUNA goes well beyond typical offerings with a refined circuit featuring plenty of additional functions and high-grade components that deliver professional sound and lively response without distortions or artifacts. It’s easy to set up and highly versatile, making it one of the most refined and capable clean-sounding compressors available today. YUNA also supports the optional DITOS transformer-balanced output, voiced for warm, vintage-style lows and clear, detailed highs.

Streamlined Compression Controls with Unmatched Performance and Versatility

The CompIQ YUNA Pro is a smooth-sounding, powerful all-analog compressor and soft-limiter pedal for guitar, bass, or any other instrument or audio source. It operates on a standard 9V battery or an external 9-12VDC power supply (not included), making it one of the few pedals still offering a battery option. Like all CompIQ series compressors, it’s built with Burr-Brown™ pro audio FET ICs, low-tolerance metal film resistors, and plastic film capacitors in the audio path, for low noise and accurate frequency response. At its core is the THAT Corp’s flagship 4320 Analog Engine®, which combines a true RMS-level detector with a high-performance Blackmer® VCA. Unlike typical peak detectors, the RMS sensor averages the signal level over time, better matching how we perceive loudness. YUNA’s RMS reference level can be set to -10dBu for strong sources like pro line-level gear, -20dBu for standard instrument signals, or -30dBu for low-output pickups such as single-coil guitars.
