The CMAT Mods Deluxe Signa Comp is a 4-knob boutique guitar compressor pedal known for its warm, transparent, and quiet operation. Expanding on the standard 3-knob design, it adds precise Attack and Tone parameters alongside the core Sustain and Level controls to eliminate unwanted attack spikes and retain low-end clarity.

• Transparent Circuit: Uses matched transistors to keep tone natural without heavy coloration.
• Low Noise Floor: Designed to be exceptionally quiet for a compression pedal.
• Build Quality: Features true bypass switching (EH 3PDT), Alpha pots, and Switchcraft jacks in a standard copper enclosure
