Description
The Walrus DEFCON 4 puts real EQ control at your feet, letting you sculpt your tone with precision before it hits the rest of your board or the front end of your amp. Rather than a simple boost, this is a full three-band preamp: independent Low, Mid, and High rotary switches give you stepped control over each frequency range, while dedicated toggles let you activate or bypass each band individually. That means you can carve out mud, add sparkle, or push the mids forward without touching the others — ideal for dialing in a specific EQ curve rather than guessing with a single tone knob.
When you need more than shaping, flip on the 10dB MOSFET boost for a clean, transparent push in gain. It’s built to drive your amp harder or wake up a dark pedal chain without smearing your tone or adding unwanted coloration. Placed early in the signal chain, the DEFCON 4 works as a always-ready EQ platform; placed later, it becomes a solo boost or a way to compensate for tone loss across a long pedalboard run.
This unit is an Open Box deal from ProAudioLand — fully functional, in excellent cosmetic condition, and shipped in its original packaging. A great way to add serious tone-shaping flexibility to your board without paying full price.
