Walrus audio DEFCON4 Preamp EQ Boost

The WALRUS AUDIO DEFCON4 Preamp EQ Boost effect pedal works as a preamp and EQ to meticulously craft your guitar's sound.
Avoid amp tweaking during a live set by using the DEFCON4 to easily switch from single coil to humbucking instruments with a quick twist of the rotary knobs. When the Launch switch is engaged, go into DEFCON 1 and activate a searing boost for your guitar.

Use the Low (IV), Mid (III) and High Band (II) rotary knobs to cut and boost frequencies of your signal. The toggle switches will activate or bypass each frequency. When activated, the corresponding illuminated numbers will turn on. Flip the launch switch to go to “DEFCON 1” and activate a 10db MOSFET boost.

The concept came from how Ryan uses his setup live. He plays a Les Paul but when he switches to a lower output guitar like a Strat, he can’t easily get to his amps to adjust. Hence the idea for the Defcon4. He has it all set to where he wants and all he has to do it turn it on and he’s good to go for the next song.

From tone to knobs, Ryan worked very closely with us on exactly how he wanted it to look and sound. “I want this to look like someone from the 80s was pushing the technology they had available at the time.
