The DEFCON4 Preamp Booster Pedal by Walrus Audio works as a guitar preamp pedal and equaliser pedal to meticulously craft your guitar’s tone and avoid tedious guitar amplifier tweaking during a gig by using the DEFCON4 to switch from single coil to humbucking instruments with a twist of the rotary knobs. There is also the Launch switch which, when engaged, activates a signal booster for your guitar. This is Defcon 1, a 10db MOSFET boost. It is also possible to shape the sound further using the Low, Mid and High Band rotary knobs to cut and boost the guitar signal frequencies. There are also toggle switches which can activate or bypass each frequency. As each switch is activated the corresponding defcon light will illuminate, defcon 2-4.
The use of an isolated effect pedal power supply is recommended for powering all Walrus Audio Pedals, daisy chain power supplies are not recommended. Our site includes many more Walrus Audio effect pedals. and boutique pre-amplifier pedals to consider.

About Booster Pre-Amp Pedals
A guitar pre-amplifier pedal is is used in the input section of the guitar signal chain to shape and boost the signal before it enters the guitar amplifier input. There are many styles of guitar pre-amp pedal that have a specific style or tone. Generally features will include shaping the tone and also boosting the gain. In some ways they can also be similar to a booster pedal and may also be able to be used as a DI pedal.
A booster pedal (or driver pedal) is the simplest of all gain-based pedals, boosters do what they say. Taking the signal from the guitar pick up and boosting the signal. A boost pedal acts like an extra gain stage on the amplifier input. If used correctly a booster pedal can be a very versatile addition to your guitar pedal board adding extra flavor to the guitar signal chain and overall sound. Guitar booster pedals were the earliest pedals to be launched, being marketed as treble boosters. In the 60s, many famous players used treble boosters to push their valve driven Marshall guitar amps and Vox guitar amps to achieve a smooth, natural-sounding distortion. Afterwards, overdrive pedals and distortion pedals were introduced giving extra functionality.
Choose your booster pedal wisely, cheap booster pedals can result in a harsh distorted sound. Consider a mid-priced or more expensive boutique booster pedals as made by boutique pedal makers with hextra circuitry to shape the complete guitar sound. Models to consider include the Keeley D&M Drive Pedal, the Fulltone OCD Obsessive Compulsive Drive, the Blackstar HT Dual Booster Pedal, the sleek looking Danelectro Billion Dollar Boost and the Electro Harmonix Screaming Bird Pedal.
