Out of the three Wah pedals which Artec produce, the APW-7 would be the most complex. However as with all Wah's, it is incredibly easy to use no matter if you're a beginner or a established musician.
The classic fuzztown has two seperate fuzz channels, which can either be used separately, or combined to give the player a truly unique fuzz sound.
The Artec SE-DDB Duo Drive Blender runs two separate types of distortion in parallel. The two distortions can be adjusted in intensity to create some interesting blended distorted sounds. This pedal lasts forever on a 9 volt battery.
The sound from this has helped me in achieving "the tone in my head". There are so many combinations where it could be used in conjunction with the amps eq.
