This is a comparison between the newest "MKII" series pedals from Pettyjohn Electronics - the Chime MKII, Iron, MKII, and Gold MKII. Of course these pedals have different features and controls, so I tried to equal them out as far as level, bass and treble, to really focus on the drive/gain character of each pedal. What do you think? Any favorites? Things you observed? Let me know your thoughts in the comments below! And be sure to check out the Pettyjohn website at www.pettyjohnelectronics.com.
