Demo of the Pettyjohn Chime Overdrive.

My take:
The Pettyjohn Chime is a low to medium gain overdrive which just CHARMED me from the minute I plugged it in. This thing sounds EXPENSIVE. Just beautiful bell-like, chimey, Vox-y, bright (but not harsh), pretty overdrive tones oozing out of this thing. Even with my Telecaster on the bridge pickup, it never really got "harsh". Get one! No brainer!
