WELCOME TO THE FAMILY
Congratulations and thank you for choosing the PITTBULL FIFTY/CL Guitar Amplifier!
At Fryette Amplification, we know you are constantly searching for new sounds and new ways to improve your
existing sound. We understand the constantly evolving nature of artistic creativity and the search for the perfect
sound to complement your ever-widening musical vision. Providing the tools to help you to create your own
sonic signature is our primary mission.
The Pittbull Fifty/CL is designed for straight ahead players who prefer to rely on the guitar volume for the clean
sound. Two channels of unapologetic attitude with a 50-watt power plant, deliver thick touch sensitive response
with a decidedly British persuasion. This is a no-nonsense amplifier with a deceptively simple feature set in
which either channel can serve as a Clean, Crunch or Burn channel. The CL’s Red & Green channels are
similarly configured but voiced slightly differently for a wide palate of pristine clean, slightly dirty clean, spanking
crunch and aggressive but harmonically rich overdrive. Combined with an extremely expressive graphic EQ,
this allows for quick and intuitive sound sculpting.
Getting familiar with the Fifty/CL amplifier is easy, so don’t be terribly surprised when you find yourself up and
running in no time. First hand experience and real world application will yield the ultimate satisfaction of finding
your own path of comprehension and self-expression.
