Introduction
Congratulations and thank you for choosing the FRYETTE
Boostassio
®
Tube Power Boost!
As a player, you are constantly searching for new sounds and new
ways to improve your existing setup. We understand the constantly
evolving nature of artistic creativity and the search for the perfect
sound to complement your musical vision.
Boostassio
®
is unique among pedals in general and tube pedals in
particular. It utilizes an EF86 “Pentode” type preamp tube rather than
the typical 12AX7 “Triode” type. The EF86 produces power amp
harmonic qualities not normally present in a triode tube design and
therefore delivers real amp qualities similar to that which you would
experience with a cranked, low powered vintage tube amp.
How it works
Most boost pedals, in fact most pedals in general, operate at very low
voltages which typically limit dynamic range. Dynamic range is the
ability of a device to react to and reproduce large changes in volume or
string attack. If you hit your strings hard and the tone seems thin and
squeezed rather than fat and snappy, you may be experiencing com-
pression due to lack of dynamic range.
Boostassio
®
is a high-voltage pentode tube design which produces
greater dynamic range than a typical pedal. This coupled with a vari-
able bias control produces not only a range of cool distortion effects,
but does so with the clarity of a clean amp. As a result, you will be able
to hear all of the notes and harmonics in a complex chord pattern as
well as the subtle sonic signatures of your different guitars. You can
also achieve a wide variety of vintage and modern tones at any volume
level.
Because of the unique design and wide dynamic range, Boostassio
®
will work well with any instrument, such as bass, keyboards and it
even makes a great vintage blues harp tone!
Fryette products are renowned for outstanding performance and are
designed and built to last a lifetime. Your Boostassio
®
will require
very little maintenance. The EF86 tube is shock-mounted and will last
