Introduction
Tubes
Thank you for purchasing the Fire Bottleä model
FB-1A. This unique booster pedal features an alltube signal path, modified ‘Harvard’ style tone
control and selectable input impedance specially
designed to enhance the tone of magnetic guitar
pickups. The FB-1A can improve clarity for a bigger,
bolder tone or fatten up the sound of a single coil
pickup to give it the characteristic warmth of a
humbucker pickup. Gain is continuously variable
from 0dB (unity) to a huge 30dB allowing the Fire
Bottle to operate as an audiophile unity gain buffer,
clean boost or push a tube amp into overdrive.
The FB-1A is designed for flexibility, simplicity and
outstanding sound quality. Audiophile grade
components and silver solder are used throughout
the circuit with precision metal-film resistors for lownoise and stability, polyester coupling capacitors for
their ability to resolve fine signal detail and groundplane layout. The result is an outstanding booster
pedal that exhibits a level of purity and natural tone
not found in solid-state germanium or silicon
designs.
Thank you for trusting Effectrode to be your effects
company. We wish you many years of musical
enjoyment from this hand-built, all-tube pedal.
The FB-1A signal path is based on
a NOS mil-spec 6112 subminiature
twin triode tube. Raytheon
(meaning, “light of the Gods”)
developed subminiature tubes for
military applications in the 1950s.
The 6112 tube is manufactured to
meet stringent Mil-E-1 specification
for reliability and designed for long
service life under conditions of
severe shock, vibration (20,000G!),
high temperature and high altitude.
Subminiature tubes represent the
pinnacle of tube technology and offer more consistent
musical performance than early germanium
transistors.
