FEATURES & CONTROLS MAIN FUNCTIONS & OVERVIEW
This is the CALIFORNIA DOOM, our humble tribute to one of the most popular amps in the
Stoner/Doom community, the SUNN Model T
The circuit utilizes the exact preamp path as the Model T, but we replaced the Tubes with
Fairchild FET J021 Transistors. To spice things up, we add a dirty Booster in the signal path.
You can engage these circuits one at a time, or you can cascade them to work together for
Fuzzier Sounds. If you run both sides at the same time, the order priority is by default. First
the BOOST, then the DOOM.
The DOOM circuit has the same layout of any preamp. It has an EQ, the Gain Volumes for each
channel and the Master Level. This pedal falls in the Overdrive/Distortion Category, it is not a
preamp because its not able to drive a Power Amp alone.
The BOOST circuit it has only a volume. It is a very simple BOOST and you can use it alone
without the DOOM circuit, but beware, it is not a clean Booster, in fact is very dirty.
Anyway, if you are looking for bassier saturated sounds, a DOOM rhythm machine or maybe
even an overdrive with fully equip EQ... You are welcome ;)
LEVEL
Adjusts the Overall Volume of the Pedal. At max In&Out signal are equal level. You can set this
volume to reduce the overall volume when the pedal is activated.
BRIGHT & NORMAL
Set the Gain for the Bright or Normal Channel. These Channels are Always ON and set in
Parallel so the signal goes into both of them at the same time. To turn of one Channel set the
Gain knob of one of them to zero.
TREBLE, MIDDLE & BASS
Passive 3 Band EQ. The positions of each Knob affect the others slightly. The Treble Knob
boost the High Freq. but at the same time reduces the Bass if turned clockwise.
BOOST
This adjust the level of boost. This is an amplification stage so the In&Out signal are not equal
level, you can dime your volume or turn it up.
