Aluminum Falcon.
This is hopefully a reference to the Robot Chicken Star Wars parody - because when you look up Aluminum Falcon on urbandictionary.com, Aluminum Falcon refers to the impromptu creation of a prophylactic sheath, using kitchen materials (tin foil).
Researching this pedal yields a few interesting reads about the business practices of Piedmont Custom Electronics and David Danielson, the creator of this pedal. I can't really tell if PCE-FX is still in business, as their website is not up any more.
This particular Aluminum Falcon is the anniversary edition, a limited run of 30 pedals where every step was done by hand, including the etching and drilling of the PCB.
For the creation of this pedal, several NOS components were sourced, including "a certain mythical germanium clipping diode that contains the tears of neutered Unicorns"
Quick refresh about what a Klon is and what it does:
Designed in 1994 by Bill Finnegan, this is a bit of a weird circuit, since it is mainly used by guitar players to push their amp into a creamy sound - but what it does is hard clipping a germanium diode, which is not usually associated with the word 'creamy'.
Let's have another look at the frequency response of the Klon's Tone control:
The tone knob is not a passive treble cut as one might assume - but an active filter, capable of boosting a lot and cutting a little. It is shelving, but starts as low as 250Hz. While this might be the wet dream of a lead guitarist, as a bassist one looks at this graph and realizes that the tone knob has to be handled with caution. Even if the pedal does not cut any lows - when it boosts everything else, it will sound like the lows are cut. This is made somewhat worse by the impact the gain knob has on the frequency response:
There's a solid bump in the 1kHz range when you ride the gain too high, which will further emphasize a perceived loss of low end.
However, both graphs indicate that it's a bad idea to dime everything, but it also indicates that there absolutely are some knob positions where a Klon pedal can absolutely work for bass.
