MAXON SD9 DISTORSORE

Descrizione

Input signal goes through a simple High-Pass filter into a transistor that’s set up as an emitter/follower (high input impedance – low output impedance).  After this it’s into an Op Amp stage designed to give a gain range of 67 to 567and a Low-Pass Filter with a corner frequency of approximately 1540 Hz.

From here it’s on to a set of opposing-direction diodes to ground and a tone control that is reminiscent of the Boss DS-1 (kind of a Big Muff dual High and Low cut – ending up with a mid scoop that has a high frequency limiting resistor with corner frequencies of 867Hz and 234Hz respectively).

The SD-9’s dual diodes to ground give a crunchier, chewier distortion than the popular 808-style “diodes in feedback loop” configuration.  Likewise, the SD-9’s mid scoop is practically the antithesis of the 808’s infamous mid hump.

After the tone control section it’s through to a volume control and into another E/F transistor to provide a low impedance output and then on to the true bypass switch.

The SD-9 features Mechanical True Bypass switching via a Fujisoku 4PDT switch – Input is switched to ground when bypassed.
