Oct-2010

What about putting some smoothness and wah wah feeling on the instrument...Just take a MoogerFooger MF-101 Lowpass Filter from Moog !

Specifications :

Features :

* CUTOFF rotary control, which varies the filters cutoff frequency over an eight-octave range. 
* RESONANCE rotary control, which varies the shape of the filters response, from pure lowpass to actual oscillation. 
* ENVELOPE AMOUNT rotary control, which adjusts the amount that the input signals envelope sweeps the filter cutoff frequency. 
* MIX rotary control, which crossfades continuously from unfiltered to filtered audio. 
* DRIVE rotary control, which adjusts the gain of the audio input. 
* SMOOTH-FAST rocker switch, which chooses between smooth and fast envelope follower response. 
* 2-POLE 4-POLE rocker switch, which chooses between 2-pole (bright) and 4-pole (deep) filter frequency 
* response. 
* LEVEL, a three-color LED that is used to set the DRIVE control. 
* ENV, a LED that indicates the strength of the envelope voltage. 
* BYPASS, a two-color LED that tells whether the filter is on or bypassed. 
* ON/BYPASS, a rugged, smooth-acting stomp switch.
