G-Storm Electro Pro VCF Aluminum 3320 Filter Adaptation

The Pro VCF ALUMINUM Panel version is a faithful adaptation of a well-known 4-pole synthesizer filter in Eurorack.  Identical sound and features as the black panel version.

The core of this design lies an Alfa AS3320 filter chip based on the original Curtis. Countless synthesizers used the 3320: Sequential Pro One, Prophet 5 rev 3, Drumtraks, Crumar Trilogy, Stratus, Elka Synthex, some Fairlight CMI, Linndrum, PPGWave 2

All full resonance the Pro VCF can self-oscillate.

FEATURES

• Two selectable filter slopes:original 24 db/oct, and 12 db/oct.
• Two voltage controlled input jacks for frequency CUTOFF w/ signal attenuators.
• A voltage controlled input jack for RESONANCE w/ a signal attenuator.
• Two signal input jacks w/ individual attenuators. At full clockwise, these inputs can overdrive the filter from most eurorack oscillators and audio sources.

INCLUDED | A Eurorack power connection ribbon cable.

NOT INCLUDED | M2.5 or M3 (Doepfer standard) Phillips-head basic zinc rack screws are only provided on special request. Why do I do this? To cut down on rack screws that are wasted in the universe. What's it gotta be? Thousands? Hundreds of thousands? Unused, unwanted. You know the ones I mean | wrong size, wrong color, cheap junk tin, top slot-stripping, rack-rashers, wrong thread count, wrong length, wrong political party, etc. I use thumb screws in 2 sizes myself. So yeah, if you request some M3's from me, I will probably pull the ones from other companies boxes in my closet. You're welcome :D

"Wonderful filter! Running the Neutron oscillators with a bit of noise and S&H to their PWM then through this filter results in a VERY Pro-One sound." –Brian, OR

"At this price point this filter is a must own for a mono set up." -user Stashy, Modular Grid
