[B-Stock] 3310 VC-ADSR PCB and Front Panel Kit

The performance is perfect. The finish isn't.

This is a B-Stock PCB + Front Panel kit for our 3310 VC-ADSR. While the electronics are 100% perfect and ready for your build, the front panel features minor cosmetic defects—such as surface scratches, slight scuffs, or silkscreen inconsistencies.

• The Deal: 50% OFF the standard kit price.
• The Condition: Fully functional electronics. Minor cosmetic flaws on the panel.
• What’s Included: High-quality 3310 VC-ADSR PCB and "B-Stock" Front Panel. (Components not included).

If you’re looking for snappy 3310 transients and deep modulation options rather than a pristine collector's finish, this is the most affordable way to get a voltage-controlled envelope into your rack.

About the 3310 VC-ADSR

The 3310 is a classic DIY voltage-controlled envelope generator based on the legendary CEM3310 / AS3310 IC. It provides precise envelope shaping with CV control over every stage, making it a powerhouse for dynamic, expressive patching.

Key Features:

• Complete Control: Attack, Decay, Sustain, and Release controls.
• Voltage Modulation: CV inputs with dedicated amount knobs for each stage.
• Visual Feedback: Integrated LED display to monitor the envelope shape in real-time.
• Smart Gating: External gate input or gate-via-bus (selectable via ribbon cable).
• Form Factor: 10HP width; 25mm depth.
