Schalltechnik04 Vong-Filterung

I sent my PCB to be traced. I know some here snagged kits from Musikding before they disappeared forever. But since Julian is outta the game now, this thread can help gauge interest in seeing the circuit available here.

From the site:
The VONG-Filterung is a multipurpose gizmo; due to the high input impedance (10MΩ) it is applicable for magnetic and piezo pickups.





The VONG-Filterung features:
  • adjustable HighPass-Filter (30-140Hz)
    • 4th Order-Filter -> -24dB/Oct.
      • -12dB/Oct. fixed at 30Hz
      • -12dB/Oct. adjustable
  • adjustable LowPass-Filter (.250-22kHz)
    • 2nd Order-Filter
      • -12dB/Okt. adjustable
  • DI-Out
    • with Ground-Lift-Switch
  • adjustable Boost (up to +16dB) for the 1/4″-Output
  • Polarity-Switch (180°-Phase) for the 1/4″-Output

The Footswitch allows three different configurations:
  1. LowPass-Filter: ON/OFF
  2. Volume-Pot (Boost): ON/OFF
  3. Volume-Pot (Boost) and LowPass-Filter: ON/OFF

The first two options are quite intuitive – though it’s good to mention that there’s no audible difference between LPF=ON@22kHz and LPF=OFF therefore it is not needed to turn the LPF off if it is not wanted; just turn the knob to 22kHz and forget about it.

The third option is quite nice to avoid the a drop in volume if the LPF is set to very low frequencies. That way it is possible to get reggae-like sounds without any volume drops.
