This is an idea for a unity gain clipping circuit to be used in a guitar effects unit as a 'distortion' pedal.

Some percentage of a peak detector output voltage feeds into the reference voltage of a clamp.

If the input signal were compressed, the clipping would be relatively uniform. Or if the peak detection capacity were discharged quickly enough.

Could someone please:

  1. Tell me if this idea is idiotic?
  2. Tell me if the polarities of the opamp inputs are correct?
  3. Suggest values for the RC network on the peak detectors?
  • \$\begingroup\$ OD808's clipping circuit without parallel RC network works better (Parallel RC network provides soft clipping). You can Google "OD808 schematic". \$\endgroup\$ – Rohat Kılıç Feb 1 '17 at 15:22

    \$\begingroup\$ I removed your request for having other people simulate your circuit, while editing the markup. If you can draw your circuit, you can simulate it yourself. \$\endgroup\$ – pipe Feb 1 '17 at 15:24

    \$\begingroup\$ VTC - The 2, 3, and 4 questions here are basically asking for a design consultancy to complete the circuit design. This site is not that. Good god even any engineer realizes that you do your own circuit simulations - or pay someone to do it. \$\endgroup\$ – Michael Karas Feb 1 '17 at 15:26

    \$\begingroup\$ @Richard you can download LtSpice for free. A lot of people use that. \$\endgroup\$ – Steve G Feb 1 '17 at 15:34

    \$\begingroup\$ One thing for sure, you cannot monitor (peak detect) the node that you are clipping. \$\endgroup\$ – rioraxe Feb 1 '17 at 19:30
