Lately I've been thinking about puting a switch in the EH-DrQ (or DrQuack, 'cause it's a very good mod)so I could change the direction of the filter, just like the mutron does. For what I recall, in the envelope detection part of the mutron circuit you use a dpdt switch for adding a resistor to the inverting input and a voltage divider to the inv input of the opamp that drives the led.
How could achive this in the DrQ/DrQuack circuit?
Anybody tried modding this way?
