Hi!
Just like to know if it's possible to use a standard circuit for mid boost/cut to have it to boost only ?
Like a circuit with a gyrator to a op amp +\- inputs for boost / cut.

Anyway, I just want it to boost......

Hope U understand what I'm looking for.

Thanx

Use a pot of half the value that the cut/boost is and pad it with the same value resistor so you cannot go into the cut portion of the range.

(Hope that makes sense!)

I just built the EMG SPC circuit, with excellent results. Response is (more or less) flat if the pot is fully ccw.
