I plan to build a simple overdrive circuit with a buffered wet/dry pot at the output. I'm thinking opamp based with diodes in the feedback similar to the tube screamer and others. However these circuits need some filtering to sound good which induce phase shifts that may be problematic with the parallel wet/dry idea.
One idea might be to compensate the phase shift with some kind of all-pass circuit. Ideally I would like to have a tone control of the overdriven signal but this would also mean the phase will shift differently..
Another idea is to build an overdrive preamp with tubes instead and skip the wet/dry thing.
Any thoughts?
