Do I need to invert phase a second time? Answered
I'm building a guitar pedal and I am inverting phase with the initial buffer (TL072).
I am then splitting the signal into two parts, dry (no effect) and wet (effect). Each of these will be output as separate channels (left and right) and not mixed back to mono.
I plan to send each channel through its own 386 amplifier chip to boost it to a level suitable for headphones.
So, what I am wondering, is, should I use the 386 to invert the phase a second time back to normal? Or should I use an op amp at unity gain to do that before I send it to the 386? Or does it not matter if I am not mixing the two signals back to mono?
