Ant Posted March 6, 2015 Share Posted March 6, 2015 if i have a preamp pedal which inverts the phase of my signal, placed in a parallel loop with another of the same pedal everything will be fine, but if i then bypass ONE of the preamps (reverting one side of the loop to the original signal) would it have phase cancellation issues even if the bypassed side is ridiculously low volume (as it isnt running through a preamp) Quote Link to comment Share on other sites More sharing options...

dannybuoy Posted March 21, 2015 Share Posted March 21, 2015 Yes, unless the preamp also inverts phase when in bypass. Phase cancellation won't be so bad if the bypass volume is much much lower than the effected volume though. Quote Link to comment Share on other sites More sharing options...
cheddatom Posted March 23, 2015 Share Posted March 23, 2015 You won't know how bad it'll be until you try it. Generally, for phase cancellation to be really bad, you need two very similar signals out of phase with each other. You'll have one clean, low volume signal, blended with one effected, high volume signal, which are quite different, so hopefully it wouldn't be so bad Quote Link to comment Share on other sites More sharing options...
dannybuoy Posted March 23, 2015 Share Posted March 23, 2015 I would rather modify my switching setup so that this didn't happen though. What are you using? I would also prefer to mute one of the parallel loops with a tuner rather than bypass the preamp and end up with out of phase clean signal coming through which negatively interacts with the other chain.

Ant Posted March 23, 2015 Author Share Posted March 23, 2015 thanks for all the help, in the end i just switched out the LS2 for a COG effects pedal which lets me swap between and blend each preamp Quote Link to comment Share on other sites More sharing options...
