funny things about STEREO pedals
One of the things I realized interesting when using stereo pedals, a lot different from other guitar pedals, is that every stereo pedal that comes after the first stereo pedal, has to be "true stereo" with "discrete stereo inputs and outputs", otherwise you'll experience undesirable mismatched results.
If you only use one stereo pedal and you placed at the very end of the chain, you'll be fine to go without any problem. If you are using more than one stereo pedal you may have a problem due to the fact that most stereo pedals quite often have only a single mono input.
And also, many pedals with two inputs are often not actually "True Stereo" because the two inputs are summed to mono before feeding the stereo processor.
What’s more, when using true stereo pedals, you still have to watch out for phase and other imaging issues.
I find this information to be very helpful because if you're not aware of issues like these, you could easily find yourself spending tons of time trying to correct a phase or stereo imaging issue in other areas that aren't related to core problems. Then once you figure out where the problem comes from, you'll then wonder why... and it won't make sense. Bottom line is you must use "True Stereo Pedals" if you are using more that one.
