I don't get the hoopla behind effects processors. What if you wanna switch say from distortion to flanger, but the 3-5 buttons they give you have other effects? How is that more convenient than just having a bunch of stomp boxes? Please enlighten me.
you can save patches... for example in bank one patch one... you may have sum distortion, delay and a bit of reverb on... and you can save these settings. then you can press the patch 2 button and in that specific bank the patch mite be heavy distortion with auto wah or something i dunno.

so instead of having to press 5 stompboxes to get the effect you want you can just press one button and it changes it all with you.

truble is most effects boards dont offer the quality of sound analogue effects do
