"Korg" AJ,

You have correctly analyzed my incorrect assumption of an echo defect after taking your suggested test. I found (and I was wrong originally) that not ALL F3 & F4 voice had excessive echo on them. Therefore, your original suggestion of poor pre-set effect setting maybe the culprit. I am very relieved that I will be able to adjust this value (once I learn) thanks to you. I am very pleased with the PA80 but I have alot of learning to do and I shouldn't jump to rash evaluations (operator error, not board defects). I will go to the Yahoo group and obtain as much info as I can and hope that I
can learn more and help others. This internet is a great "information source".
