Hi everyone:
Today i made a test: i put my MXR Zack Wylde overdrive before my KPA to see what it happens ...... And it was a big surprise! I got a very defined and warm sound, specially for soloing ...... Well, i couldn't believe the sound that i got!
The most important thing is that i was getting with high gain settings, a trebbly sound .... But now, i am getting a full and warm sound, like from a real amp! Goodbye trebbly sound!
I don't know if this trebbly sound was as result of my PA's, but it doesn't bother me anymore, because for soloing and high gain settings, i am using my OD pedal before and getting an awesome and outstanding sound.
I am sharing this experience, because it can be usefull for someone else.
Bye.
