If you are reading this then you are already pondering whether or not you should buy this...Let me give you the answer, BUY IT NOW ! ! ! This is exactly what I needed. I run preamp pedals and a Quad Cortex and the PA50 just gobbles everything up and spits out the tastiest of tones thru whatever cab/speaker/ir you are running it into. It is very very easy to dial in the exact poweramp tone I need for the application be it a standalone preamp pedal or the more complex Quad Cortex. I cannot say enough good things about this, it is absolutely perfection!

Love this pedel - sounds amazing! it chugs!!!
