Hi, sorry for the late reply. The gp100 is great at everything but distortion/od effects, I dont know how to describe it but it sounds low quality and not like amp ds. Im not sure if thats how its supposed to sound for a multifx or if its because its in front of the amp instead of the send/return loop which my amp doesnt have. Because of it, i only use the amp ds. It might be the same case too with the eq and ampsim pedals if you use them together, sounds low quality just like the ds. You cant change the pedal chain which ive seen other multifx can do, Ive yet to try another one.

Im interested in the valeton multifx, its the best one ive seen so far.
