I have tried several modelling amps Katana, Mustang which has some good tones. Listening to this review on the NUX 20 , really caught me off guard, for those looking at a practice modeling amp, i would definitely check this out.
Sounds good. All i use and have anymore are Modeling Amps.2 table top amps,a Boss Dual Cube and a white Positive Grid .plus 1 Katana MK2 50.All sound great.
