Well, in my home studio it is doing a very good job for only 10€.
(Also, it's a plan B for my guitar rig. Used it on some gigs when space was sparse.)
I roughens off the edges of the somewhat dry Lead sound, when I want it to.
The effects I have enjoyed mostly so far are; tube preamp, reverb, chorus, delay ... also I get some kind of stereo-ish feeling?
Kind of takes me back to the 80:ies, when I was a Roland guy.
Dramatically widens the use of the Lead. Time machine?
