I am thrilled with this box. It is very very easy to get it to sound good! It is always in my effects chain. This box and the TS-9 are like colouring pencils to me, they just colour the sound in for me leaving the original tone of the guitar/amp intact.
2 intensity switches, one for width, the other for height, = 4 different settings.
Great sounding reverb unit. Very easy to dial in some beautiful reverb sounds.
