I also have a VS100 but it works just fine. Man along with a DS1 (Boss dist) I have an amazing solo tune and for rythm only amp dist. Great tone, hell amazing for pinchin´ screams a la Zakk Wylde. Clean along with Boss CH1 Chorus works damn fine. Great amp and best of all is that I got VS 100 and one 4x12 box for 4.000 swedish crowns. (1$ is aprox 9-10 Skr.) Nica price!!
