B4, u buy a new adapter, let me check with my friend again oki? dont want u to waste your money. Cos if u go to visualsound.com, it says that 1spot adapters can power all marshall effects. so let me check with my friend 1st.
I am using the 1 spot to power all my Boss DS-1 , CS-3, DD3, Ibanez TS-9 , Ibanez stereo chorus, Beringer EQ-700, Morley classic wah, Zoom MR-S4B multi track recorder, Boss Dr. Rhythm and a Marshall GV-2 no problem at all .
