Spider V 20 MkII is the perfect practice amp for any guitarist, whether playing through one of the 16 tonally diverse presets, or dialing in personalized tones with the easy-to-use controls. Each preset contains effects that can be switched in and out stompbox-style using the dedicated FX buttons on the front panel, and there's also an independent Reverb knob.
