Extremely versatile switching and feedback looper
The M.A.S.F. Halothan is an interesting pedal capable of doing feedback loops switching and more. Depending on how you hook everything up, you can make an effect loop / bypass device, an A/B/ selector, a feedback looper, a multi-output splitter and muter as well as anything else you can think of! Operates with a standard 9-volt battery or a standard 9-volt DC power adapter with a 'barrel' type negative center tip. We recommend the Visual Sound 1 SPOT.
