Hi all, I went in search of a noise gate and settled on a Boss LMB - 3 Bass limiter Enhancer. (It was a toss up between that and the NS2. LMB3 won because I found a cheap one and couldn't work out the practical difference between the two). Bought it second hand without a power supply. Sticker on it says "Use Boss PSA adaptor only" which Im guessing is the equivalent of "Use only AJAX brand cleaners in your westinghouse washing machine". If I buy a boss one Ive got to order it in. If I can use a generic Ive got plenty lying around. Can I just use any old 9V adaptor or do I need a specific amp /ohm /rad ratings? If so, whats the best? Not batteries. Hate the batteries. But don't want to fry my new stompy. Thanks!
