it's crackley when turning the knobs. Works sweet for a jam in the shed set the drummer up with the extention speaker works a treat. 1 mike straight in or a little mixer for more that one mike. Great cheap rehearsal set up. Went shopping yesterday and checked out PA gear there was plastic junk and anything decent was expensive. I know a dude who fixes things in New Lynn can pass on his info could be a good cheap fold back set up. Say that works fine just a bit crakly on the pots.
