Please don't answer 'Yes" straight away.......
I have just bought an envelope filter to have a play with (Boomstick Bottom Feeder). Simple stuff. Plug it in, connect to the amp and voila!! or so I thought.....
When I turn it on it buzzes very loudly through the amp and cuts off the bass! so, thinks I, maybe I have been stupid and connected it wrong, quick switch of the cables, same thing.
Bit of Research on the net. Any 9V power supply will do.. I am using a 9V power supply.
Anyone know what is wrong is the filter not working properly? I have my doubts about the power supply.
