bassfan Posted April 7, 2009 Posted April 7, 2009 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. Quote

bassfan Posted April 7, 2009 Author Posted April 7, 2009 Not sure about the earth loop.. quite possible. I have checked the Power supply and it's AC. I assume I need a DC one then. My knowledge of electrics is on par with my astro physics. Quote
bremen Posted April 7, 2009 Posted April 7, 2009 [quote name='bassfan' post='456189' date='Apr 7 2009, 10:09 AM']Cheers guys.. one on order!!![/quote] Fingers crossed - you might have toasted the pedal with the AC supply. Hope not, let us know. Check the polarity of the DC supply, ie whether the tip of the plug is + or -. Hopefully it'll be marked on the pedal and adjustable on the supply. Quote
bassfan Posted April 7, 2009 Author Posted April 7, 2009 no marks on the pedal .. I'll keep you posted Quote
Mr. Foxen Posted April 7, 2009 Posted April 7, 2009 If you have a 9v AC wall wart going, Chiseerkind was after one. Quote
xgsjx Posted April 7, 2009 Posted April 7, 2009 Not sure about the Boomstick, but 98% of pedals have a - tip (Moog's are + tip). You might want to check this. Quote
lemmywinks Posted April 7, 2009 Posted April 7, 2009 I had a similar problem with a couple of pedals, turns out i wasn't using a regulated power supply, just a generic cheapie. Tried it with a proper Boss one and all was good! Quote
bassfan Posted April 9, 2009 Author Posted April 9, 2009 New power supply arrived yesterday. All working fine... Thanks guys. Quote

Toasted Posted April 15, 2009 Posted April 15, 2009 You were very lucky not to toast the pedal with the AC. Quote
