I just bought myself an eden d410xlt and wt550. Great! couldn't wait to get it! However now i have it i think they may be a fault with the amp or cab. I get a buzzing sound comming out of it, this gets louder if i turn up the gain or master volume but is reduced loads when i turn all the treble off. if i touch a metal part of my bass or the amp then it is reduced but can still hear a hum. I don't think its my bass as i have tried it with both my marcus miller jazz and my old ibanez gio and get the same thing happening. any one else experience this problem? obviously having just got the amp im quite reluctant to have to send it back, but if thats what i need to do then its not a problem. could it be a problem with DC voltage and get it checked out by a technition? if anyone could suggest what problems it might be that would be great, or maybe its just me not setting my EQ and levels right!
