nugget Posted October 24, 2012 Share Posted October 24, 2012 Hi guys Need some help here, I recently got a second hand eden wt405 and adore the tone but recently its started playing up. When its first turned on it occasionally only make a very very quiet distorted sound when dials are all at gig settings. The clip light still blinks if I slap the strings and the tuner out still drives the tuner. It eventually clears after 5-10 mins after fiddling with it. Its not the cab as I've tried it with a spare and pretty sure its not the bass as the tuner and clip light still work. I guess its a problem with the power amp section? Its very intermittent and that's gonna make it tricky to replicate. Any ideas?? Ta Dave Quote Link to comment Share on other sites More sharing options...
MarkBassChat Posted October 25, 2012 Share Posted October 25, 2012 You can easily verify what exactly is the problem by plugging the bass into the Power Amp input. You can also plug the bass into the Effect Return input. Or plug the Preamp Out -> Jack-Jack cable -> to another power amp. It can be caused by many issues; dirty Effect Return jack, or problems with power amp bias. Make the tests and report what you got.

nugget Posted October 25, 2012 Author Share Posted October 25, 2012 Hi Mark Thanks for that, i'll try pluggin bass into those places next time I get it to play up and I've got my swr on standby to try the preamp out. How do you clean the jacks? is it just sprayed with contact cleaner of do I need to actually clean em out?? Ta Dave Quote Link to comment Share on other sites More sharing options...
MarkBassChat Posted October 26, 2012 Share Posted October 26, 2012 Sometimes you may use a contact cleaner, sometimes a sharp knife, and sometimes you need to replace the jack. Mark Quote Link to comment Share on other sites More sharing options...

[/quote] You get some very fine sandpaper, wrap a small piece around the shaft of a Phillips screwdriver and gently sand around the inside of the jack socket. Make sure that anything you sand off drops out of the amp and doesn't go inside. These are great amps. I'd take it to a tech for a full service.
