Scotticus Posted February 4, 2012 Share Posted February 4, 2012 Hey all, Got a strange problem with my Shuttle 6.0 that hopefully someone here knows how to fix. Basically, I get an intermittent buzzing sound coming through the Speakon output. When it happens, I've found tapping gently around the top panel will eventually get rid of it, but there's not a specific point to go for that I can locate. The closest thing to consistency I've got is that if I touch the mute button without grounding myself by also touching the metal casing, the buzzing appears every time, so I'm guessing it's something to do with this mute switch being on the blink. All the pots work fine and don't cause the same problem. I've checked for any obvious loose connections on the power and Speakon sockets but no clues there either. If you've had a Shuttle in bits before and can give me any pointers on how to remedy it, I'd be forever in your debt. Cheers Scott Quote Link to comment Share on other sites More sharing options...
icastle Posted February 4, 2012 Share Posted February 4, 2012 (edited) If tapping the casing eventually stops the buzzing sound then the likelihood is that you've got a loose connection in there somewhere. Without experiencing the fault first hand it's, unfortunately, impossible to diagnose whereabouts that loose connection is.

daz Posted February 4, 2012 Share Posted February 4, 2012 I had a similar thing. Never found out what it was, probably a loose connection. Drove me nuts. Had to get rid in the end. Open the top up switch it on and wait and see if you can catch anything if you look closely. Maybe a cold solder blob opening up. ? Use a magnifying glass if nothing is visible with the naked eye. If you are lucky you might find it. The more you know about how these things are built the better chance you have of catching it. Sorry to be pessimistic.

gary mac Posted February 4, 2012 Share Posted February 4, 2012 Is it still under warranty? Not trying to be clever but thought you may not be aware, they come with a three year guarantee. Assuming it's out of warranty may be worth you doing a search on the Talk Bass forum, I believe one of the users on there was involved in the design of the Shuttle 6. He seems very willing to offer advice. Sorry, can't recall his user name. Quote Link to comment Share on other sites More sharing options...

Thanks for the tips chaps. I've followed them best I can, but would be the first to admit that I'm clueless about this kind of thing, so not managed to narrow it down anymore. Mark at Bass Direct has put me in touch with a guy at Fender who reckons he'll diagnose the fault for free and quote a price before starting any repairs. Unless anybody has horror stories or knows of somewhere cheap and reliable in london, I'll drop the Shuttle in the post in the morning.

brensabre79 Posted February 7, 2012 Share Posted February 7, 2012 It says three years on their website... and thats the GB warranty not Bassdirect. See in the bullet points: http://www.bassdirect.co.uk/bass_guitar_specialists/Genz_Benz_Heads_STL6.html Have you ever changed the valve? I read on a US post that the valve housing can be troublesome. My Shuttle had to go back after a month because it made a hissing noise and the volume dropped - when I tapped the top near the valve it cured it temporarily - it went back to Genz.
