nugget Posted January 3, 2012 Share Posted January 3, 2012 Hi Last few gigs my swr head has been playing up and last night it was very bad. It sounds like there is a load of reverb. It's not echo in the room and it's not the bass or cab. There isnt a reverb unit in the head and it's making everything sound very mushy and un-defined. Anyone got any ideas??

BassBod Posted January 3, 2012 Share Posted January 3, 2012 Start by changing the preamp valve...pretty easy to do yourself. Any decent 12AXY/Ecc83 should do (Sovtek or Electro Harmonix are usually the easiest/cheapest?). Quote Link to comment Share on other sites More sharing options...
Beer of the Bass Posted January 3, 2012 Share Posted January 3, 2012 I'd agree, that sounds like a valve gone microphonic. Quote Link to comment Share on other sites More sharing options...
nugget Posted January 5, 2012 Author Share Posted January 5, 2012 New valve fitted and sounds fine at home volume, gonna give it ago at this weekends gigs. Fingers crossed and thanks for the suggestion Ta Dave Quote Link to comment Share on other sites More sharing options...
nugget Posted January 8, 2012 Author Share Posted January 8, 2012 Hey - good news you guys were right, couple of weekend gigs and it's better than ever..thanks Quote Link to comment Share on other sites More sharing options...
BassBod Posted January 9, 2012 Share Posted January 9, 2012 Always good to see a happy ending.....I've kept my SWR 220 because I know it will probably outlive my tiny Euphonic Audio Micro and remain servicable for a long, long time. Quote Link to comment Share on other sites More sharing options...
