Thanks[/quote] It would depend on the type of distortion you are refering to - and would be difficult to tell, without hearing it. My first thoughts that you are hitting the natural resonance of something. Have you tried a different bass in to your amp and cab? Could you also plug your bass directly in to the 'return' of the effects loop and play to see if you get the distortion there too? Then we can start to see what *could* be causing the problem. I think the EVO has a preamp valve? for example - that could be loose / in need of replacement - but it could be so many other things!

Dood Posted September 10, 2010 Share Posted September 10, 2010 Oh, if you can get a clear recording of the distortion, by miking up the cab - we can have a listen! Quote Link to comment Share on other sites More sharing options...
Dudgeman Posted September 10, 2010 Author Share Posted September 10, 2010 I'll try the effects return trick..hadn't thought of that. Yes it does have valve preamp and so that could be a problem.I will try and post the sound next week as I am away this weekend. The distortion is soft and fluffy sound almost like a bass version of a Kazoo !! it is not harsh or gritty in any way..dont know if that helps!

umph Posted September 10, 2010 Share Posted September 10, 2010 how old is the ashdown? I really doubt this is a valve problem. It could be a power supply problem. Quote Link to comment Share on other sites More sharing options...
ZMech Posted September 10, 2010 Share Posted September 10, 2010 could it be something in the room you're playing? Quote Link to comment Share on other sites More sharing options...
