I have an Ampeg B1RE Had my first gig with my band last week,got to sound check and head wouldnt work.Horrible smell on stage and just gave up on it Got back home and had look inside and no sign of burning/smell inside.DI was still working as tried it out with my multi track I realise i will need to get it seen to but would like some thoughts on it so I know what I need looked at as I just had it seen to not long ago. Any help greatly appreciated

I was wandering if anyone had any links to people (preferably in the uk) who make their own pedals. Any effect type cheers
