howdy all, ive bought myself an amp from ebay.. its a 100 watt FAL KESTREL combo guitar amp. the amp itself works great!! Except, its got two holes where there were two buttons i pressume for ''Brightness''. those buttons have fallen behind the head. any suggestions on how i can fix it? or what i'm supposed to do? any tutorial website link etc etc?..i googled fal kestrel without any results. it would be great if i can fix it myself i dont fancy taking it to the guitar shop. thanx!
