I have an old Roland cube 60 bass amp and a preamp i want to fix to put in it. I have checked the speaker and it is fine. While in use, the volumes fades and jumps up and down. When being played in lighter songs, the quality goes straight downhill. At times it sounds brand new but then at other times it sounds like theres a rip through the speaker. Can anyone help me with anything that I really need to check or what it could possibly be? Im hopin to be able to rebuild it without having to buy a new one.
