    Hi there. Long time lurker, first time poster.

    I came into possession of a Peavey Firebass amp head. I have a problem though... When i plug my bass into the input jack there isn't a peep coming from the speakers, when i plug into the EFX return jack i get a regular bass sound.

    I've checked leads, fuses etc... all seem fine. Does anybody have an idea what the problem might be?

    You have a problem with the pre-amp section of your amp. Try linking the Effects send and return with an instrument cable and see what happens. If the amp now works as it should the "normalizing" contacts need to be cleaned.

    If not and the amp has a tube in the pre-amp try changing it.

    Also, It could just be a bad input jack. I would take the lid off and have a look around.

    Great advice - IF the OP knows what he is looking at!
