    I have got this bassman for 200$ cuz it had alot of gigs under its belt and plenty of wear.

    Nowadyas the input jack is very touch , the sound will cut off if the cord is bumped. The amp could be cranked all the way and if the cord is bumped the amp will crackle and it will sound as if the volume is on level 1.

    So right now mycord is duct taped into it , not very classy:crying:

    i am almost certain it just needs a new input

    The question is where would i get one?

    The amp looks like this

    Thanks for any help you can provide i am in the dark:rollno:

    My GK head's input jack broke, and I called customer service. They sent me a new jack (I wanted to do it myself). Call fender. It is had as heck to find amp jacks anywhere, so I'd go to the source. Good luck!

    ............or you can order one here:

    its either a 4 pin:


    or a 9 pin:


    (they also carry a generic version of each (4 or 9 pin pcb mount) that are just as good for about 1/2 the price)


    these types of jacks aren't very rugged and don't have that long of a service life. they are very commonly used in Fender amps and there really isn't an alternative (i.e. more rugged) without modification to the pcb. with a solder-sucker and a little patience, they can be replaced fairly easily yourself.
