    I have this 2005 Fender Pro Junior that is labeled "Custom built for Australia". Cant seem to find any info on it, I believe it was a matching set from a Custom Shop Guitar and amp package but not 100 percent sure. Solid Pine Cabinet with a Jensen Speaker, Sounds absolutely amazing, but is quite noisy even at low volumes. Any info on the amp.

    Our Voltage is 240V downunder, maybe the transformer is different?...... is there a code number on that to compare with a US one?...

    all I can think of.... unless it's got upside down electrics?... ;)

    Try removing the top center screw on the back panel and see if the hum is reduced. Works for some.

    You can also play with the ribbon cables, mainly reorienting them to see if hum changes. In your pic, make the ribbons on the right look more like the ribbons on the left.

    You could also clip the zip ties on the wires and reorient the OT wires.

    The latter two require you to tweak with the amp on, so be careful with your fingertips.

    Is that data plate rusty?
    Maybe the amp was damp.
    Clean the tube sockets?

    I'm always afraid of that kind of stuff, don't want to get shocked

    As a partial DIY discharge

    play the amp, hit a big power chord and unplug the amp while switch is on

    Open up the back and summary: make the wires look like in the photo

    careful not to touch anything else:

    -snip tie wraps holding those green or red or black white wires coming off the transformer

    - find the middle of the green pair and twist them so they're twisted, tuck them as in photo
    (twisted...less hiss)

    - use new small tie wraps to get the green wires and red wires to cross each other at 90 degrees
    - same for greens and black/white pair
    (wires crossing at 90 degree angles...less noise)

    You can see I'm kind of achieving that in the photo

    Thats it for lead "dress", maybe better 12AX7 tubes after that to reduce hiss

    DON'T touch anything else on that green board

    2006, not 2005. Looks like some sort of 60th Anniversary commemorative edition (see the little medallion on the back plate with "60" on it? The Woody models from that year have the same medallion.

    I posted this in another thread. I've had several BJ's and Pro Juniors and they ALL made weird noises. I just picked up a pro junior III cheap, not very old at all, and it's so "hissy" that it's unusable (didn't play it first, my fault). It's sitting in the back of a closet somewhere. I'm trying my best to like them but I'm about to give up. Cut the tywrap and move around the wires, flatten out the ribbon cables, lower the bias and see if that helps. I could never get them quiet enough for me.

    That top center screw removal helped mine.
