    My friend has a dead Fender Acoustisonic 30and I told him I would take a look at it.

    So I've taken all the bolts and screws out and loosened the chasis but it seems wired to the speaker and I don't see a way to get the chassis out to trouble shoot.

    This is an older model with the stage monitor shaped cab not the flat closed back amp style.

    I've got the chasis moving a inch or two but I'm seeing :bonkwires going to the speaker that I don't see a way to disconnect.

    Anyone ever deal with one of these POS's:omg

    disconnect the speaker wires from the speaker. You'll need to be careful to re-connect some speaker to the speaker wires after you get the chassis out of the cabinet so you don't toast the output section of the amp while you troubleshoot/repair.

    unsolder the wires at the speaker. You can then use alligator clip jumper wires (available at your local Fry's or Radio Shack or equivalent) to connect the speaker back for testing after you remove the chassis from the cab. Be *very* careful to always have the speaker hooked up properly before you turn on the amp or you can easily toast the output transistors. When you're all done and put it back together, you'll have to re-solder the wires back to the speaker (having carefully labeled the wires and speaker so you get the +/- polarity right of course <G>).

    right Psycho I've got the velcrowed Grille out and am looking at the baffle with the speaker. It feels pretty tight and unyielding, I'm not seeing any hardware. Its full of crud. This is the part I need help with

    you have to unbolt the speaker and reach in and deal with the wiring you find inside.

    I'm thinking this might not be one for you to work on.

    Ran a Mic thru in input and it was a good Vox monitor or harmonica amp the reverb is a nice touch and bottoned it up.
