This has been discussed at length below. Feedback is caused by low end
exciting the body of your bass. Big amps with
lots of low end simply don't work with acoustic bass. Get educated.
Quit pushing that stone uphill.
Suggestions: Get a new rig.
A 4x10 cab has too much bottom. Try 2x10.
You can get more volume out of a smaller cab before it starts to hum.
Rockabilly bass is about the thump and not the sustain,
so you don't need a huge amp anyway. Ignore the # of watts, just go
try a few, turn them up and listen.
The Polytone 15" is highly recommended, at 100W it
makes more usable volume than that 400W
Gooberklanger or whatever it is ever could.
Also, stand as far away from your amp as you can.
Get off-axis from the speakers, ie next to or behind the amp.
Rotate your bass to the angle that hums least and keep it there.
Be sure you're using a piezo pickup.
As for playing punk rock on the acoustic... you're out in
some uncharted teritory, dude. Nobody here gonna be much help.
Try stuffing your bass with foam packing peanuts.
Cover the f-holes with duct tape to keep them from falling out.
Should solve your problem.
