Head keeps rolling off my cab?

[creis2]

I know I should have taken a welding class .

[creis2]

So I finally got a video up. I made it short, my poor dog hates noise.

My SVT isn't here, but I used an Ashdown Klystron instead. Although not as heavy, the Ashdown weighs over 50 pounds, not exactly a lightweight.

Anyway, you can see the knobs are pretty flat and volume isn't very loud. In the video it sounds loud and distorted, that's just my phone. The volume was pretty low for gig standards and was clean, with no effects and played through a passive bass. My phone does make a great overdrive pedal huh?

The visual also kind of stinks, but you can see the head shift back. The video is also shaky because I'm trying to pluck the string, hold the fret and hold my phone at the same time.

I have an old peavy head I don't use much. I should take a high quality video of that falling off the cab with me rocking out in front of it, that would make a sick gif.

That's entertainment right there! All 10 seconds of it. Not even loud, away it goes!

I'm thinking the cab probably buzzes with amp on the floor? Loose brace or no brace. Easy fix.

No, that's dumb abuse of a good amp.

I've tried all sorts of stuff. Casters on and casters off the cab. Different size rubber feet. Playing on hardwood and thick carpet.

Not that I would do it, just trying to fit in with the TB club and be cool. 2nd grade all over again

You know what a brace is and what it does right?

Yeah, I've had don build me many cabs using 1/2" ply, so it's been explained to me many times.

I popped one of the drivers out and shook all of the braces, everything seems to be snug.

It won't fix the underlying problem, but in the meantime an air bladder of some sort would isolate the amp from the vibrations. I'm thinking patially filled inner tube, or maybe a couple layers of the big bubble bubble wrap.

MMMmmm..I was told decades ago by thea warranty repair tech, to NEVER place my Acoustic 370 head ontop of a cabinet...and it is Solid State.

Same would hold true for any powerful head; especially a tube head. Bass cabs cause severe vibrations....PERIOD.

I use a restaurant folding stand; the kind they use to bring lots of plates to your table.

I know.. it doesn't look AWESOME, but I worry less.

No they should never vibrate there own panels! They are supposed to couple the speaker to the surrounding area, not waste the conversion on rattling their own panels
Decades ago cheap built cabs were the norm. Now we have come to expect and demand higher quality.

I just can,t resist! Play a Db instead.

Got pics of the inside of the cab?

8 pages later: great question

[mournblade]

Could cheerleaders be the new carrot?

Hahaha

[creis2]

Thread derailed. Adios.

[seamonkey]

Here's the best way to brace


Your fix could be as simple as running a single brace from the top to the bottom, but I expect it needs more overall.

A woodworking can stab one in pretty quick.
