Mesa D800 rattles off cabinet to oblivion

[modalsum]

well not full oblivion. but almost.

i love my d800 w/ my 2 1x12'' cabs. but i'm two gigs in now with it and literally had to keep an eye on the head as it kept vibrating off my cabinet. a few times i'd have to go midsong in between lines and push it back from the edge. and this is w/ the bass around 1 o'clock, master around 11 o'clock and input at 11 o'clock.

thankfully i had PA support each time, but if i had to push the headroom up in a situation w/o PA i'm afraid the head would fall off really quick

i can't be the only person this is happening to and am thinking a rack is probably the only way to suffice - which kind of defeats the handiness of a small head in a shoulder bag. but wondering if anyone else has any crafty solutions?

I use a bar mat I bought off Amazon. Something like this: https://www.amazon.com/Durable-Styl...jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

Non-skid mats like tool drawer liners work well. There have been several threads about this, non-Subway specific, will help the search.

This is an industry wide issue due to the increased output of the cabinets combined with the lighter weight amps.

I have a sheet of drawer liner under my D800+ and it doesn’t move.

I use this large mouse pad, perfect size for the D800+. https://www.amazon.com/gp/product/B01ANHH82M/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1

Problem solved!

Disagree. The head is walking off the cab because of excessive vibration. The cabs need more bracing front to back and side to side.

I have my homebrew 2x15 and a Fearful 12/6 plus sub cab, and the heads do not move. At all.

One guy in a Phil Jones Bass thread set metal cups into the top of one his powered cabinets for his head so the amp feet fit into them. Problem solved.

the responses on this thread are literally why this forum is awesome. thank you all.

You could set a Fender PS400 on top of the Mesa to hold it down.

Haha, yea I imagine this happens to everyone. I play primarily reggae and my focus is sub lows. I honestly just put on some some rubber 3M feet and it’s been rock solid, hasn’t budged.

Decades ago, I first had the problem with a dual showman head I didn't screw down tight enough. Same with a Bassman (on their original cabinets). I just put the heads on the floor, figured the tubes didn't need the vibration, anyway. Sounds like the drawer mats are a good way to go for these light weight amps.

If you set your beer on top of the head, that’ll weight it down and fix all potential issues, for all time.

Head does not try to jump off my 2x15. With the 1x15, I just set the head on the folded up slip cover. Problem solved.

I have to agree with this ... if the cabs are vibrating so madly that the amp drops off the cab, then something is kind of wrong with the cabs ... and it's likely that inadequate bracing is the culprit. I have used my WD800 on hundreds of gigs in the past few years .. generally on top of one or another of my Berg cabs and I've never had an issue. I can even put drinks (however bad an idea that may be) on my rig and they never vibrate off.

Cab vibration issues caused me to operate on a 70's era Fender Fullerton EVM 15 loaded cab. I ended up bracing it front to back, side to side and top to bottom, and it really reduced the overall vibration issue.

No clue what the problem is. I have my D-800 cabled to 2 1x15 cabs. I have had that cranked during outdoor gigs. Stupid loud.
Volume past noon.

The head never moved. Never had an issue.
