AER Tilt System

I bought this to see if it would work with my Markbass CMD121P - and it does the job perfectly well at a very reasonable price, pointing the bass at my face and not my feet and reducing direct contact with the floor - and it's foldable and slips right into the hollow at the back of the amp - or wherever. Admittedly, the combo isn't that heavy (just over 13 kg/29 lbs.), but I imagine it would take weightier things fine.

The wedge would seem to go well, then, with combos that are short and squat. I could see it working with squarish guitar amps too, but not with tall ones, like Fender Hotrods - or anything that is much taller than it is deep - gravity dictates that they would just fall over. I tried it with my Blues Deluxe - and it doesn't work - I also tried with Twin Reverb, and while it balanced without falling over, it just looked too much on the precarious side. But cube-type amps should work just fine.

So in my case and with its intended use for a squat combo, it definitely does the trick.

Not just for AER amps!
I always wondered why many floor wedges aim the sound at performers knees... The AER tilt allows you to tilt the monitor up, so it's pointing directly at you. This means you can have it quieter, which is better for everyone...
It folds flat when not in use so it should slip into the monitor bag easy enough. We also use these under bass and guitar amps, to tilt them back a little (make sure they're not going to fall backwards!) so you're not just using your legs to hear your tone. Very hardwearing, you'll wonder how you ever managed without one.
