has anyone had any experience with these?

 

I recently got a harley benton one

I'm really amazed at the thing!

 

on a hollow wooden stage it made a huge difference in sound and tone

Living in a very old house with wooden floors, I've been using the Auralex and then the Harley Benton with great success to tame the bass end of amps a lot.

[Tjhooker]

yeah it definitely does that.

 

on a wooden stage that I have played on a number of times I noticed that I would have to cut the bass on my amp to about 10 o'clock lock from 12 o'cloc... 

 

with the harley benton mat I found I could actually boost bass and it still sounded way cleaner / clearer with much less boom

I stopped using mine because on the one stage where it should have made a vast improvement to the sound, it was negligible but it did make my bass rig wobble about alarmingly in time with the kick drum pedal.

 

@Bill Fitzmaurice should be along with the science as to why they aren't really worth it.

I have made a useful isolation platform for decoupling the acoustic noise produced by playing an electronic drum kit from the fabric of the building so my band could rehearse at my house without annoying the neighbours too much, but it was a significantly more substantial construction than a piece of plywood supported on two bits of "acoustic" foam,

I've never taken mine to a gig but I use a QSC wedge to practice at home. The old wooden floors could scratch the bottom of the wedge and they also vibrate. It's great.
