...or something similar? Here's a link: http://www.clearsonic.com/a2-4_amp_shield.html I went to Home Depot and bought some Lexan sheets and built myself a shield as an experiment. It actually worked quite well, from the building standpoint, but in my first trial it really changed the tone of the cab, in addition to doing what I had in mind. I had it in a room in my house, in front of a 1x12 with nothing behind the cab, (just the wall). It really gave the amp a kind of nasal tone that really sucked. I assume it's the reflection off the wall behind the amp and I wonder if the "Sorber" panels are required behind the amp to stop this effect, or if it's just something that you have to live with to use this type of device....or is it my choice of material? Any insight?
