General What is your overall opinion of this product? I went from playing on a concrete reinforced to a wooden stage, and noticed that I couldn't hear myself through the bass amp. Instead of buying a more powerful amp, I bought the Gramma instead. It works!! The bass frequencies aren't absorbed by the stage any longer, and I can hear myself clearly. I recommend trying this before investing in a more powerful amp if you're using your amp to monitor your sound.

Your general opinion of this product. I could not get the tone I wanted from my Marshall combo amp at church. Then I started reading about bass amp coupling, where the sub-frequencies get absorbed by the floor in some settings like a hollow stage. Bought the GRAMMA, slipped it under my amp, and WOW! My amp sounds like it should. Stop fiddling with knobs and changing strings, your problem is not your gear, it is the floor!

Your general opinion of this product. Overall, a good product. It is decently constructed, although I find the carpeted surface a bit cheap looking.
