AMPLIFIER BLOCKS

Get a real stand look at Symposium Ultra it will improve your sound very much.Or get Blocks whatever that is which will give little sound improvement.Good luck!!

Procure some thick maple butcher block and some brass cones. Spike wood to floor and sit amp on cones. It will improve focus and sweeten the sound and even if the effect is minimal, it will look good.

Everything you do will make the sound different.  I use Audio Points, but have used Cardas Blocks, et al.  Try the little cans of tomato paste in their side...point them in different directions to prevent the amp from rolling around....(this is serious...you might like the sound of the cans the best....brings out the spaciousness and air around the instruments)
