Hi guys,

looks a bit bigger than the 'Nano' but sounds a bit better, price not bad either

the Rock Block sounds better than the Zvex, but then again, thats to be expected with the valves used.

I've made something similar before - you can get some great results, but its still loud in the bedroom.
