I'm using a Pearson 4 space shorty. Removed the rat fur (yecch
), painted it semi-gloss black, looks and works great, not too heavy and it wasn't expensive.
I like having the extra space above the amp for air circulation 'cause those amps can get quite hot when pushed. It that's an issue you can always get a one-space vent panel. Or drop in an effect, tuner, etc.
