As a cabinet builder, I use the Elf for test and demo purposes. My pro bassist friend has gigged with it and is not totally happy with the tone.
Pros: Compact, great looks, simple controls, price
Cons: Limited tonal range, runs hot, weighs approx. 900 g instead of stated 730 g.
There's many micro bass heads out there and I would seriously look at GK MB 200 (which I also have) in this bantamweight category.
