I have a Gen 3 Super Midget with silver cloth grill (<10kg) and a Roqsolid bag to keep it in. Recently I walked to the railway station with the cab in its bag on one shoulder and a bass in a gigbag in the other hand - ten minutes there, another ten-fifteeen minutes walk in Milan to the shop and the return journey with a new EA iAmp Micro in the bag pocket. I would not necessarily want to make a habit of it, but it is certainly doable. It would have been unthinkable to do even part of that journey with my old (pre-Fender, > 21kg) SWR workingman's 12.
The construction quality seems first-class, I really can't fault it.
Sound-wise the cab is clear and transparent without being harsh, reproduces the low-B with confidence and without losing definition. I play a six-string fretless Manne Acustibass which can make traditional electric fretless noises as well as some more acoustic double-bass-esque tones: the cab is quite happy reproducing all these sounds (and my errors) without any sign of colouring.
I tried a number of other amps in the shop, including an impressively loud Aguilar Tone Hammer 500 and a Taurus BL 450 with very pronounced lows and highs. While these sounds were not what I was looking for, the cab was quite capable of dealing with whatever was thrown at it and I am sure would suit many different playing styles.
I have only used it at one gig and one rehearsal so far but combined with the EA micro it certainly seems to be more than loud enough for my current needs. If I do ever need more volume, I will consider adding a Super Compact.
