ok, after playing live with my new rig, all i can say is....UAU
the iamp 500 + wizzy is an awesome rig....i was undecided between the iamp 500 or 800, and i wrote Gary at EA, and this is what he answer me:
" The 500 paired with the Wizzy cab is an awesome setup.* It's small, lightweight, loud, and easy to transport.* The Wizzy has a warm but uncolored sound, and players that use it for upright bass have been very impressed.* Unless you need 1000 watts of power, I don't see why the 500 and the Wizzy would not do just fine."
In fact, this combination is SO LOUD, you just dont believe alll the sound which comes from this 42 pounds rig....clear, warm tone and the tone shaping possibilities are endless( i found out that so far , the sound i like the most is with almost everything set flat).
I highly recomend that if you have the chance , you should try this combination, of all the amps i had in the past(more than 20 maybe

) this is by far the best sounding amp of them all, great uncolored sound , with plenty of balls...
now, because G.A.S. seems to never stop, i want to buy a mike to use trough this rig in small places... in bigger places, i will use a pickup into the i amp and a mike into the house P.A.
i wont see myself buying another amp in a long time....
