I thought these would be worth a shot for upright because of the selectable hi and low mid frequencies and a separate switchable graphic eq: one setting for pizz and one for arco. Well, Carvin had them on sale last weekend, so: tah dah! It came in yesterday and picked up a few last minute gigs this weekend too, so I'll get to try it in several settings. First gig last night: really loud bar gig with a 5 minute soundcheck and minimal PA support on a cramped stage. It had no problem with power running into a Markbass 2x10. I set low and high flat, with a little boost on low mid to give some muscle against the drums and small high mid cut to smooth out the pop on the attack of notes and didn't have to make any significant adjustment throughout the night. Audience comments were that it sounded clear and articulate. I didn't have any time to try the graphic for arco. Tonight: outdoor show, with a real soundcheck. Maybe I'll get more time to time to fiddle with options.
