Just got this amp last week. Had a day or two to play around with it at the house, and then took it to a church gig tonight. I took it straight in "cold" with no time to dial it in too much. Bottom line...this amp does not sound like it is 5 watts. I was amazed at the headroom and volume coming out of this thing. I like to set the amp to break up at full guitar volume, and then work the amp with the guitar's controls from there. In my experience most smaller amps dont perform well in this way, but the Corso worked out great. Takes pedals well also. Its not something I'd use live without decent monitoring (I used a Radial JDX to get the sound to FOH), but between the Corso and speaker cab being near enough to me and a good monitor mix I had plenty of guitar for my taste. I wouldn't take it out on a straight up rock gig, or use it with my cover band, but I cant think of a better solution for my church gig. Anyways, hope you guys find this helpful. Have a great day.
