I have opportunity to pick up a Nemesis NC-410P combo for around $500 or so. Problem is, it is in another state and no one around here has one that I can try to see if I like the sound. I am looking for a small/medium sied unit for clubs and small gigs. I mostly play fingerstyle with my Cirrus 4-stringer and a Carvin LB20 fretless 4 stringer. My questions are: 1. How would you characterize the sound of this amp? 2. Can I hook up an external cab and get a little more than 225W? 3. Is $500 an ok price for an amp of this type? Thank you in advance!
