Im looking to spend up to 500$ for a combo amp that i can play at home but yet take it to small gigs. Im tired of hauling heavy cabs and heads. 1. How many watts will do? 2. What style of speaker is best to get good volume and punch. 15in/12in/2x10/2x8? 3. Trusted name brands? Any one played an eden N28? cant find anything anywhere. Love the simpleness of it.
