I am moving on from my practice amp to a new rig. Ive never played out, so I dont know much about how much power is needed and whatnot. However, from doing some research here Ive come down to this... I am currently playing rock music and ive noticed that 500 watts seems to be enough to get by at decent sized venues. I am thinking of getting a 210 @ 8 ohms for now. Eventually I will add another 210 or a 115. I have $500 to spend on this rig. Id appreciate recommendations on a 210 and 500watt head for around that price.
