I currently own a Peavey TNT 130 from the early 80's with a 15" speaker. I am looking to get a newer amp because this one doesn't seem to have the power or tone as some of the newer amps with the same wattage. I am looking into either getting a combo with 2 10" or a newer 15" combo. We mainly play outdoor gigs at parties and such with anywhere from 100 to 300 people. Any suggestions are welcome.
