How much difference in volume / sound quality / tone / lows do you guys think there would be between a 20 watt amp (Peavey Max 110), a 75 watt amp (Line 6 Lowdown Studio 110), and a 30 watt amp (Peavey Minx)? All of them have a 10-inch speaker. I'm looking to purchase one of these, but I want to make sure that I don't spend a lot on wattage if it doesn't give me a lot more volume, since they all have the same speaker size. The Line 6 is $150, the Max 110 is $85, and I may be able to get the Minx for $100. What do you guys think? do you think the Line 6 could work for small gigs / jams? Thanks a lot!
