I've been using a Yorkville BM100 combo for a year and a bit and really want to get something better. I don't want a real rig as I don't want to cary it around and I don't really need it either. I have my eye on the electric blue 12" combo. I tried it at a store and thought it sounded awsome. The problem is, I can't tell how loud it is at the store, because I'm not playing with a crazy drummer and a loud guitar. And I definitely want something louder than my Yorkville. The Yorkville is rated 100W although they say its burst power is 115W. So, I guess the 100W is not RMS. It's Yorkville's marketing strategy. The electric blue I tried was rated 130W RMS, 260W peak. So, although I haven't had the opportunity to compare them right there, I think the ashdown should be a lot louder. So, now I'm thinking of selling my Yorkville, and a bunch of pedals and getting the electric blue. The other problem is that Ashdown's new version of the electric blue combos is 150W RMS, 300W peak, and it has a sub-harmonizer. I don't know if I would be using the sub-harmonizer a lot so I'm more attracted to the extra power. Is there a big difference between 150W RMS and 130W RMS. Would it be worth it to order the 150W one and spend $50 more or should I just get the one at the store? And how much louder than my Yorkville will I get with either one of the electric blue combos?
