i own an Ashdown MAG300 head through a peavey 4*12, and to be honest... its great for electric, but i don't like it for upright... for one its way too loud, and for two, i just can't get a nice upright sound from it.
i imagine the electric blue might be better... certainly would hope so, but be careful here... Ashdown use a lot of Trace Elliot parts, which to my mind are pure and simple electric. they all seem to manipulate your sound... even when set 'flat'
i recently picked up a GK backline 112, which i like a lot more for upright (not the most popular amp... so am not recomending this outright) and this wouldn't cut an electic gig (with a loudish band) at all.
people on here like the GK MB150 and there are a lot of threrads/views about the acoustic image range and some whizzy thing.
you have loads of options outside of the Ashdown... i would shop around quite a bit... and take your time... you don't want to get something home and just get disappointed with it within a coupole of weeks.
