i am looking for a smaller amp as the set up i have is way to big. ive looked at the hartke kick back 12 and enjoys the sound but is 120 watts going to be loud enough? i play with fairly big 10-14 piece bands. totally acoustic. and smaller jazz trios etc. i need a small ish amp preferably a combo and for under £400 great britsh pounds. i couldnt find anything specific to what i wanted to know. thanks for any help. the reviews for the hartke seem good but problems with how loud it is. many thanks.
