like i said before, your heart may be set on the rectifier, but as an owner i wouldn't recommend it to a person who wants to play trash and solos...it's simply not what the amp was made for. the mark4 was definately made for that and more...my opinion only...
Consider this.........your ibanez amp is 15 watts. have you ever cranked that thing to its loudest? i have a 15 watt amp and a recto i notch down to 50w thru a 4x12. i have to put my recto louder than the 15watter to get good tones that satisfy me. if you don't crank the 15 watter to not even half, i would seriously consider another amp. if you crank the 15watter to about 8-10, you just might be able to get away with the 100watter. if you ever crank the 15watter to anything semi-loud and think it's too loud or people complain, a 100w is not suited for you at this time. i generally run my master level at around 10-1030 oclock and the bass chugs can be heard at the other side of the house. my brother comes in from playing outside complaining im too loud....so the other day i engaged the solo/output feature and ran that at 9oclock and had the master on 3ch at 12. tone was amazing, but the neighbors outside heard me standing in their front yard. this is a loud amp! volume has to be around 930-10 to get really good tones, and at this level it's really loud. i hope i'm not being too harsh here, but i'm trying to be as honest as possible. good luck!
