Has anyone tried it yet? I have (in case you've been on pins and needles waiting to find that out). I haven't had the XL for several months (waiting for another product). In the mean time I tried three tube amps and other modelers. Well, I received the XL+ yesterday. My short review.....FANTASTIC !!!! This sounds (to me, of course) better than any previous firmware (can't remember the last one I've tried, somewhere around last summer). And, better than any other modeler or profiler I've owned or tried ( I have had them all.) I have several pedals I've kept just in case I decided to go back to tube amps for good. A pedal I bought last year, Mesa Boogie Flux Drive, always sounded bad with the amps and modelers. I almost threw it away it sounded so bad to me. Tried it with the Double Verb (Twin) model....excellent, just like I thought it was supposed to sound. My other pedals such as BB preamp, RC booster and Fulltone full drive 2 all work well. They behave like you'd expect with a tube amp. BTW, unbelievably quiet, no noise, I never touched the gate. Then I tried listening through headphones, playing that Mesa Boogie Flux Drive pedal in front of the Double Verb model. I expected a very harsh sound. The axe-fx sounded better than ever through headphones. Then I turned the dial to the Tucana model. Well, time flies... So, is this all improved because of the recent firmware updates? Or, is this because of the new XL+ LCD screen .
