Well, it finally arrived! I was given notice that I was up for placing an order 1295 days after my initial request. I received it 19 days later for a total of 1314 days waiting! It's a V4: Boost (yellow) on the left with extra High Gain (Red) on the right. I also ordered it with the three-position toggle OD/Clean/DIST on the face so I don't have to open it every time I want to change it. It's Black and Gold - Looks really good! So what are my impressions? I just got it today so I haven't spent that much time with it yet, but my initial impressions are two-fold. First, everything works as it should and also sounds quite good. But I have to admit I'm a bit underwhelmed. I'm sure as I spend more time with it I will find all the sweet spots. I suppose with all the hype and all the waiting, my expectations were a bit unrealistic. I was expecting a super hi-fi piece of gear that would take my clean guitar signal, enhance it with space and airiness and a bit of silkiness with the boost side, and then add smooth, perfectly harmonized dirt of the finest quality and take it to the heights of distortion bliss. Or something like that. Ok, maybe that's a bit extreme but I do believe that something close to what I just described is attainable - but perhaps not with just one pedal. I guess what I did not expect was the midrange hump and added muddiness. Adjusting the tone along with some of its other features did help so it may just require more effort on my part to find something closer to what I was expecting. As I said, I haven't spent that much time with it so I'm sure I will discover many great tones as I experiment more with it. I should also mention that so far I've tried it with my Strat and CS 69's. Over the next few days I'll also check it out with my Tele's, G&L CLassic, MJT HH, Strat Pro HHH, and Duesenberg. I do like the fact that gain is not too aggressive and when I want more gain I can just add my Durham Sex Drive and/or my EP Booster. I'm sure I'll spend lots of time getting to know it better over the next days and weeks. At least the wait is over! Addendum: Please continue reading this thread as my impressions change substantially as I'm advised about the internal "Presence" feature!
