I have a barely used BOSS Katana Artist MkI 100W 1x12 Waza Craft amp. Everything works perfectly, firmware and software are fully updated to latest versions. I purchased with no gigging in mind, solely for jamming at home. This amp WILL gig fully, it's an absolute powerhouse. The only reason I am selling is because my family pitched in and surprised me with an upgraded brand new amp and I don't want this beast sitting around collecting dust. It has been sitting in my closet and I hate to see it go to waste. The Waza speaker I itself is amazing and putting it a 0.5w for just playing around at the house has been awesome. I can swap it to the full 100 and play at live Nation if I wanted which is the beauty of this amp and it's crystal clear. I want it to go to a good home, it's been loved and everything I wanted in an amp. It's has very little cosmetic blemishes that I just haven't cleaned up but it has not been abused at all. I take care of all of my rigs. If you have any questions or need/want more pictures or anything please let me know, thank you!
