The product is great, the price was fair market price and the company shipped the product right away. FedEx dropped the ball and from what I was told by FedEx, the package sat in a holding center for 4 days therefore missing the expected arrival date. Makes it difficult to time scheduling to be home to receive my fairly expensive package. (There have been a lot of thefts in the neighborhood). But having said that, I got the unit and it is great. I like the overall sound quality of the Zoom B3 much better, (and especially... the wah effects and the choruses in the B3 were much more pronounced, warm and versatile..) but this unit does so much more the tradeoff is worth it. The looper section is absolutely awesome. If you play to a drum loop, it quantizes the end of the clip to make sure it aligns with the guide loop. Nice!! The fact that I can A/B between my electric and my Kydd upright is great. That alone is why I had to get the unit. What I had to go through before was a pain. Yo!!! The Tuner is THE BOMB!! Great big, stage visible, locking Tuner!! The touchscreen and the versatility of the editing of effects and effects chains is awesome...being able to move slots around with just a swipe makes it easy to see how one effect affects the next and you can tweak the sounds to your particular instrument. I have patches customized & tweaked for my Hi Tech BassMods bass, for my FrankenBerry bass which is heavier and darker sounding, for my old Yamaha Fretless.. It's great. The various modes are also great. I basically use pedalboard mode for live and if I feel creative, i might use a patch here and there depending on the gig...but mostly I have dedicated pedals I use over and over in different sets of patches. 4 pedals at a time. Makes it easy to navigate during the gig. The unit looks just beautiful. Streamlined, Graphite looking. Colorful on the dark stage floor. Zoom & Carlitos Del Puerto did a fantastic job in the design of this unit. I hope they do a firmware update that brings the sound level up to match the B3 and incorporates some of its algorithms. There are some effects in the B3 I just cannot duplicate in the B6 (no matter how much I tweak), that I will surely miss. I relyed on some of those sounds. My name is André Berry. I play bass for David Sanborn, The Brothers Johnson, Eric Marienthal, Chris Standring, The Jazz Junkies, Agape Spiritual Center and Nikki Harris. Over the years I have played for Dave Koz, Warren Hill, Wayman Tisdale, Rick Braun, Peter White, Jeff Golub, Kirk Whalum and for The Smooth Jazz Cruise. If you are a bassist, the B6 will up your game for sure. It's a pro's tool with a lot of useful practicality and its a ton of fun! Great job Carlitos! Right on Zoom. Peace & Blessings.
