Never have I heard tone or just outright over sound quality like this in an amp with something smaller than a 12" speaker. All the practice amps I've tried over the years have sounded like tin cans to me. I have played 2X12 combos that were not nearly as full sounding. It's deep pool and just awesome. But the optional app for PC editor takes this amp from being great to downright amazing. Using the app via my Android my cell phone allows me to edit all the parameters I can control the treble middle and bass frequencies independently all of the parameters for the effects like modulation depth, rate, speed high cut low-cut level, a variety of Reverb types all of the parameters of the Reverb and delays. Including access to two different types of compressors A Noise Gate and a variety of cab emulation. I would actually put this amplifier in the top 5 sounding amplifiers I've purchased in over 35 years of playing, right up there with vintage Marshalls, Mesa Boogie, Matchless this thing is that good and that impressive. And to top it off it's completely portable runs on batteries even I was absolutely floored and Amazed by this amplifier. If you're even remotely hesitant don't be it's a fantastic sounding amp a great investment just all-around fun to use, I would even be more than willing to use this at live shows and mic it, I would be perfectly happy and content with his amplifier if I had to get rid of my main amps I could be just fine with this one.
