Hi, it's Andy with ProGuitarShop and ToneReport.com and we’re getting a look at the Sub ‘n’ Up, by TC Electronic. The Sub ‘n’ Up is a compact, highly-versatile octave machine with some serious low-end. True to its name, the Sub ‘n’ Up gives you access to mix controls for one and two octaves down, as well as one octave up and a master mix control for the dry signal. Turning the Dry control all the way down will eliminate the original guitar signal from the output, turning any guitar into a stage-leveling wall of bass. TC’s next-generation octave engine makes the Sub ‘n’ Up track 100 percent flawlessly, if you want it to. Three modes are available in the Sub ‘n’ up; in Poly mode, the pedal tracks like a champ and will rattle every window in your practice space with its gut-punching lows and crystalline upper octave tones. However, in Classic mode, the pedal changes to an old school monophonic octaver that feels authentically old school, complete with slightly off-kilter tracking that will glitch out when you feed it complex chords. The Sub ‘n’ Up comes equipped with TC’s groundbreaking TonePrint technology. Using the TonePrint app or Editor, you can tap into TC’s library of artist-created patches which include various types of modulation. The stock TonePrint on the Sub ‘n’ Up adds a little warble to the octaves for a superb organ simulator. And just like all TC pedals, the Sub ‘n’ Up comes in a durable housing and is wired for true bypass.
