Just got my Mini-Recto today! Excited to plug'er in and let'er rip! I sold my TA-15 to a colleague of mine to fund it. As much as I liked the TA-15, there are aspects of the Mini-Recto that are more suited to my taste. I like the addition of the Mid Knob, Presence Knob, and Loop, all of which were things I missed on the TA. Next thing is a loop pedal that will bypass the loop and change the channel (will also work with my Mark IIB).
