I'm using this with my Taylor GS mini since almost a year. I found it very good as every time I used to play my acoustic it used to sound dry... So at a live gig this made my guitar become more warm and soothing, eliminating electric dry feel. This pedal is helpful in that sense rather then playing much more effects. Also you can use it for your electric guitar, so no worries to carry two processors of you don't require much from your electric... Battery operation doesn't work that long as told, hardly might work for an hour or so (with new batteries).
