Boss pedal quality is always top notch in terms of build quality and tone. The dd7 is not different. It would take quite a bit of time to explore all of the features in the pedal but my main need was for that traditional transition to delay when playing the lead guitar. I am very satisfied with the pedal. The hold option is nice to have though am not sure how useful it would be. Am very traditional when it come to playing so am not bothered about lots of fancy features. Am more interested in the tone quality and I am very happy with the pedal.
