perfect for what i need. as is very often the case with guitarist such as myself, i find myself chopping and changing me effects VERY often. sometimes i will be very happy with a particular et of sounds or equipment, but next night, i will decide i need to change things. it can be avery complicated business indeed to use some of the modern type of multi effects units indeed. i have used most of the big brands over the years, with varying levels of success i must add. i then decided that i would go OLD SCHOOL ,and return to single pedals in front of me for all of my live work at least, if not recording also. i then found to my cost, that batteries do NOT last very long at all,and are also VERY expensive to use in the long term. so i bought a power supply,and set of these most EXCELLENT daisy chain leads,and i am still using them today, many years later;-) success!
