Is there anything else I should consider before I buy? IMO the DL4 is a most interesting delay and a great *vanilla* looper. In other words the looping is pretty straightforward and simple without a lot of extra things in it. There is a short delay insdie the looper which can add some effect but otherwise it's a simple loop, reverse, 1/2 speed machine all easily available in realtime with nice big stomps switches. I looked at the newer boss loopers and if I'm not mistaken you can't reverse on the fly without a third extrenal pedal. Don't know what other features they offer. The real question you need ot ask is do you want a simple loop box or do you want something to mess up the sound on the fly inside the box once it's there. For me, there is no better *simple* and convenient loops box than the DL4. it's entirely self contained and a battery run floor unit so you don't need *anything* lese to loop. plus it's got some crazy delays in there as well so you can use it for many, MANY other things outside of looping. ___________________________________________________________________ HELP WANTED PRODUCTIONS - Http://www.HelpWantedProductions.com "Bringing you the best in Organic Electronic music since we started..."
