Thank you for viewing. Tech 21 Boost D.L.A. - Beautiful condition. Operation confirmed. This item was kept in my collection. It has no scratches and I believe it's in very good condition. The price is a bit high because of its good condition. I apologize. This is a rare delay pedal, with a small production run. Since there's not much information available, I'll provide a little explanation. It's a Delay with added boost and modulation for a swaying effect. The tone control works well. You can adjust it from a crisp sound to a rounder one. I think it's probably a digital delay, but I believe it aims for the sound of an analog delay. I will try to ship as quickly as possible, but due to my lifestyle, it may take more than 3 days. Thank you for your understanding.
