The 301dl Dynamic Echo is one of my favourite pedals with great sound and cool options. I have two mint and boxed units in my collection.
I took the one that was in better shape and cleaned everything. It works like a charm and I gave it to my brother on his birthday in March. He loves it to pieces!
A few days ago I opened the other pedal and it was in quite bad and very dirty condition. It had a bit damage from leaking batteries that I had to remove with steel wool. The bypass switch was replaced by a different switch, thus causing trouble when turning the effect on or off. I bought the correct type and replaced it - it works perfectly now. The original rubber strips were removed for velcro. I replaced them with strips of a slip-resistant mat and they do a great job. The closing part of the battery lid is broken, but it keeps in place even without it.
Sadly I don't have a "before" picture of this pedal. In this current shape you wouldn't think that it had looked absolutely terrible before I put my hands on it. I'm very happy with the result. This one will be sold in the future.
