I'm a DL4 user. I bought one when they first came out and loved it ever since. I just loved the tank like metal chassis.If you'd like to clean up the sound of your DL4. Might I suggest checking this guy out:http://www.robertkeeley.com/product.php?id=40I've sent a few pedals to him for modification and I'm happy as a pig in shiZ with what he has done. Well worth the price.
