I got the Keeley DDR less than a week ago, now the EH Small Stone Nano. This is the biggest and most diverse pedal collection I have ever put together, but everything is simple and easy to tweak. The Boss FS-7 controls the amp. Fun stuff! Honestly all I need is the FS-7 but the rest of it is a lot of fun. Let's me do from clean to various country stuff to some very spacey sounds indeed.
