I bought a Gretsch Electromatic 5420 an play it with a yamaha tube amp. For effects I've got a vox Stomplab GII. Everything is fine and I am really happy with that equimpment. But! I try to get a typically rockabilly sound (like Brian Setzer). I worked several hours hard on it without any success. Sure just Brian can sound like Brian but there must be a way to find a similar sound.
My question: does anybody have an idea or a recommendation about the settings on the vox lab and the amp to get a similar Brian Setzer Sound (e.g. Stray Cat Strut)?

Greets from Germany!
