Mine is BFG modded. I bought it new and had it sent directly to Brian.......so I have never heard one stock. However, it does a spectacular job at modern metal IMO. I had some initial problems, but Brian sorted it out quickly. I have since sold off my EVH 50watter because I prefer the JCA50. The loop is a bit sketchy, but it works well with the MXR Carbon Copy........but most pedals not so much.
