I want to give praise to the Skreddy Screw Driver and Marc the man behind Skreddy Pedals. First, I would like to thank Marc for his exceptional customer service. I purchased the Screw Driver used. The dealer that sold it to me did not inform me that the brilliance trim pot did not work properly. It could be that he did not know, but he also did not respond to my e-mails either. Not good service either way. I e-mailed Marc. He automatically said "send it back". I sent it and he fixed it free of charge. He also paid for return shipping. This was all done in one week. Ok...now that is great service. WOW! Service cannot be better than that. Now to a review of the Screw Driver. I know that it has been reviewed before, but I must concur with the others in saying that it is a great overdrive pedal. It borders on fuzz with the use of the pre gain trim pot. I think it is well suited for both lead and rhythm. It gives you subtle overdrive to a screamer with ease. I must admit that it does take time to dial it in for the exact sound. It could also be that I am always tweaking with it. I am just really enjoying the sound of it. Overall, I am impressed with the pedal and the man. Thanks for reading.
