Thanks so much Steve! I'll try the reset & frequency changes. I'm over on Dankowskis site a lot. He recommends 4H, but, it's just too much on the ears after an hour or so. I like the 2 tone option for simplicity - dig or don't dig. Just curious Steve, can u run that hot with the stock coil or with the 5"? The ONLY way my unit performs well is with the 5". I can run it to the max with that setup. Are u in the burbs or the city? Surprising the EMI doesn't hit u. Thanks again Steve!
