Ditto what Graz said. Just today when I cranked up leaving the bank, an admirer in car next to me said "Wow, it sounds like a Harley". That was at idle of course but I let him hear it wind in 2nd,3rd as I went away. Had Scepters at first but too loud for me. The slash cut made the reverb off pvmt. literally give me headaches on 20 min. + rides.Love the D&Ds. Bob.
