Nice pedal! A little tube screamerish, as far the drive and how much drive. Definitely not as over the top rock'n that I heard on their site with Alan Hinds so that was a dissappointment. The Tone controls are nice, cut or boost feature and the volume level gives a nice boost! Has anyone else been surprised that the BB pre amps drive cranked and the volume at unity doesn't that much drive than the zendrive ( though voiced differently- as the zendrive's highs are more smoothed out).????
