Hi. I have read almost every thread on this subject and there is still no clear cut answer; some TB members say it's a Fender 0-10-0, others say no. I have read the article Tombowlus posted on Bass Gear and they said " Optimal Flat " was Mid-9:00, Bass- 10:30 to 11:00 and Treb- 9:30 to 10:00. When matching those settings, I get no balls at all from the amp unless I dime the volume knob; and since there is NO gain knob, that does not work for me. I then read from member RoadRanger about the " Fender 0-10-0 " where Mid is Cut only and Bass/Treble were add to taste. When using that mindset, Cutting Mid, adding Bass/Treb, this is what I ended up at : Mid- 3:00, Bass- 12:30 to 1:00 and Treb- 10:00. I now have plenty of volume and it sounds killer! Has anyone emailed Ashdown to ask them what flat is? What settings are other members using?
