I'm looking for some input for the GK 1001RB II amp head. I posted in another thread but it's an older post so I'm not sure what kind of feedback I may get if any. The amp has a Volume knob on the Input section and a Master on the output section. I read in the manual to set the Master at 12:00 and use the Volume to set it at a comfortable listening level. I've read some posts on here that say just the opposite. Set the Volume then use the Master to control the output volume. Can you help me out with the way the amp works? As you can see I'm not getting much with just the manual. I'd appreciate any help and maybe some examples of the settings others use. I use either a Jazz or Precision(passive)and play through one or two 410MBE cabs. Thanks for any help.
