I have a gt-6b that I would like to use as a preamp. I play contemporary gospel mainly. I want to use the gt-6b directly to a power amp (Samson SX-1200). However, I don't like the sound or level that I am getting. Does anyone have any suggestions on what settings I should use. By the way I play finger style 60-70%, 30-40% slap thanks for the info.
