I am fairly new to the world of pedals and would like some tips on setting the parameters where there are similar controls for tone and volume. My current pedal board from guitar to amp consists of a Keeley Compressor Plus, EHx East River Drive OD, a Machine Head 72 Degree OD, and a Caitlinbread Topanga reverb. For now, the Machine Head is being used as a boost only option with the EHx supplying OD. The Keeley is the newest and I'm still experimenting and learning what it can do. I play mostly at home through blackface amps (Vibro Champ & Vibrolux Reverb). Music is primarily blues and 50s-70s rock. All four pedals have both tone and volume controls and I'm not quite sure where to set them. I'm especially unsure about the tone controls. Is there a neutral position. I apologize for a somewhat unarticulated description and appreciate any advice that may help me to get the most from the pedals.
