I must admit from the get go, I know nothing about pedals. I have spent the last 30+ years working on the tone of my bass, speakers, cables, amps and strings. I would like to add that next dimension to my sound - Pedals. However, I do not want to disrupt the tone I get with my set up. I want effects to be just that. How do you all get your tone Bass-Amp-Speakers to stay that way and add in your pedals? Are there pedals that drop your output? What do you do with that? Are there pedals that increase your output? I mean, if I add an effect, I do not want my volume to change in any way. How can I accomplish that? I play a Modulus Quantum (9v Active), SWR Bass 750, Schroeder Speakers and George L's cables. I am just really confused.
