hello, I have a micro korg synth that i am using for some bass lines on some songs i have. I run it through a carvin ps418. some one told me that I should be using a high pass filter or some type of crossover or somthing like that, so i dont damage my speakers. does anyone have any recomondations for signal processing when using a synth through a bass guitar amp, I really want to use the synth through my bass amp and hit some really low notes but i really dont want to damage my speakers or amp. any help would be greatly appriciated. Thank you!
