Dear TalkBass, First, big thank you for the ton of info regarding everything. I am still curious about one thing - if the HPF setting should be somewhere around 40 Hz (lets not discuss the number) and the preamps has the bass section somewhere around 20-40 Hz, does it make any sense to use it, meaning bass boosting? The same for the enhancers, exciters. I am just thinking if it is reasonable to use any of the bass boost if I am going to filter it by HPF anyway. And the last thing - sorry for my grammar, I am not a native speaker.
