ok,I got a SWR w/m 15 say I'm playing in a medium club I will have a direct low z line out to the board,the amp has per/post gain /aural enhancer/bass control/ midrange/high control/clipping on or off/horn on or off,I would be playing a Spector NSCRFM4,theres one guitar player and the club has your normal flat club acoustics and I have no effects.this is going to be fun!
Close your eyes and play your bass. Get someone to set all the controls flat and slowly adjust each one individually until it sounds right to you. Then get someone else to play your bass and make more adjustments yourself until it sounds as good as your gear will permit. But we can't set youre amp without hearing it.
OK. Keep the bottom a bit low ... set it at about 8 o'clock. Then crank your mid to about three o'clock, and same for treble. Set your pre-amp at three o'clock, and max your volume. Bitchen.
