Hi all, I'm playing my upright w/ a full circle pickup, and going through my 450 watt Ampeg head and 300 W Harke cabinet, with no preamp- the same setup I use with an electric bass. I've heard really good things about preamps, but have not been sure I've needed one.. yet I can't get my sound to cut through (even w/ the treble up). I end up just turning up the volume, which can overpower the other instruments.. Would including a preamp help the tone/sound presence significantly? I play with low tension strings and am really looking for that rockabilly click/slap sound, or just more natural sounds of the strings and bass. Any other recommendations on how to get the bass' natural sounds more audible and out in front (so I don't have to crank it) would be appreciated! Thanks!!!
