Like any bassist I LOVE to slap, and sometimes I like to put little pops and thumps into songs that I would normally play finger style. Just for a little self indulgence and basically to show off . However I have noticed that when I switch from fingers to slap, the volume of the sound coming from my amp seems to die . Because I mainly use fingers for most of our songs, the EQ is set up for a nice finger style tone, however if I know theres some slap coming up, I have to turn the amp up at least two notches just so I can hear it. This obviously isn't practical during a gig. I just bought a marshall ED The Compressor pedal to alieviate the problem but it has had little effect. I use a Trace Elliot 300SM GP7 (without built in compression), with Trace Elliot 4x10 and 1x15 and a Warwick Corvette Standard Passive 4 stringer. Can anyone offer me any suggestions which might help. Cheers.
