so i have a yamaha rbx 250 and im looking to upgrade my sound in some way. the bass by itself, you can only basically get two sounds out of it. tone all the way left yo get the warm extra bassy tone. tone all the way right and you get the brighter tone. cant really get a nice pop or crunch with the tone al lthe way up and im looking to upgrade this setup slightly just to keep things interesting and fun while i am learning the bass. i was thinking of either upgrading the pickups to some active p bass style emg pickups, or picking up some kind of pedal that will boost or drive that passive signal, something like the mxr m80 or an eq pedal or something. i'm using a cheap acoustic b100, 100 watt amp.any suggestions or comments would very much appreciated. even if its just to point out that im a noob and steer me in the right direction itll go a long way. thanks!
