I had to pawn off all my gear awhile ago. I recieved a Yamaha RBX170 as a gift. I was pretty grateful seeing as I was depressed not having any gear to play at all. I wasn't really happy with the sound so I put in an EMG P pickup that I had in storage that used to be on my old mexican pbass. It's wired up by itself right now. I took the stock harness out completely and theres just a hole where the 3rd knob was. It can sound pretty good for a sub 200 dollar bass but I'm not happy with the sound on the lower register (specifically the E-string) right now. It's too muddy, boomy. I have a couple soundclips (they are on soundclick, though sorry, you have to sign up to listen to it. If you know any better site I can show off mp3s I'd be very interested to hear it.) they were recorded on a small behringer mini-mixer straight into m- audio delta soundcard via cubase. http://www.soundclick.com/bands/pagemusic.cfm?bandID=381754 Anyway, ok. All I have to do is use the 25k pot for the emg's volume and the old 250k pot for the passive J pickup's volume and it will work right? I really don't want to throw money into this bass as I'm saving up to buy something nice. (bongo!) Has anyone tried this? Should I try to add in the stock J pickup with the emg? Should I just shell out and buy an EMG J pickup? Or should I just leave it alone it sounds ok? I really don't want to spend any money upgrading it but it seems to be lacking something at the moment and it may be a few months before I can get a better bass. Thank you, J.- returning to talkbass after 4 year absence.
