I'm considering ditching my Sansamp RBI in favor of a Sansamp RPM. Here's my logic: I love the sound of my RBI, but I do find that the mid control is centered too high (1k) and I always turn the presence control completely off as I find it adds WAY too much clank to my tone. The RPM would no doubt have a similar voice as the RBI, but doesn't have the presence knob (which as I mentioned previously, I keep off at all times), and it has a semi-parametric mid control that would allow me to shift the mid knob down below the 1k point set by the RBI. Does this seem like sound logic to anyone? To those of you that have used both, do you find that the RPM lacks anything that RBI delivers? Vice versa? Let me know your thoughts. Just for reference my main gig these days is a hip-hop meets funk meets blues group. I play exclusively on an alder bodied 4-string jazz bass that has a Status Graphite neck, DiMarzio Model J pickups and is always strung with either nickel/steel or steel/steel rounds. I'm playing fingerstyle and slap with this group. Thanks!
