So I like the tone of my GK 700rb, and the EQ points on it are very musical. However, to get the sound in my head I need to boost the low mid frequency that is in-between the Bass and Low-Mid EQ points on the GK. My friend and I were talking about the MXR Bass Preamp today and how it had a sweepable mid knob. Would it be good for accentuating that mid frequency without coloring my tone too much? I also understand it would just help beef up the signal in general, and it would give me the options of DI and broadened tone shaping. OR is some type of graphic EQ more along the lines of what I'm looking for?
