Make C1, C2 and C7 higher in value for more low end.
Play around with the value of the feedback cap C4 to tailor the mids/highs.

You can also slightly change the value of R9 to tailor the response. It mostly enhances low/mids but affects the gain of the whole circuit.
R10 controls the compression.
