This rig has a significant impedance mismatch between the Ibanez TS9 and the EHX Big Muff. The TS9 is designed to work best with a higher impedance input, while the Big Muff prefers a lower impedance signal. Essentially, you're losing dynamics and clarity due to the TS9's buffering before hitting the Muff. A better approach would be to place the Big Muff before the TS9, allowing the Muff's more saturated signal to be shaped rather than choked by the TS9's output.
