Your circuit has an input impedance roughly equal to the value of R3 which I suspect is somewhat lower than R4 probably by a factor of 10. Even at 150k it would be too low. A better approach would be to use a non-inverting configuration for the op-amp such as. Web5. Guitar pre-amps are usually designed with a high input resistance (typically 1M0).
