Yeah, swapping resistors and shaping the driver curve is classic. The sweet spot’s usually when the gain stays linear enough that you don’t clip on the transients, but still gives you that natural roll‑off. Start with the op‑amp’s internal bias: keep the quiescent current low enough to avoid bias drift, then tweak the feedback resistor for the exact gain you want. If you’re aiming for that pristine mid‑range, try a slightly higher series resistor to roll off the high‑frequency hiss, but don’t over‑compensate or you’ll lose those crisp sibilants. Once you hit a good point, lock the values and run a quick frequency sweep—listen for any hum or distortion that pops up when you crank the volume. If all’s clean, you’ve found your sweet spot.
