Why these settings

The Blues Junior IV has a naturally scooped, glassy top end, so pushing the mid control to 7 and trimming treble to 5 adds the body needed to mimic a warmer humbucker cut. Setting the amp volume/gain to 5 achieves an organic edge-of-breakup grit using the single-coil Strat when digging in. Adding an analog chorus and digital delay in the future will complete the signature lush December Avenue spatial atmosphere.

PRO TIPPosition 4 (neck+middle) on the Strat cancels hum while softening the percussive pick attack; roll the tone knob back to 8 to round off high-end spank and emulate the smooth, rounded vocal-like quality of the track.
