Why these settings

The Spark 40's 'Black Duo' model provides the clean Fender platform needed for this track without requiring external pedals. We push the midrange to 6 and roll treble back to 4 to replicate the warm, lo-fi offset pickup response on your brighter Pacifica single-coil neck pickup. The onboard compressor adds the characteristic taped-down dynamic squish of Alex G's home-recorded acoustic-electric blend.

PRO TIPPick lightly with the fleshy part of your thumb and index finger rather than a hard pick to soften the attack and capture the intimate, bedroom-pop feel of the recording.
