Why these settings

The Fender Blues Junior IV is an open-back tube guitar amp, so keep the Volume/gain low at 2 to avoid unwanted tube breakup on low frequencies. Merengue bass relies heavily on mid-range projection to cut through brass and tambora percussion, so mids are pushed to 7 while treble is rolled back to prevent high-end hiss. Keep the FAT switch disengaged to preserve a tight, articulate low end.

PRO TIPPluck with your index and middle fingers directly over the bridge pickup with firm, percussive staccato attack to nail the signature tropical tumbao bounce.
