The Sundown Rebel 50 (SDR100H) is a guitar amplifier head from Sundown's lineup, suggesting a 50-watt or 100-watt switchable design aimed at gigging guitarists. The 'Rebel' name implies a harder-edged voicing compared to the brand's cleaner offerings. Sundown amplifiers from this era were budget-to-mid-range alternatives to more established US brands.
