The Fender Vibrolux AB763 is a 35W blackface combo with two 10" speakers, spring reverb, and vibrato, occupying a sweet spot between the smaller Deluxe and the louder Super Reverb. Its 6L6 power section gives it more headroom and a slightly tighter low-end response than the 6V6-powered Deluxe, while the 2×10" cabinet produces a distinctive open-back chime. A versatile and underrated member of the blackface family.
