The Fender Concert II is a post-CBS-era combo from the early 1980s, delivering 60 watts through two 6L6GC output tubes with a dual-channel layout featuring clean and drive channels. It represents Fender's attempt to modernise and re-establish its product line following the transition out of full CBS control. The Concert II is a capable, versatile amplifier that captures the spirit of Fender clean tone with more gain options than the vintage models.
