Fender's Bassbreaker 15 is the newest evolution of the classic Fender BassmanĀ® sound packed with powerful new features. This 15-watt amplifier delivers tonal richness and touch-sensitive dynamics for that unique Fender style. The "Structure" switch offers three distinct tonal settings for tight, "boutique"-like clean, and overdriven tones. The effects loop allows you to place outboard effects precisely in the signal chain via 1/4" preamp output and power amp input jacks.
