Small black box; big bass sound. That's what you get from the baby of the family, the Rumble 15 bass combo amplifier, covered in tough black vinyl and ready to shake the walls with 15 watts of strong, clear Fender® bass sound through an 8" Fender Special Design Speaker. Delta Comp adaptive compression circuitry keeps your tone tight and in the pocket, with a 3-band EQ for fine-tuning your overall sound. Tools like an aux. input for your CD/MP3 player and a headphone jack make your practices more fun and productive. It's all wrapped in a tough, textured vinyl covering with a rugged black metal grille on its face.
