Wren and Cuff J. Mascis Garbage Face Jr. Fuzz Pedal A bonafide guitar legend by any standard, J. Mascis and his band Dinosaur Jr. toured with and influenced many of the bands that defined the 90’s -- bands like Nirvana, Sonic Youth, Mudhoney, and too many others to count. Ask nearly any punk or grunge band from that era (and of today) if they’ve heard of J Mascis, and you’ll get a look like you’re a fool for even having to ask.
