vintage 1970s Peavey Electronics Musician 300 guitar head amplifier

These earlier - mid '70s Peavey amplifiers are sort of diamonds in the rough; capable of tone and musicality in ranges that just cannot be produced by other popular amp designs. This is a Series 300 Musician head for electric guitar (or keyboard) - sounds great, works well except for the phaser function - that doesn't work; perhaps it uses an optical or bulb component like other modulation effects have been known to. I have not inspected the phaser circuit internally nor had it serviced. Only light wear and tear throughout on this amp. USA made, early Peavey with the metal serial badge on the base. Like what you see? Buy it fast, these heads are growing in demand daily! thank you for looking!
