Fantastic little National (by Valco) 1210 5w guitar amp. The G2xxxx serial number dates it to 1964 according to this site.I understand it has the exact same circuit as the Supro 1606. Goes from blindingly sparkling cleans to filthy distortion at reasonable levels. Hard to imagine you'll find a nicer one that this!
