First Vintage Reissue Amplifier
In 1987, THD Electronics put the first vintage reissue vacuum tube guitar amplifier into production, the 4-10 amp. It was modeled after a 1959 5F6-A "tweed" (a misnomer: the cloth is actually twill) Fender Bassman and, unlike the Peavey Classic Amplifiers of the 1970s (which were covered in twill-patterned vinyl) the 4-10 was covered in authentic cotton twill, the first since Fender and Gibson stopped production of twill-covered amplifiers in 1960. The 4-10 was in production from 1987-1993. In 1989 a head-only and 2-10 version were released as well.
