This mando was made during the esteemed “lawsuit” era where high-quality Japanese and Korean manufacturers were blatantly copying famous instrument designs verbatim. This short-lived period, confined within the 1970s, spawned a dense amount of affordable musical instruments which have since become quite popular, noted for their advanced craftsmanship, during a time where even US-made instruments were becoming sloppy.
