Masco made small amplifiers in the 1950s. The name MASCO stands for Mark Alan Sampson Company. They were generally small amps used for guitars, PAs, and even harps. Masco has been long out of business now, and little is known about the company and what they made. Any information on Masco or Masco amplifiers can be submitted directly to Blue Book Publications.
