In the 1930s, musician and inventor Paul Tutmarc of Seattle, Washington, developed the first electric bass guitar in its modern form, a fretted instrument designed to be played horizontally. The 1935 sales catalog for Tutmarc's company Audiovox featured his "Model 736 Bass Fiddle", a solid-bodied electric bass guitar with four strings, a 30+1⁄2-inch (775-millimetre) scale length, and a single pickup. Around 100 were made during this period. Audiovox also sold their "Model 236" bass amplifier.
