The 1487 is one funky sound machine. Designed and built by the mad scientists at Teisco, this guitar goes Dano one better by putting the amplifier in the guitar!
This guitar could be used as a normal guitar (well... sorta...),
or you could rock out somewhat by using the internal transistorized amplifier
powered by dual 9-volt (!) batteries. This setup provided you with 1/2 watt into the 3-inch speaker.
The Teisco branded versions of these guitars had double cutaways, a slightly diffrent bridge/tailpiece, and bore the model numbers TRG-1 and TRE-100.
