For sale at Sonic Circus is a vintage Silvertone Guitar in an Amp Case serial #185-11090. These guitar/amp sets were originally sold by Sears for a limited time only. This combo is a gem! Originally from the renowned Indigo Ranch Recording studios, this guitar and amp case are fully functional. It is marked Indigo in a number of places. We had a blast playing with this little guy in the shop. It is getting harder and harder to find these things, especially in the shape that this one is in. This combo does not include a guitar cable.
