D'Andrea 550 Standard Medicine Bottle
Guitar slider in the form of a medical bottle. Made of original durable glass. The size of the slider is standard.
The classic form originated from the Coricidin drug, glass bubbles from which were used as a convenient slider by many legendary bluesmen and rock musicians, for example, Dwayne Olmen of the Allman Brothers Band. Currently, the release of the drug in the original vials is discontinued, but many companies are producing glass sliders of this shape with different lengths.
