A stroh violin is a type of violin with a special amplifier attached. It looks like a regular violin, but it has an extra tube with a megaphone on the end. The megaphone helps to amplify the sound of the violin, making it much louder than a regular violin. The tube also helps to create a special kind of sound that you don’t get from a regular violin, giving the music a unique and interesting quality. Some people also say it has a bit of a ‘tinny’ sound.
