The different flavors of one of the most iconic Guitar pedal: The BOSS DS-1

One of the best pedal ever made.
The Boss Ds-1.
I just received from Australia the original DS-1 that was introduced in 1978. I was really curious to hear it as in 1994 the Toshiba pre-amp components used in the original circuit board were at the end of the production cycle and they were replaced with other parts that actually changed the tone and original characteristics of the pedal.
I will soon publish the video of the comparison between the 2 versions and also with the Keeley and JHS MODs.
Stay tuned.
