It's just estimates based on serial numbers so it's not 100% accurate. It could very well be that my DS-1 number is a couple of hundred thousand too few
i would have guessed DS-1 and MT-2 to be #1 and #2.
everyone wants a cheap distortion pedal. angry 16 year olds wanna shred.
if those figure estimates are accurate i would say that is a very good display of the exponential growth of guitar playing as a hobby as well as what pedals boss has made available over the past 15 years.
The DS-1 was certainly seen everywhere back in the day. The SD-1 well .....Every guy I ever saw way back then with a Tubescreamer also had a yellow Boss pedal , if memory doesnt play tricks on me
