I agree. A bit less Josh Scott, and a bit more of the other folks would have been nice, too. It was also a bit America-centric. Granted, much of the pedal industry IS American (if made in China or Indonesia), but a short visit to the effectsdatabase site will show you that there are MANY pedal companies and innovators all around the world. A quick pic of the Gamechanger guys (Latvia) and a smidgen of Japan to supplement all the British stuff doesn't really capture just how world-wide stompboxes are. For instance, Greece is now a heavy hitter in the field, as is Canada. Plenty of stuff came from Italy in the early days, and Japan has had entire periodicals devoted to pedals for decades.
One thing it did capture adequately was Craig Anderton's influence on the field/industry. The effectsdatabase.com site has an ever-expanding (355 at the moment) interviews with pedalmakers (
https://www.effectsdatabase.com/interviews/brands#list ), and one of the questions is how they got started. A not insignificant number of them cite Craig's "Electronic Projects for Musicians" book, and the DIYstompbox site as what kickstarted them. And while we're at it, omitting Bart Provoost, who maintains the Disco Freq's effectsdatabase site, is a major oversight, since he is aware of probably more pedals than anyone else in the entire planet. One of the things he does is provide "family trees" and equivalents. So, if a manufacturer like Ross or Loco simply reuses someone else's design with a packaging change or one or two minor tweaks, links to those pedals will be provided to let you know what it is a sibling of. For example, look at this link:
https://www.effectsdatabase.com/model/locobox/70s/choker#reviews . Many brands we may treat as different are simply using licensed circuit designs, and often circuit boards, under a different brand name and packaging. Check out
this listing for the MANY companies that produce/d a copy of (what we think of as) the Univox Superfuzz (
https://www.effectsdatabase.com/model/companion/fy6#related ). In '76 or '77, I bought myself a Fernandes Funky Filter for $25. It was actually a Mu-Tron III, being sold as a rebranded pedal; ostensibly licensed from Musitronics. I order for Bart to provide this information, he has to be aware of the kinship relations within the pedal universe. That's why I find his omission a serious shortcoming.
