There are so many copies of TB-303s, Moog modules and other 'famous' circuits contained in Eurorack modules now, the genie's out of the bottle. Doepfer, Synthesizers.com, and a myriad of 'boutique' manufacturers are already doing it so one more entering the market to make legal 'evocations' (or whatever they want to call them) doesn't bother me.
I’d still argue the Eurorack was a different thing, there is some originality of thought there, a re-contextualising of classic technology to a new environment and mindset.
I realise my argument kind of fails as soon as one looks at the guitar market which is littered by cheap crappy copies of Strats, Les Pauls, Telecasters, Jazz and Precision basses etc. It is interesting to look at the history of copy guitars, especially the Japanese ones. Many of the main factories (Matsumoku, Fujigen etc) started in the ‘60s making pretty dreadful guitars which were kind of influenced by Fender, Gibson, Burns, Mosrite etc, but their own thing and of a really poor budget quality that in many cases were barely playable. The next phase in the ‘70s was to relentlessly copy Strats, Les Pauls etc, to forensically copy every detail of the best vintage US guitars which led to the ‘lawsuit era’ as they were actually making far better Stats and Les Pauls than Fender or Gibson were at the time. Then things got really interesting and they took everything they had learned and started doing their own thing again. My favourite guitar at present is a ‘78 Yamaha SC1200 which kind of looks a bit Strat-like, but is very much its own thing with a thru-neck, bizarre pickup switching, very different pickups etc. It is an evolution, one that led to all of the high-tech, high-craft Japanese guitars of today. Maybe we’ll see Behringer etc follow this path, I don’t know.
To be honest it is the copying of branding and what I’d have thought were trade-marks that surprises me the most. Even the most legendary Tokai ‘lawsuit-era’ Strats were called ‘Springy Sound’, they never had the balls to write ‘Stratocaster’ on the headstock, so I don’t quite understand how Behringer can call something a ‘Wasp’ in EDP’s unique font etc.
