If you are even remotely interested in modular and eurorack synthesis, then Doepfer is a name you certainly know of. This brand is the epitome of "cheaper is not always less quality' if you ask me.
The doepfer range has been available for many years, and the new vintage styled modules are not different from their initial grey counterparts, but do look a lot nicer in my opinion :-)
The module is well built , solid quality, and sounds great. It has all basic features you'd expect, and is easy to install and use.
The doepfer VCO are great, and sound good, even compared to expensive modules.
This is a good option for both the experienced as beginning eurorack enthousiast.
