Doepfer A-101-6 Opto FET VCF/PhaserA 101 6 is a new filter module that uses so called "Opto FETs" to control the frequency. Opto Fets are similar in structure to Vactrols , but use is made of photosensitive field effect transistors ( FETs ) instead of photosensitive resistors (LDRs). Opto FETs incorporate a photosensitive FET and a light emitting diode in a common, light tight housing. The advantage over Vactrols is that Opto FETs are much faster than LDRs and thus very short attacks

You are getting what you pay for: the color of the dial is amazing. It looks so stylish and can really accessorize an outfit. The packaging of the watch was very nice and it came with tools to adjust the size of the watch. However the links color is not the best color and quality. The watch feels light but in a cheaper feel. I’ve ordered other watches from Amazon that in my opinion were nicer and felt and looked high end. I got this watch on sale for Black Friday but I’m not sure if I would pay full price for it.
