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

I really like this turtleneck sweater! The material is soft, warm, and feels high-quality without being too heavy. It has just the right amount of stretch, so it fits comfortably without feeling tight around the neck or sleeves. I’ve worn it both casually with jeans and dressed up — it looks great either way. I order another one in a different color.
