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

Yes, this is a smaller ball launcher … It is for her SHORT Game! Love it AND the squeaky baseball that came with it is A-HIT!! Our black golden doodle, Josie, carried that around for hours … batting it around, jumping on it, resting with it right-next-to-her. For your pup’s LONG game, purchase the longer launcher. GAME-on!

Works great with tennis balls

I have a pretty large yard, and this thrower is great for my little Jack Russel puppy. It even picks up ball without having to touch all the spit.
