They are either v5's or v6 IC muffs(some are v5 some are v6) with the tone and sustain pre set(but you can change it to what you like easy enough) They shouldn't be sold for over $160 bucks. I can get one right now for that, its been for sale for that for 2 years.LOL
They also come in reverse graphics versions which are blue, white and black.
They have a full size PCB inside with places for all three pots but instead of having all three pots they use one for vol, and resistors to set the sustain and tone. The tone is switchable with the slide switch. Either muffled or beehive. 😆 The sustain is set to various degrees depending on the resistor value chosen during building. If you're a set and play type like me these are great. you can solder in what ever value resistors you like to set the sutain and tone to your likeing then never have to bother with it again. if you fidle with the knobs all the time they aren't for you. unless you are handy with diy and soldering etc.
