# Sequential Circuits Multitrak
“I am selling a Sequential Circuits Multitrak. I have replaced the battery and also did the battery drain fix modification so that the new battery will last 7 years instead of 3 months, you can see the picture of the battery mod i did. It is a common problem on most multitrak’s the battery drains in less than 3 months. The link for the battery mod is http://www.k5000.org/gear/MultiTrak_battery.html. I also got a brand new custom made power supply built for the multitrak. These power supplies are not made anymore, they are rare and hard to find and to get a brand new one made would cost at least $200. I had mine built from a professional technician. The physical condition is pretty much perfect, with no major scratches or marks on it as you can see from the pictures. Everything functions as it should. There are no presets on it, but the battery does work so you could load all the presets if you wanted to.” Link
