# Roland TB-303 and TR-606
“This complete system is like brand new. Only used by my son for about 10 hours at home before he went off to College. A friend of his had this same system and played acid and hard rock, with this combo it was unbelievable, great sound and once he got ust to it it was easy for him to use. I packed it away in the house in 1983. He got married and lost interest in music. The units are in the same box they were purchased in. Including the Synchronizing cable, two power supplies, the carrying cases, the instructional manuals including elementary and advance courses on how to use the system. I had taken out the batteries when I put them away. I have installed new batteries and checked out the system per the owners manuals. ” Link
