Hand Made TB-303 Clone

via wire to the ear where you can find more info.

New Old Stock Boss RPH-10

via swissdoc:

"just got this in the mail today, a brand new, mint in box, New Old Stock Boss RPH-10.
Opening this up was like in a time machine, the flyer, the sticker etc. 23 years old if I take the printed in 1985 label from the manual.

Will add a decent phasing to my Blofeld ;-)"
