Build Your Own Clone
The BYOC Li'l Yellow OD is a clone of the very first Made-in-Japan version BOSS OD-1, except much, much smaller. It has the single quad op amp circuit and features the MC3403 chip, not the double dual op amp circuit with transistor buffers that the later versions have.
Features all through-hole components, and full-sized, panel-mounted hardware.
NOTE: Because of limited space, you cannot use knobs with skirts larger than 16mm. We recommend using 1900, Mini Fluted, Mini 1510, or BYOC style knobs.
