BOSS OD-1 OverDrive LiveSPICE (Calibrated)

Probably the world's first overdrive pedal. The BOSS OD-1 is the ancestor of all tube screamer-type pedals. Manufactured in Japan from the late '70s to mid '80s and eventually discontinued in favor of the also legendary BOSS SD-1. Nowadays it's very rare and sells from moderately expensive to below Klon-like expensive depending on the revision. My schematic is based on the dual op-amp/BJT buffer version, which is the "inferior" version, according to many internet-dwelling corksniffers. I might revisit at some point with the quad op-amp version to see if they behave differently sonically. This was done with LiveSPICE instead of LTspice as a continuation of learning the workflow of creating calibrated captures using the former. Training files were rendered with LiveSPICE settings set to 8x oversampling and 64 iterations for the highest quality possible. • Sound character: Very mid-forward, with a response similar to the SD-1 and TS808 we all love. It lacks the Tone knob seen on its derivatives though. Instead it has a fixed mid to treble response. • Settings: Five captures total. There are two captures with minimal gain and full volume that aim for boost usage. Then there are three more captures that aim for saturation with drive set at 5, 7 and 10, while also rolling the volume knob back a little. • Calibration: Calibration metadata is already embedded in the NAM files. Details: Input: +10.4 dBu ≘ 0 dBFS | Output: +10.4 dBu ≘ 0 dBFS You only need to enter the headroom of your audio interface's input in dBu inside your NAM host. ⚠️ Note: These captures are (input AND output) CALIBRATED! Preferably use an amp capture with calibrated input after them. If you don't know how to set up calibrated NAM chains watch 2dor's tutorials "𝗡𝗔𝗠 𝗰𝗮𝗹𝗶𝗯𝗿𝗮𝘁𝗶𝗼𝗻 & 𝗰𝗮𝗹𝗶𝗯𝗿𝗮𝘁𝗲𝗱 𝗽𝗿𝗼𝗳𝗶𝗹𝗲𝘀: 𝗾𝘂𝗶𝗰𝗸 & 𝗲𝗮𝘀𝘆 [𝟮𝟬𝟮𝟱]" & "𝗦𝘁𝗮𝗰𝗸𝗶𝗻𝗴 𝗰𝗮𝗹𝗶𝗯𝗿𝗮𝘁𝗲𝗱 𝗡𝗔𝗠 (𝗡𝗲𝘂𝗿𝗮𝗹 𝗔𝗺𝗽 𝗠𝗼𝗱𝗲𝗹𝗲𝗿) 𝗽𝗿𝗼𝗳𝗶𝗹𝗲𝘀" on YouTube OR read the "𝗡𝗲𝘂𝗿𝗮𝗹𝗔𝗺𝗽𝗠𝗼𝗱𝗲𝗹𝗲𝗿𝗣𝗹𝘂𝗴𝗶𝗻 𝘃𝟬.𝟳.𝟭𝟮 𝗶𝘀 𝗿𝗲𝗹𝗲𝗮𝘀𝗲𝗱" blog post on the Neural Amp Modeler website. Of course you are free to experiment! Using the Raw option will also preserve the unit's output that is relative to your input signal or just use whatever levels you like more! The calibrated options will just give you the results that are closest to real life. ⚠️ Note 2: These captures are NOT derived from the physical hardware but from circuit simulation done in a SPICE environment. I just want to be transparent about that and not mislead people. Of course that doesn't mean they can't sound just as good, provided they are done correctly.
