Maxon OD9 Boost

NAM model captured from a Japanese-made Maxon OD-9, dialed in as a clean boost and calibrated for consistent response. The Maxon OD-9 follows the classic TS9-style circuit, built with the JRC4558D chip and true bypass switching. This removes the FET-based switching components found in the original TS9 from the signal path, resulting in a slightly more direct and uncolored response. It is hand-wired and hand-soldered in the traditional style. This capture uses a straightforward boost configuration with the overdrive set to minimum, balance maxed, and tone at 1 o’clock. The result is a tight, mid-focused push with a familiar Tube Screamer character—ideal for tightening low end, adding clarity, and driving an amp without introducing significant additional gain. Boost settings: Overdrive: min Balance: max Tone: 1 o'clock The models are calibrated for reliable gain staging. Reamp chain: Motu M4 > Lehle P-SPLIT III > Maxon OD808 > Motu M4 This capture focuses on delivering the OD-9’s classic midrange emphasis and clean boost behavior in a simple, mix-ready form. Two A2 files are available. One trained locally and the other trained on T3K.
