Substitutes same kind

Diodes of the same kind; for clipping, the forward drop is what you hear. The figures are read off each part's datasheet (this one's from page 1), typical where the sheet gives a typical value, otherwise the maximum. Closest first; the last column says what differs. A different part can change the sound, and a circuit may lean on one particular figure, so read the build document's notes before you swap.

Vf is specified only at 1 A and above, so the sheet says nothing about the low clipping knee.

BAT85S0.24 V @ 0.1 mA0.2 A30 V5 ns10 pFDO-352DO-35. Very low-drop glass Schottky: 0.24 V at 0.1 mA, 0.32 V at 1 mA.
BAT420.4 V @ 10 mA0.2 A30 V5 ns7 pFDO-3518DO-35. 30 V Schottky in glass, about 0.4 V at 10 mA.
BAT430.33 V @ 2 mA0.2 A30 V5 ns7 pFDO-352DO-35. Same die as the BAT42 but specified at low current: 0.26-0.33 V at 2 mA.
BAT460.25 V @ 0.1 mA0.15 A100 V10 pFDO-35115DO-35. Low-drop Schottky clipper, about 0.25 V at 0.1 mA, with a 100 V rating.
1N60P0.24 V @ 1 mA0.05 A45 V1 ns6 pFDO-3532DO-35. This 1N60P is a Schottky, not a germanium point-contact diode, though it is often sold as a germanium substitute.
BAT410.4 V @ 1 mA0.1 A100 V2 pFDO-35113DO-35. About 0.4 V at 1 mA, close to a germanium clipping drop with far lower leakage.
1N57110.41 V @ 1 mA0.033 A50 V2 pFDO-354DO-35. Low-capacitance 70 V Schottky with very low leakage, but only 33 mA average current.
