Early black label, long dash OD-1 with the chip everyone is after - the original TL4558P IC, producing that iconic overdrive that purists covet with clearer, tighter lows, stronger attack, slightly more open sound (less mid-focused) - an opamp favoured by guitarist Jim Weider. Made in Japan.
Serial number sticker has been removed with a previous owner's name written in marker where it would have been. Batch 0000. Requires ACA power (12 volt centre negative pin).
