Selling my original Teenage Engineering OP-1.

The OP-1 is in excellent cosmetic condition, with a very clean keyboard, encoders and casing, as shown in the photographs. It has been kept with a clear protective cover, which is included in the sale.

It has seen very little use over the past few years, largely because the OP-1's workflow no longer fits into my practice. Rather than leaving it unused and with Teenage Engineering seemingly more interested in making everything except synthesizers these days, I figured I'd do my part and put one of their actual synths back into circulation.

It is running firmware V225 (R.00225), an earlier version of the original OP-1 firmware which I have deliberately left installed rather than updating. The purchaser can update the firmware if preferred.

The OP-1 is fully functional and works perfectly, with no known faults or issues.

Included:

• Original Teenage Engineering OP-1 synthesizer (not the OP-1 Field)
• Clear rigid protective cover, as pictured

No cables are included.

The manufacturing year and hardware revision have not been verified, so I am not advertising it as a particular revision but I believe it is a Rev 1 based on firmware date.

Located in Melbourne. Local pickup welcome, or tracked and insured postage with Auspost.

Can also ship outside of Australia at buyer's expense.

Happy to provide additional photographs or answer any questions.
