Up for sale is an early 1970s Roland AS-1 Sustainer in good working condition. This is a rare and highly collectible piece from the dawn of Roland's effects pedal development—years before the introduction of the famous BOSS compact pedal line.

The AS-1 is an excellent optical compressor/sustainer, delivering smooth compression, increased sustain, and a natural feel that works beautifully with clean or overdriven tones. Unlike some information circulating online, this unit does not feature a distortion effect. Its purpose is compression and sustain, and it performs that role exceptionally well.

Features:

• Original early 1970s Roland AS-1 Sustainer
• Good working condition
• Smooth optical (opto) compression circuit
• Natural sustain and dynamics enhancement
• Pre-BOSS era Roland design
• Runs on two 9-volt batteries
• Rare vintage Japanese effects pedal
• Excellent for guitar, bass, and studio applications

The AS-1 represents an important chapter in effects pedal history. Long before compressor pedals became commonplace, Roland was experimenting with innovative designs that helped pave the way for many of the effects players take for granted today.

Whether you're a collector of vintage Japanese effects, a studio musician looking for unique analog compression, or a guitarist who appreciates historically significant gear, this pedal is a wonderful addition to any collection.

Please review all photos carefully and feel free to contact me with any questions. The pedal will be packed securely and shipped promptly.

A rare opportunity to own an early Roland effects pedal from the pre-BOSS era—an excellent-sounding optical compressor and a genuine piece of guitar pedal history.
