Pioneer Reverberation Amplifier SR-60

Description:

The Pioneer SR-60 is a vintage reverberation amplifier designed to add spatial depth and ambiance to audio signals. It uses a bucket brigade device (BBD) to create echo and reverberation effects, allowing users to adjust the level and decay of the added ambience. It can create effects like standard reverb, echo, and sometimes a "duet" effect.  

Specifications (based on available information):

• Type: Reverberation Amplifier
• Effect Type: Reverberation, Echo, Duet
• Technology: Bucket Brigade Device (BBD)
• Input: RCA
• Output: RCA
• Controls: Reverberation Level, Echo Level/Time (likely), other effect parameters
• Power Output (Amplifier Section): While termed an amplifier, its primary function is effect processing, so a significant power output for speakers is unlikely. It's designed to be inserted into the audio signal path. Some models might have a small amplifier section for the reverb effect itself.
• Dimensions (W x H x D): Approximately 435 x 133 x 330 mm (based on similar Pioneer components of the era)
• Weight: Approximately 8 kg
