Subtle Volume Control

The E.W.S. Subtle Volume Control (SVC) is a device designed based on Scott Henderson's idea, providing precise control of overall volume without affecting gain. The SVC is intended for use in the amp effects loop, allowing volume control without altering the preamp gain. It can also be placed between the last pedal and the amp, although maintaining consistent gain while changing volume may be less effective in this setup.

The technical specifications of the SVC are as follows:
- Potentiometer Resistance: 25k ohm
- Size (W/D/H): 120mm x 60mm x 55mm (4.7 x 2.4 x 2.2 inches)
- Weight: 190g (0.4 lbs)

The SVC is designed to be foot-operated and placed on a pedal board. As it does not require a power source, such as batteries, it is convenient for use in various setups. The low impedance signal from the amp effects loop ensures that the cables running from the amp to the SVC do not degrade the sound quality.

The SVC can be used in different configurations, including with low impedance effects, volume pedals, mixers, and more, offering flexibility in integrating it into a setup. Additionally, the SVC is priced at $60 and is distributed by Prosound Communications Inc.

Overall, the E.W.S. Subtle Volume Control (SVC) is designed to provide precise and subtle control over volume levels, enhancing the user's ability to mix live performances with the band seamlessly.
