The Ashdown Studio 4 is an ultra-compact, battery-powered bass combo amplifier engineered to provide reliable low-end performance in a highly portable format.

Advanced Practice Features & Tone Shaping

Rated at 3 watts and equipped with a single 4-inch speaker, this lightweight unit is designed to produce a deep, resonant bass response that exceeds its physical dimensions. 

It serves as a practical solution for mobile bassists requiring a grab-and-go tool for silent practice, backstage warmups, home use, or outdoor jam sessions.

The amplifier integrates modern connectivity options, including built-in wireless audio streaming alongside a standard line-in jack, allowing users to stream or plug in backing tracks directly for play-along practice. 

For private sessions, an integrated headphone output disconnects the internal speaker for silent monitoring. 

Frequency adjustments are handled by a dedicated 3-band equalisation section, providing precise control over the bass, middle, and treble ranges to shape the instrument's output. 

Additionally, an extension output enables connection to larger, external speaker cabinets when more volume is required.

Portable Power & Rugged Engineering 

Power delivery is managed via a built-in rechargeable 9V battery system, which provides multiple hours of continuous operation on a single charge. 

The physical chassis measures 160 mm in height, 160 mm in width, and 100 mm in depth, with a total net weight of 1 kilogram. 

Built according to established Ashdown engineering standards, the rugged outer enclosure is constructed to withstand the wear of frequent transport while maintaining structural integrity over extended portable use.
