Hotone Ampero Press 25kΩ Edition SP-30H – Passive Volume and Expression Pedal for Your Pedalboard The Hotone Ampero Press 25kΩ Edition SP-30H is an innovative pedal that combines the functions of a passive volume controller and an expression controller within a single compact enclosure. This solution is designed for musicians who require precise signal control without consuming excessive space on their pedalboard or requiring additional power cabling. Product Features Dual functionality in one pedal – The Ampero Press SP-30H offers independent volume and expression outputs, meaning you can simultaneously adjust signal levels and control parameters of effects or other compatible devices. Passive construction eliminates the need for a power adapter or batteries, significantly simplifying the configuration of your entire rig. High-quality potentiometers ensure smooth, accurate response to every foot movement, while the aluminum alloy enclosure guarantees durability even under intense stage use. The SP-30H version is equipped with an expression potentiometer with a resistance of 25 kΩ, making it dedicated to devices requiring exactly this value. Professional Control Without Compromise In the world of guitarists and multi-instrumentalists, space on a pedalboard is a scarce resource. The Hotone Ampero Press 25kΩ Edition SP-30H solves this problem elegantly – instead of two separate pedals, you receive one compact controller that performs both functions simultaneously. The volume path, based on a 100 kΩ potentiometer, offers classic, linear signal attenuation, ideal for dynamic live playing and studio work. Meanwhile, the expression path with a 25 kΩ potentiometer allows control over parameters such as delay time, reverb mix, wah, or pitch shift in compatible devices. The passive design is another advantage of this solution – the lack of need to connect a power supply means fewer cables on stage, a lower risk of failure, and easier integration into an existing setup. You don't need to worry about an extra power outlet or battery status during a concert. The pedal works immediately upon connection, a feature appreciated by every musician who values reliability. Integration with the Hotone Ampero II Stomp (from software version 1.1.0) opens up extensive programming possibilities for expression control. You can assign expression control to any effect parameter, creating dynamic, expressive tones that respond to every movement of your foot. At the same time, the volume path remains independent, giving you full freedom in shaping the dynamics of your playing. Applications Real-time control of guitar or bass signal levels during live performances Programming expression controls for multi-effects processors, such as the Hotone Ampero II Stomp Reducing the number of pedals on a pedalboard in mobile stage setups Studio recordings requiring smooth control over dynamics and effect parameters Multi-instrumentalist rigs where every centimeter of space counts Detailed Technical Specifications Volume path potentiometer: 100 kΩ Expression path potentiometer: 25 kΩ Outputs: independent (volume and expression) Construction: passive, no power supply required Dimensions: 81 × 162 × 51 mm Weight: 430 g Enclosure: aluminum alloy Compatibility: devices requiring a 25 kΩ expression pedal, including Ampero II Stomp (software 1.1.0+) Materials and Build The pedal enclosure is made of aluminum alloy, providing an excellent strength-to-weight ratio. Compared to full-steel volume pedals, the Ampero Press SP-30H is significantly lighter, which translates to easier transport and less strain on the entire pedalboard. At the same time, the aluminum construction is robust enough to withstand daily stage use. High-quality potentiometers used in both paths guarantee repeatability and control precision – every foot movement is faithfully reproduced at the output, without jumps or non-linearity. Package Contents Hotone Ampero Press 25kΩ Edition SP-30H Volume and Expression Pedal Summary If you are looking for a way to simplify your pedalboard without sacrificing full control over dynamics and effect parameters, this dual-function passive pedal is the answer to your needs. Compact dimensions, low weight, no power requirement, and precise potentiometers make it a reliable tool for both stage and studio musicians. The Hotone Ampero Press 25kΩ Edition SP-30H is proof that less is more – one pedal, two functions, zero compromises.
