NuX AC-25 Portable 25-Watt Acoustic Guitar Amplifier – Battery Powered | No Limit Guitar Co, Idaho Falls
The NuX AC-25 is a compact, 25-watt acoustic amplifier built for musicians on the move — a feature-rich, battery-powered acoustic amp that delivers rich, natural sound from a 6.5" NuX Custom speaker with advanced amp modeling, built-in reverb effects, Bluetooth connectivity, and an onboard drum machine in a portable package that weighs just 11 lbs. and runs up to 4 hours on its built-in rechargeable battery. Separate channels for acoustic guitar and microphone with independent volume and tone controls, two amp models (Stageman and LBox) for distinctly different tonal characters, Plate and Hall reverb, AUX input, headphone output, and line output round out a specification that covers busking, small venue performance, home practice, and singer-songwriter applications equally well.
Product Overview
The AC-25's dual-channel design is the specification that makes it genuinely useful as a complete performance solution rather than just a practice amp. Channel 1 accepts the acoustic guitar with a 1M ohm input impedance suited for piezo and magnetic pickup sources, while Channel 2 provides a 2K ohm impedance microphone input — each channel with its own independent volume and tone controls so the balance between instrument and voice can be dialed in precisely without compromising either channel's tonal character. For the solo acoustic performer who needs to sing and play simultaneously through a single portable amp, the AC-25's dual-channel configuration removes the need for a separate PA or mixer entirely.
The two amp models provide two meaningfully different acoustic amplification philosophies. Stageman mode adds warmth and richness to the acoustic signal — a fuller, more colored sound suited to singer-songwriters who want that classic, full-bodied acoustic amp character that adds presence and body to fingerstyle playing and strummed chords. LBox mode delivers a clean, transparent, uncolored sound that preserves the guitar's natural acoustic character as closely as amplification allows — the choice for players who want to hear their instrument rather than the amp's personality. Both modes can be enhanced with the built-in Plate or Hall reverb effects for spatial depth and ambiance without external effects units.
The built-in rechargeable battery delivers up to 4 hours of performance runtime — sufficient for a complete busking session, a short venue set, or an extended practice without access to a power outlet. Bluetooth connectivity serves two functions: audio streaming from a phone, tablet, or computer for playing along with backing tracks or recorded music, and app connectivity for expanded tone control and preset management beyond what the onboard controls provide. The built-in drum machine adds rhythmic backing for solo practice and performance — keeping time and adding structure to solo sessions without a separate device or metronome. AUX input, headphone output for silent practice, and line output for recording or PA integration complete a connectivity suite that handles a wide range of practical performance and practice scenarios.

Key Features
25-Watt Acoustic-Optimized Output with 6.5" NuX Custom Speaker
