Key Features

  • ACOUSTIC-SPECIFIC STEREO SOUND – FOR PRACTICE & SMALL GIGS: AC-20S is voiced specifically for acoustic guitars with 20W stereo amplifier driving two 4-inch speakers. It delivers clear, natural tone with sparkling highs, warm mids, and a balanced low-end. 20W is ideal for home practice, small shows, and gigs. For larger venues, consider the AC-40S.
  • 3 BUILT-IN DSP EFFECTS – CHORUS, DELAY & REVERB – USE TOGETHER OR SOLO: Use them individually to add subtle texture, or combine them for rich, layered soundscapes. No extra pedals needed. Tip: Pair with a compressor pedal for even better tone.
  • DEDICATED MIC CHANNEL WITH REVERB – SING AND PLAY AT THE SAME TIME: A separate microphone input with its own reverb control lets you shape vocal tone while practicing. The mic channel is optimized for dynamic microphones — clear, natural vocals without the need for external preamps. Note: Mic input does not support phantom power.
  • BLUETOOTH, AUX & USB-C RECORDING – STREAM, RECORD, AND CREATE: Stream backing tracks wirelessly via Bluetooth 5.0 or connect device using the AUX IN jack. The USB-C port supports OTG live streaming and direct recording to phone or PC for content creators and practice sessions. Plug in headphones for silent practice — speakers mute automatically. Note: Bluetooth and AUX IN cannot be used at the same time; USB-C does not charge external devices.
  • PORTABLE, BATTERY-POWERED & BUILT TO LAST: Built-in rechargeable battery lets you play anywhere up 3-6 hour — from your living room to the park. At just 5.4kg (12 lbs), it's easy to carry and store. Solid construction and intuitive controls make it reliable and simple to use.
