The Mooer SD amplifier series is a harmonious marriage between Mooer's famous digital preamp technology and a new take on traditional solid-state Class A/B amplification techniques, that deliver professional 'tube like' performance, touch and feel, at entry level prices. Each model in the Mooer SD series comes fully loaded with a bunch of special-features and effects (including 8 overdrive and distortion effects, 25 amp head simulations, 9 modulation effects, 5 delay effects and 6 reverb effects), that provide everything you need to craft incredible guitar tones for creating music on-stage or in the practice room. These tones can be stored within 40 preset slots. The SD amps have a unique Jam section that contains a whole suite of tools for solo performers and creative aficionados alike, such as an integrated looper, syncable drum machine and Bluetooth or 3.5mm Aux input connection for playback of your favorite audio tracks from an external device. The Mooer SD30 comes with a 8" custom-built guitar speaker, designed to deliver rich harmonics and enhanced feel with clarity, articulation and dynamics throughout the amplifiers full volume range.
