The Marshall AS100D is a quality amplifier that has proven to be invaluable to a great many people. Whether you're a one man band performing at open-mic nights, or even an Irish Jig trio, the AS100D contains everything you'd need to produce a high quality professional sound. You get 4 channels with this beauty, including 2 instrument channels, 1 vocal channel, and even a stereo channel for external audio devices, so you could play along with backing tracks or play CD's during your set breaks!

As everybody knows feedback from mics can be harsh on the ear, and unfortunately with acoustic music it's more likely to happen too. Thankfully those clever chaps at Marshall have built in an effective Anti-Feedback system to eradicate those unwanted howls! The AS100D also has some great sounding FX built in sweeten your sound.

If you're anything more than a 2 or 3 piece group, you may want to consider purchasing a small P.A system instead which would allow you a bit more freedom for vocals etc. However, for intimate sounding performances with say up to 2 instruments and a vocalist, the AS100D is absolutely perfect, with enough power to comfortably project your music at small/medium sized gigs. Top marks!

Here's what Marshall say about the AS100D 2x50W Acoustic Guitar Amp

For the acoustic player who wants it all, we offer the comprehensively featured and powerful AS100D - a 50Watt + 50Watt, 2x 8 inch combo with two high fidelity, polymer dome tweeters. The AS100D has been specially created for use with a variety of acoustic instruments and now boasts new and improved speakers conceived by our design experts in conjunction with Celestion. Between its four channels, this combo has the flexibility to handle instruments with piezo transducers or magnetic pick-ups, plus microphones, for both vocal and instrument reproduction. For those using two pick-ups via a single stereo jack, the two main Acoustic Channels (1 and 2) can be linked together via a 'Link' switch, affording you independent Volume and EQ controls for each pick-up. The other two channels are a dedicated Microphone channel (3) and an Auxiliary channel (4), the latter of which has phono (RCA) stereo inputs specifically for use with external audio equipment. The AS100D houses an internal limiter to ensure you can achieve maximum output while your sound remains distortion free.

Even though the AS100D's 50Watt + 50Watt stereo configuration offers more than enough power for many typical acoustic music venues, a stereo pair of balanced XLR DI outs and Line Outs allow you to connect directly to an external PA system for larger venues. When playing live, one of the most difficult aspects of amplifying acoustic instruments is unwanted feedback. To help eliminate this, the AS100D features several 'anti-feedback' controls, including an individual Phase switch on channels 1, 2 & 3, plus two frequency controllable Notch Filters with selectable extra depth for channels 1 & 2.

The superb quality of the 16 built-in, adjustable stereo digital effects (10 Reverbs, Delay, Chorus & more) adds an entirely new dimension to the already wide range of sounds this professional combo has to offer. Additionally, there is also a stereo Parallel Effects Loop, complete with Level Control, on the rear panel. Compact and portable, the stylish AS100D offers great flexibility and is the ideal amplifier for the acoustic player who wants the highest quality performance, with absolutely natural tonal reproduction.
