OVERVIEW

Clear natural sound and the power to perform.

This Marshall AS100D Acoustic Combo Amp is the one to have. Specially designed for use with a variety of acoustic instruments with or without pickups. Its four channels give you the flexibility to handle piezo transducers or magnetic pickups, a mic for vocals or instruments, and external audio equipment via a phono input channel. Channels 1 and 2 have separate EQ and level controls but also may be linked. 2x50W stereo power gives you plenty of oomph for stage performance, and a balanced line out allows direct connection to a PA. The Marshall amp has a built-in digital reverb, delay, and chorus that add dimension to your sound, and a balanced parallel effects loop with level is included. Anti-feedback controls include a phase switch and notch filters for each channel with selectable extra notch depth for channels 1 and 2.

FEATURES
  • Channels for both piezo and magnetic pickups
  • 2x50W of power
  • 2 - 8" speakers

The Marshall AS100D acoustic soloist amplifier is a very versatile and finely crafted piece of equipment. Instead of simply listing and commenting on its many features, I would like to focus on my experience with the amp and some of its attributes. On occasion, I will compare it to the new Fender Acoustasonic 150 stereo amp, which I considered and tested before purchasing the Marshall. In general, the AS100D is exceptional as an acoustic instrument amp. It seems like the engineers at Marshall really put some thought into the design of this amp. It's very versatile and seems to accommodate just about any acoustic instrument scenario. I play several acoustic guitars through it (Taylor, Alvarez-Yairi, Takamine), and each sounds spectacular. Likewise, the vocal channel is clear and sounds great. I run my live vocals through a Shure SM58 microphone. In the past, I used two old Fender Acoustasonic SFX amps in a stereo rig setup. They sounded great, but weighed a ton and had no direct-out capabilities. Ultimately, I sold both Fenders and bought a compact Yamaha PA system. To increase the quality and versatility of my sound, I decided to supplement the PA with an acoustic amp. As forementioned, I tested both the new Fender Acoustasonic 150 and the Marshall AS100D, ultimately purchasing the latter. Although the AS100D has very clear and usable stock effects (reverbs, delays, etc.), some users may require external effects for more control and versatility. This leads to my main point. One of the great features of this amp is the stereo FX loop. Compared to the new Fender Acoustasonic stereo 150, the AS100D has both right and left stereo return inputs, whereas the Fender only has one stereo input that requires a "Y" adapter. The Marshall also has a level control for the FX loop, which is very handy for adjusting the signal running through the loop. In addition to its primary use as an acoustic instrument amp, I have found that the AS100D, with its stereo capabilities, also sounds absolutely stunning with an electric guitar when running a quality signal processor through its FX stereo loop. The AS100D has pristine clean amplification, and this really complements the signal processor and amp simulations. I own and have used both a Line 6 POD XT Pro rack system and a Digitech RP500 with this amp with good results. Of course, when using an electric guitar and effects processor through any acoustic amp or PA, careful attention must be paid to equalization for best results. The AS100D is no exception, but what surprised me is that it doesn't require extreme tonal adjustments. I will, however, state that I am not a heavy metal guitar player, and would guess the amp would not be ideal for that style of playing where high gain and creative feedback is needed. But for classic rock and clean settings, it sounds wonderful. Amp simulations I have used with good results on the AS100D include the following: Fender Twin Reverb, Fender Bassman, Vox AC30/15, Supro, Marshall (early), and boutique clean models. My criticisms? The amp is somewhat heavy (47 lbs), but it's such a versatile and beautiful piece of equipment, I don't mind the weight. The Acoustasonic 150 is half the weight, but just doesn't feel solid. In fact, it felt a bit flimsy. I am disappointed that Marshall doesn't offer a custom cover. Some reviewers voiced disappointment over the 15V (as opposed to 48V) phantom power, but I had no problem in my limited use of condenser microphones with the amp. I guess one would need to test out any condenser microphone before buying. In conclusion, the Marshall AS100D is a solid, great-sounding amp for acoustic instrument and voice amplification. It also doubles as a stereo system for electric guitars.
Expensive, but I believe it is worth the extra money for its quality and versatility.

Thought this amp was the cat's meow until it came time to start replacing speakers. Blew out the horns in a relatively short period. Original horns were discontinued. The new replacement horns required drilling larger holes in the mounting plate which required purchasing a 3.125" hole saw. Now I'm replacing one of the 8" speakers. Not able to find it online (same problem with the horns) and will have to go through Marshall to special order it. What good is a product if you don't have parts readily available? For the gigging musician, this would be unacceptable. Will give this a "don't buy" recommendation solely because of the tight control by Marshall on replacement parts and shipping time.

      Comments about Marshall AS100D 2x8 Acoustic Combo Amp:

      First the negatives -- input/output sections. Hey guys -- RCA jacks on the aux in? Really? MP3 players use mini jacks. Add one! Carrying around a collection of adapters is sorta asking for something essential to be left behind. As for outputs -- really guys? Have you heard of USB? ADD ONE! Beyond those two negatives this amp is a smash hit, for reasons explained below.

      I've been in music since S & H Green Stamps got my first guitar from Montgomery Wards. In this case, I wanted an all-in-one. Here's how it's being used.

      Ministry: For a home fellowship, we wanted multiple inputs (piano/organ, microphone, guitar & MP3 player). Done. For a small meeting room, this nails it. Preacher on the mic, pianist, or canned music with plenty of headroom in other channels. Sound is top-shelf. As for music quality-- every frequency right where it is needed. Put a second mic up there for audience questions/participation, and route the audio output over into the video recording computer (Wirecast)and you can do live streaming. (Just figure out how to get the 1/4" outs into USB.)

      Education: Direct out from laptop into amp (just remember the RCA adapter) and the sound is perfect. USB the laptop to a projector and you are in biz for up to 100 people, no problem. High-end Sennheiser microphone on the lecturer, and the vocal-speaking voice sound is outstanding.

      Music Instruction: plug in two pianos or guitars at once, you have an instant music school. Two mics, give vocal lessons. No more lugging around pairs (or more) of amplifiers or PA. Add a small mixer that actually HAS flexibility with more ins/outs, and no doubt this is a serious tool for more advanced recording applications.

      One-man-band: MP3 player into aux in, and split the signal of the double-neck guitar to a pair of floor effects units. Run the 12 string side into a Boss acoustic modeling gadget, and route that output into one of the instrument inputs. Run the 6 string side into a floor multi-effect switch bank, and route that into a second instrument input channel. Hot, mellow, crunch or whatever, nailed it! (Vocals get their own channel as well, and you are in biz for small venues or rehersals.)

      Summary: I rate it a solid 4.75 stars, missing the last 1/2 star only because someone forgot modernisms of USB and Mini in/out. If you can make the AS100D 2.0 model, PLEASE add those essential ingredients!!! Otherwise, recommend people pick up a mixer as a side-bar, just to get the hot signal into other gear (computer mainly).

      This is light years ahead of a mere "acoustic amp." The sound quality of this Marshall trumps numerous other items costing far more, including full mini PA rigs. This IS a PA system, in addition to many other possible applications. Being almost self contained (with a side case of adapter gadgets), there isn't much on the small scale you can't do with it. Worth every penny, particularly when you need to switch gears depending on what day of the week it is.

        Comments about Marshall AS100D 2x8 Acoustic Combo Amp:

        This is my search-stop for a combo amp. The Marshall meets all my expectations. And if I want to go big stage I can XLR through! Super amp! I play an electric acoustic and get the sound I want with this amp. Plenty of punch, power and warmth, and no loss of sound quality when turning the amp way down in a small room. When I add my usual external processor in it just gets sweeter! Getting my guitar sound the way I want it has been really tough to do over the years because I finger pick with a lot of power strumming. I also add a small guitar compressor only because of the extra processor settings. Tweaking the external compressor works and does not seem to compete with the amp's built in limiter as near as I can tell. And I like the amp's FX package... I can add it to both guitar and mic channels or turn it off on the mic only. The 15 watt phantom power does not bother me... if I need it, a simple power supply will get me where I want to be.... not a deal killer! The amp's other features far outweigh the low-wattage phantom power... especially since I don't typically use condenser mics.

          Had to return the first one because of a non-working channel. Musicians Friend was very quick to send me a new one. Replacement works great. Sound is exactly what I expected. Been using in a winery/restaurant in a medium size room with two adjoing rooms. Sound is good in all three with volume below half. My only complaint is the poor owner's manual. Tells you what knobs and buttons are, but not what they do or how to use them. Bass/Treble knobs are self explanatory, but the rest could use some explaining. I'm acoustic only, and this is my first real amp.

            Comments about Marshall AS100D 2x8 Acoustic Combo Amp:

            This amp is amazing to say the least! Yes it is a little heavy, but what do you expect from a Marshall! If it weren't heavy, I would be concerned. I do a single act with some acoustic and some electric music with backing tracks and this amp handles it all at once. I have a Digitech Vocalist Live 3 on my vocals and acoustic for effects and a Digitech RP500 on my electric. The XLR inputs on the back are perfect for my IPod for backing tracks or any other sound source. There are left and right XLR outputs on the back of the amp that I connect two powered speakers to and that's all that you need for a great sounding system. The amp alone is great for small venues, but when you add a couple of powered speakers the amp turns into a mixing board. It's AWSOME!! The only draw back is that it doesn't have individual effects controls for each channel, but if you use processors, which most of us do, you won't need it anyway. I would recommend this amp to anyone wanting to achieve a great sound without spending a ton.

              Comments about Marshall AS100D 2x8 Acoustic Combo Amp:

              Had mine for 3 years.

              Soundwise , it's a great amp, crystal clear reproduction. Also has 3 instrument and 1 AUX channels, which might give you some stage flexibility or work as a single PA system for a 1 voice, 2 strings, 1 drum machine duo. Several effects, phantom power, feedback reducer, and all the other standart features. It has loop, also.

              Now the bad news: it's huge and weights a ton. Seriously, this is havier than my Peavey Delta Blues, which is 100% tube. After a big while, it has hit me between the eyes that this amp would hardly go anywhere because of it's portability issues. If it's not fun to take it to a casual family barbecue,then what's to say about regular coffee shop gigs (keeping in mind that you won't need it in larger venues, because of its own PA)?

              In other words: the purpose of such an amp is to let you play where no sound system is avaiable. But thrust me on this one: this will not be your easiest task with the AS100D as your sidekick. Unless you're a weightlifting olimpic medalist.

              With that in mind, I've shopped around for one of the lightweight models and settled for the new Acoustasonic 100. Doesn't have as many channels, doesn't sound as good, and it's not as loud. But your mate should have his own amp, your regular audience doesn't have absolute ears, and the Fender is loud enough for a PA-less stablishment.

              Overall, the AS100D is Marshall quality to the bone. But its concept has been outdated by the new developments in the industry. It makes no sense to load all that weight into something that's meant to go around.

              But I'd recommend it to whoever has the muscle and the ears to it.

              It would be nice for the effects to be able to applied to only one channel, instead of having two amps. Still, for something like a guitar, or flute (which I play,) it is wonderful. I can get accurate, amplified sound, which is difficult to do. Oh, and a 48mV phantom power would be nice, too. I still have to use a separate preamp.
