Marshall AS100D 2x8 Acoustic Combo Amp  

This amp would be so much better if they would have added ONE more knob; an effects knob on the vocal channel. Not being able to select seperate effects for each channel and having to have one effect spread across three channels makes me want to return this amp. Otherwise, it is a very good amp.

Expensive, but I believe it is worth the extra money for its quality and versatility.

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.

First of all, I was apprehensive to buy a used amp, but thanks to the rating of mint condition and Musician's Friend,  it arrived as good as a new one.  Very Pleased.  It looked like just an open box.

I do solo gigs and was using a Music Man 112RD for my acoustic (Yari Alverez DY75) with a LR Bagg passive undersaddle pickup.  The sound was pretty good, but was loosing the warmth and natural sound of my acoustic, even when running the guitar thru my PA.  Well I hooked up the Marshall AS100D and could not believe the sound it was producing for my acoustic.  It was natural, full, and plenty of headroom.  It took my acoustic sound to a whole new level.  I have now used 3 times in a professional setting.

I tried my original 1966 Gretsch Chet Atkins Tennessean thru the Marshall and I have to admit it was just ok, but I have been spoiled by the tube amp for the Gretsch.  After all, the Marshall's for the acoustic, but in a pinch, I could use the Gretsch.

Another thing worth mentioning,  I do some small coffee shop gigs and all I need is the Marshall, my Beta 58 Shure mic, guitar, and I am set.  The amp is plenty adequate to produce a quality vocal sound.

The digital effects are very good....for guitar and vocal.

Bottom line... I highly recommend this Marshall AS100D

Highly recommend the Marshall AS100D amp.

i use a martin swomgt with an L.R. baggs element pickup installed in it, this amp brings out the true color of your guitars sound and can be dialed in to fit just about any gig your going to have.from coffee house to a large bar or a large amphtheatre.it can hook up to a P.A . system for larger venues if needed.i cannot recommend this amp enough to anyone looking for fabulous clean tone that perfectly represents your instruments true sound or use a bunch of great effects bulit in, it is so versitile i can use my 12 string 67 fender villager, a banjo, and even more impressive my telecaster, you can get some really sweet clean tones with the tele and this amp its not a one trick pony.this amp is a anti-feedback king! with tons of different anti feedback features and we all know how much of a pain in the neck feedback can be in a live performance. the mic sounds great also, and yes you can get effects on your gitar but no effects on vocals{some other reviewers complained about how you couldnt} but you can and vocals sound great!

very high quality and a real classy look with brownish red leather outter and gold trim around the speakers. will last a long time, superior marshall quality and very customizable sound and super versitile, one amp for my gigs now.

good value. you 100% get what you pay for!

this is the amp you want,ive tried the fender sfx II the fishmans the p.a systems, and for the money this is the one.it can do it all very very well!

I just purchased the AS100D, and it is an awesome sounding amp.  It's also nice to have three instrument/mic channels.  But I do have two complaints.  First is the phantom power.  It's only 15 volts where most condensor mics need 48 volts for operation & optimum performance.  So you either have to run a separate phantom power supply, or a vocal processor w/ 48 volt phantom power capabilty should you use condensor mics for anything.  The second thing is the on-board digital effects.  They are not assignable, and apply across all channels. Whatever effect(s) you put on your instrument will also be applied to your vocals.  So while it is a great multi-channel amp...you will need to buy a couple of other pieces to have total control over the sound.  I just find it hard to believe Marshall wouldn't at least include 48 volts of phantom power instead of a measly 15, and an effects swith for each channel on an otherwise fine piece of equipment.

Though I have a couple of feature related issues, this is a very high quality amp.

For the money, nobody else touches it.

If it wasn't for the lack of adequate phantom power as explained above, I'd go with a 9 here even with unassignable effects.  I'd even go 10 if it had both adequate phantom power, and assignable effects,
