-Livingroom-'s review"Great for clean sounds"

Marshall AS50R
50-watt solid-state amp, although the output power is gentler than that of a tube amp. The anti-feedback function isn't easy to adjust. It features a reverb and a chorus, an XLR input for guitarist who sing, as's handy when you're playing on the streets.


Two channels, which isn't very useful, except for the fact that the second one has an xlr input (and I seem to recall it also has an RCA input).

It's great for CLEAN acoustic and electric sounds (distortion is not its thing, not even with a great effect) and it's awesome for picking!


It was great when I played only acoustic sets with my band. Many great acoustic artists use it due to the quality of its clean sounds. It's also a handy online monitor for artists who can't hear a thing onstage.

Effects are discreet and nice, even when pushed to the extremes. The guitar signal is well respected even if it makes everything sound somewhat mids-heavy.


I use it now at home to practice picking. I love its dynamic response and clean sound. Its value for money is not bad, considering that there aren't many acoustic amps on the market. To the question of whether I'd buy it again, I'd have to first ask myself "Do I need it?," considering that you often have monitors and DIs onstage...

xanne's review"Versatile and faithful"

Marshall AS50R

Everything has been said already!

It has an RCA input to connect a music player, which makes it ideal for playbacks

It only lacks a MID control. But for the price...!


It's very easy to use: You plug in and it works!
However, the anti-feedback is a bit more complicated to use without altering the initial sound.

But the rest couldn't be simpler.

A small drawback is that it's really heavy!!!!


I use it for guitar and mic. Or in AUX (yes, yes, it has an AUX input), it's not bad.
The chorus is wonderful and makes sound really crystalline.
I play an Ovation and an Art & Luterie and get a good sound with both.
But be careful with loud guitars (Art & Lutherie on the basses).
The reverb is very good (I don't understand the negative reviews in this respect: I tried the digital version and it's less convincing).

The output power and sound dissipation are great (the angle is large enough for a large auditory).

The sound through the XLR line is awesome, too.


I play regularly in my basement, outdoors and in quite large venues, and it's impeccable.
As a beginner, I don't regret my purchase and would definitely choose the same product again (except maybe for the backaches due to the weight!).
Ideal for beginners who want to skip the "bad sound" phase. Faithful among the faithful.

MGR/Jim M's review"Marshall AS50R Acoustic Combo Amp"

Marshall AS50R
I recently purchased this amp at a local dealer in Evans, GA. the amp cost ~$370.

I like the sound, style, & accessories available on the amp. It provides plenty of power 50W for playing at home, school gym, church, cafe, or bar/grill/lounge. It provides a clean, crisp sound with reverb & chorus effects. It has many optional abilities that allows this amp to be used for many reasons.

I have not found anything I do not like about the amp to date. However, Marshall was slow about shipping it to my dealer & Marshall accessories are slow to obtain (e.g., footswitch) as I am still waiting on the footswitch I ordered from them two months ago. I guess the quality makes up for the delivery. As they say "good things come in time".

It is very well made & pleasing to the ear & eye.

This is a well made acoustic combo amp with multiple uses for a resonable price. It is easy to use & can serve for both a guitar amp & PA combined.

MGR/Ronguitars, luthier.'s review"Marshall AS50R Acoustic Amplifier"

Marshall AS50R
I bought this amp from Elderly Instruments for $379 2 years ago.

I enjoy the clean, pure sound of the speakers + tweeter configuration. The chorus is excellent, the reverb passable. Plenty of power for a large room. The notch filter has come in handy and worked well when it was needed. But the overall quality, and cofiguration of the controls on the amp is great.

An effects loop would be nice.

The construction of the cabinet is A-1, as well as the knob controls and faceplate.

I would not hesitate to purchase this amp again. I've loaned it out a couple of times too, and it always comes back with rave reviews from the borrower.
