Currently the two models offered are the AC601 (with one 6" speaker and a 1" compression driver with custom horn) and the AC101 (with one 10" and a 1" compression driver with custom horn). Although either combo can be used with any acoustic instrument, the AC601 is recommended for guitar and the AC101 is recommended for bass.

"It packs a heavyweight punch without the hernia, the quality of sound is first-rate, and its tonal versatility is presented in a simple, practical package. It's a reasonable prediction that the Markacoustic is set to repeat the success of its bass counterparts."

"The first things we noticed, besides the ultralight weight, were the beautiful look and the top-rate build quality."
"Our test started with the small AC601, which has one 6†speaker. We were immediately impressed by the volume and the beautiful tone of this small cube that weighs just over 8kg. It puts out an incredible amount of sound. Due to the size we expected a lack of low frequency response, but the AC601 reminded us where it comes from: bass sound is the expertise of the manufacturer. We had confirmation of this!"
"The sound is very clear, defined, aggressive and at the same time warm and enveloping, rich at every frequency with the EQ controls at the central position."
"The Markacoustic amplifiers are going up against well-respected competitors in the middle-high segment of the market, but we must say that the competition should not frighten them: these amps play better than many other models produced in foreign countries and they cost less than some of their similar competitors."

"When I picked up the AC601, it felt ridiculously lightweight and I must admit to feeling somewhat skeptical about the degree of tone and punch that could be capable from an amp of this size. This combined with what appeared to be an extremely simple control panel didn’t leave much to the imagination. Yet, when I plugged—what is a particularly average guitar fitted with a bridge transducer—into the 601, the sound immediately came to life. The degree of available tone is quite remarkable, and having not touched the amp settings, this was a good sign. The default settings were significantly cutting frequencies across low, mid and high, resulting in an exceptionally smooth and silky tone. This little beauty has a distinct compressed, yet open tonality that I find extremely appealing. Maybe because of the amp’s ability to produce a very clear sound, and a low tweeter setting being possible, an impressive low hiss sound was achieved... Even with the simple three-way tone controls, loads of extra tones are available to boost across the spectrum, allowing far more extreme sonic results, thus making the AC601 a potent little beast... Considering the size and weight (only 8.8 kg) of the AC601, the amp produces ample volume and punch. Even at the point of feedback there was still more available gain before the clip lights became active... The AC601 excelled in every way I could imagine, sounding really great at every level. Whatever was plugged into it sounded superb, which says that Mark is indeed doing something very right... If you are looking for ultimate sound quality at ridiculously portable and compact proportions, this is the amp for you. It sounds superb, whatever you plug into it."
