Hello, I have had a standard M01 for around two months now and thought I would share my thoughts for anyone else looking to make a purchase. A jam buddy also has an M01 antique, so we often play the two side by side. I believe both are 2021 or 2020 models. All in all both guitars are good value for money and it seems that you get what you pay for with the Altamira range. I think they are the best value for money when compared to other Asian guitars. The differences between the models are not really pros and cons, but kind of go either way depending on personal preference. Each now has a Dupont bridge which is a noticeable improvement over the stock one.
The standard M01 has a poly finish that dampens the highs but is very durable, while the antique has more highs and 'pop' that is quite easy to scratch, revealing the lighter wood underneath (which is a cool effect if you like that). In comparison the standard sounds more mellow and rounded, while the antique is sharper and more present.
The standard seems to have a slightly thinner neck profile than the antique that I notice every time I switch, but I have not measured it to confirm.
Oddly, the standard came with a dull tailpiece that was already tarnished and is continuing to tarnish quickly, while the antique has a shiny new looking one.
Both have bad tuners that go loose when detuning, so if you are a bit sharp you often have to go way below the desired pitch then back up to it to get the tension. I am looking to replace mine.
The setup was really good. All the frets and nice, smooth and level, but the truss rod needs adjusting if the guitar is moving through different climates. No big deal with that. If you are going to get a case for it, I would definitely recommend the Altamira case over the Saga Gitane case. It feels of higher quality and isn't such a tight fit.
Note: the low E string bridge hole is not big enough for Gallis, with the ball end sticking out about 1cm due to the string diameter. Once it's in there tight, it's not a problem for tuning, just inelegant. I will use loop Argentines in the future, anyway.
The process of ordering and shipping was not the best. We live in New Zealand so we deal with the exchange rate, shipping fees and just generally high cost of living, so these guitars are relatively expensive items. I kind of feel like I am bothering Djangobooks every time I send them messages because I don't often get much of a reply. I am still going to buy from here because the service is good enough and we are lucky to have access to such a wide range of GJ products at all I guess.
Thanks for reading. Photos to come...
