So the update to version 2 for the Boss GT-100 has been released. It is a relatively straight forward procedure to update the unit, and I take my hat off to Roland for continuing to support the GT-100 and not write it off for the sake of producing a new 'flagship' unit, here is a little review of my first thoughts since the update. There is also tough competition from Line 6 (now acquired by Yamaha, which should be interesting), Digitech and of course the high end and very expensive Fractal AXE-FX and Kempler Profiler, so this might explain why Roland are keen to develop the unit given the R & D time taken to get another product to market. Whilst the GT-100 doesn't compete with the AXE or Kempler, it is great to see some very careful and well thought out additions to the Roland. For my full review of GT-100 version one, please click here.The headline features of the GT-100 Version 2.0 update, include the addition on Boss' new Multidimensional Processing MDP effects, such as the Tera Echo and Multi Overtone. I am particular looking forward to using this as part of my duo (North & South), as it adds fills out the sound. There is also an acoustic guitar simulator, I have only played with this for a short time and it seems to work, trying it live will be the test of this. There is also an improved rotary effect, which again is useful for creating organ sounds when live looping.I am particularly interested in the guitar to midi function, this is very useful for me. Whilst I have the Roland GR-55, having the GK-2 is a pain (okay it's not really a pain it is a fantastic piece of technology, but the caution me never really trusts it for a live gigging situation). The guitar to midi is only monophonic, but it is great for getting lines down into a computer, and also for transcribing songs. Again, I haven't really tested this, but I will follow up when I do.There are a couple of new amp models, but I tend to use the Natural Clean now for most of my recording because it sounds really good, this plus a different stomp box in front gets the the tones I like. There is no information on line, but one of my criticisms of the GT-100 was the speaker simulation, and I can't really tell if this has been updated, it doesn't sound like it to be honest.Finally, Roland have produced a Mac editor that actually seems to work and looks like it has come from this century! The Boss Tone Studio is a graphical interface for PC and MAC and it works so much better than the other attempts out there.To sum up, well done Roland, fix the speaker sims, power supply and XLR output and this will be one hell of an awesome toolEnjoyPeaceNeil
