GPA-400 : A Genuine surprise

Check my quick review at : a bit more in depth though :

This is an epic amp and especially for the money , its built like a tank and has a reasonable tone although not as bright or punchy as its obvious competitors , as far as what this is up against the Rocktron Velocity series is obviously the number one and having owned both now I can see why , although this has plastic knobs and lacks the finesse construction wise of the rocktron it does a reasonable job trying to emulate the capabilities having almost identical specs .

the one place where this doesn't compare is in the actually tonality if the amp itself , it has the high and low shape controls but it lacks a certain brightness and full bottom end that the rocktron shines at , although the big problem here is that after years of use this has survived and after 6 replacements the Rocktron just broke down consistently.

In conclusion after road testing both units I have to say that this is more than worth the money and with some tweaking I got a crushing sound from it , so if your using in particular a preamp processor of the likes of the Kemper/AxeFx/Helix then this is a great value and easy to use unit that is small but does get hot so leave some breathing space lol , grab a bargain .
