I´ve realized that there were some factory presets with the Grahic EQ in Amplitube 3 which don´t show up in Amplitube 4.
So I´ve made some Amplitube 3 presets with these Graphic EQ module presets and imported them into Amplitube 4. Now I´m able to use them in Amplitube 4.
In my opinion using these Graphic EQ factory presets impoves the sound in Amplitube alot.
For example take the "Bottom & Prescence" and " Bright & Fat" Graphic EQ presets and tweak only the amps tone contols (if needed) and see how the sound improves.
The amp models in Amplitube sounds great but with the Graphic EQ they sound even better.
I´ve tried this with the 5150 and Marhall typ amps and so far and I like the results very much.
Try it by yourself and post your opinions.
I have posted some presets on preset exchange for you guys who don´t own Amplitube 3 so you can transfer these presets into Amplitube 4.
