You have a ton of options, especially on what amps you added, if any, to Amplitube. I will assume that you only have what came with the program.

Here are some excellent tube amp choices. They are as follows:

1-default-American Tube Clean
2-default - Amplitube Legacy-Complete rigs-Clean-Ambience SR
3-default- Amplitube Legacy-Jazz Amp 120

Set the tone, gain, volume and reverb to your preference. These will vary depending on what guitar, guitar's pick up, volume and tone controls you input to Amplitube.

IK has some free DLs available and one is very similar to the Roland 120 jazz chorus amp. This is also excellent for jazz guitars, as is the other Roland 120 emulation mentioned above.

If you purchase the Fender amps package you will have a ton of options.

If you are looking for solid state amps there are a number of them in Default-Legacy Amps.

There are many options for you to choose but most presets will need a little tweaking. I have found many presets have more bass than I need so I have to cut back on them. Some also have the gain control to high for my taste. YMMV

Good luck and I hope this helps.
