Rumble Studio 40 : Great bass amp

I am using this amp for both guitar and bass practice. It is an amazing amp to work with.

Even if it is loud enough to make things on the wall to start shaking, it keeps its sound clarity when the volume is rolled down.

The tweeter option is great when playing other instruments through this amp.

Even though some presets are decent, my advice would be to get used to dialing in your own tone as quickly as possible.

The menu interface is very easy to navigate.

It does not send sound to the PC via USB, which was a surprise for me, but the other sound output options are a good workaround.

I really like touching the amp when setting up presets, so I can't say anything objective about the phone interface.
