Rockhill 4 string same riff through various amps on favourite settings (within reason)
To show the differnces between amps hope this helps you.
Micro cube,Fender mustang, Bugera rat,calvin tweed...
in lowest price order
40xl has a looper and channel switching
the 30 bass coube sounds great with the odd thing and a tube driver
The vox Vt 30 i had to fix as it packed up the first time I used it so bears a grudge
The Cube may be easier to tour with and probably reliable..
Me I like the 3d sound of valves,
Let me know what you think
Bugera rat and spider 3 were left off this test as the Bugamp would probably win and the spider 3 loose (only good for metal).
Hope this helps would be interested in your comments...
Sorry all you scientists... I'm not one!
