I've been using this almost daily since I got one. The drive channel is especially lovely. This thing is packed with features and it takes time to get familiar with everything.
Basically, you have four sounds per channel:
- clean
- compressor
- reverb
- chorus
... you can change the parameter of each sound. For example, you can change the rate and depth of the chorus. And the reverb is especially good!!
You'll get decent training time from a set of two AAA's.
