It is a very good amplifier. Super clear sound, very clear. It brings out the bass sound as is, but with the growl of the preamp valve, a joy. If you have a good bass, this is your amplifier, but if what you want is to improve the sound of the bass, no. The only drawback it has is the few options to change the sound, but sometimes that is an advantage, because it simplifies things a lot. I use it with a Behringer BDI21 pedal and the truth is that the change is noticeable. I recommend it.
