550 BlueGrass (Guitar / Bass)

1 399,00 

For bassists and guitarists…

The 550 BlueGrass is an incredibly simple multi-instrument amp for bassists and guitarists who want a little more than 35w.

Bassists will find the precise and round sound of a tube amp, and above all, it is transportable.

As for guitarists, they will as well find their account with a dominant clean to become an excellent platform for pedals, passing by dynamic effects (compression, distortion…) or / and by temporal effects (reverb, delay, chorus…). The vintage crunch sound will also be present with the possibility to control it with the gain knob.

Multi-instrument ? Harmonists and keyboardists of good Rhodes will be won over, for sure!
