Very good topic at the right moment.
Mainly I was using - nice and bassy Hartke vx410 + HA2500 head, VOX AD50VT guitar amp and Wharfedale SVP-15P monitors. After years and overloads of sound because "the louder the better to rehearse in" Wharfedale monitors went silent and, well, RIP. I'm still thinking whether there is a need for monitors or no, but it seems just like a rather expensive addition to equipment if playing just noise.
