 Hello, I'm Christian Hermansen and I'm here today with a Sonnet 60 from Blackstar. There are two preamps, one for your guitar and one for your voice. Each preamp has a set of independent rotary controls, so you can EQ your guitar and your vocals separately. There is also a shape button that applies a preset EQ, on the Sonnet 60 it cuts the mids and boosts the highs and lows. In addition to this, there is a brilliance control, with which you can add or take away up to 6 decibels at 16 kHz. So if your guitar is not sounding quite exciting enough, you can add a bit of that sizzle on top. Or in contrast, if it's sounding too harsh, you can turn that down a little bit to mellow it out.
