 Hello, I'm Christian Hermansen, and I'm here today with a Sonnet 60 from Blackstar. The 60 watt combo is designed specifically with acoustic guitarists in mind. The custom designed 6.5 inch speaker and high frequency tweeter faithfully amplify your voice and your guitar. There are two preamps. One for your guitar and one for your voice. They both contain dynamics control processing. Now this helps to reduce harshness that you'll sometimes find in other guitar amps by smoothing out the peaks and therefore creating more headroom within the amp. The Sonnet 60 has two inputs, one of them a jack, the second one a jack or XLR. If you choose to put in an XLR, the signal goes through an additional low impedance stage giving you extra gain for mic level signals. Or if a jack is inserted, the signal skips this stage and goes straight into the preamp.
