Well. The Digitech Screamin' Blues is a good pedal, rather quiet, at least till 70% of the gain. It provides 2 flexible Outputs, one for the Amp and one for Mixer. Obviously, with 4 simple controls, Level, Low, High and Gain, it is very easy to use. The Screamin' Blues is robust, like any other Digitech pedal, and it costs only 53 Euros! We cannot ask more. Really. The tone of the Screamin' Blues is bright and clear, rather cutting. It adds clarity to the sound, you can hear it as soon as you use it. More. It adds also Volume, but without changing the tone of the original sound. Obviously, if you send the Screamin' Blues in an all-tube amp you will be disappointed. This is sure. This Digitech cannot make miracles for only 53 Euros! So, i believe that this Digitech is a good pedal if you get a solid state amp. In this situation it will boost your sound and it will add dynamics and Volume with a good result. This is, i think, the best setup for the Screamin' Blues. The 2 outputs add a bit of flexibility. The mixer output provides a speaker emulator of good quality. A good pedal from Digitech, this Screamin' Blues. And very, very cheap.
