U-Sound Crunch Of Clubs - All Tube Preamp



The first floor preamp of the new "Preferences" series. The unit is pimped with four 6S7B tubes that were used in space and military technologies in 60's and 70's. Todays these tubes usually find their application in the high end audiophile systems. The tone of this unit is primarily a bright vintage sound that works perfectly for blues, classic rock, rockabilly and fusion. Along with the additional units (like overdrive, compression, distortion and other pedals) the power and flexibility of this preamp becomes unlimited! The sound sample (Sample 4) below is the example of using the preamp with a "Doodle Doo" pedal. The result is a modern agressive guitar tone. The two channels of "Crunch Of Clubs" have a mutual 3-band EQ, "Bright" switch and the separate "Gain" and "Volume" controls. The channels are toggled with the A/B footswitch. In case the pedal is used in a chain of effects it can be turned off with "ON/OFF" button when necessary. The pedal has the regular "Input" and "Output" but also the speaker-simulation output designed for transmitting the signal right to the console, or recording in line. The adapter is a custom designed separate unit giving a stable power supply. It connects to the pedal via XLR input.
