The Fuchs Viper 100 watt head is a high end boutique amplifier from Fuchs Audio. It includes a wonderful and diverse clean channel that covers chimey clean tones, all the way up to a dirty rock growl, as well as warm overdriven tones in between. The high gain channel has massive amount of distortion on tap, perfect for modern scooped metal tones. The "thrust" control lets you tweak the amount of low-end thump in your sound, while the "presence" control shapes your tone.To change between high and low gain channels without the footswitch, pull out the high tone knob in the low gain EQ section.Features:4 - 6550 Power Tubes6 - 12AX7 Preamp TubesFX Loop with Bypass Switch4 Ohm, 8 Ohm, and 16 Ohm Individual Speaker OutputsSeparate EQ sections for each channelMaster Controls for each channelThrust + Presence ControlsFuchs channel footswitchPower cableThis amp sounds wonderful, but is simply too loud for my current living situations. *NOTE: This amp does not come with a user manual*If you have any questions, please feel free to ask.
