It’s hard to believe how much you can fit into an amp in a compact lunchbox format! Twenty tube watts can still be mighty powerful, so with the Powersoak, the output power can be reduced to 1 Watt, or the speaker can be completely deactivated - perfect for practicing with headphones or for recording sessions late at night. We’ve given the Ironball a frequency-corrected line output for this. The Master Volume Boost (M.V.B.) provides a footswitchable boost of the master volume, meaning you have a second master volume at your disposal. A Presence control and built-in reverb make this sound package ready, no matter whether you’re headed to the stage or the studio!
