Ironball Full Tube Guitar Amplifier Operator´s Manual Please, first read this manual carefully!
Welcome to the Ironball guitar amplifier. This compact, fully tube-driven amp delivers "to die for" tone in a phenomenally portable package! This head, is the perfect sidekick for playing small gigs, recording in studios, and practicing at lower volumes without sacrificing tone.
Lead Gain: Gain control for the Lead Channel. This Control knob determines input sensitivity when the Lead is active. Use it to dial in the desired amount of preamp saturation level. A tip from the designer: Sometimes a touch of dirt is all you need for snarling rock riffs and gritty rhythm work. If that sounds sweet to you, deactivate the Gain Boost (10) and turn the Lead Gain knob to the left of the 12 o'clock position.

21 Headphones: Connect stereo headphones rated for 8 to 32 ohms to this stereo jack. Alternatively, you can connect two hi-fi speakers with 8 ohms each to this output. Note: The signal routed to the headphones amp is tapped post power amp at the 8-ohm output and is processed by the frequency compensation filter in the Balanced Line Output circuit. The signals patched out through the headphones amp's two outputs are identical. This signal is only available when the power amp is on.

Handling and Care * Keep the amp safe from hard knocks and shocks. Tubes are fragile and tend to suffer when exposed to mechanical stress! * Let the amp cool down before you transport it. Ten minutes or so will spare the tubes. * Tubes take some 20 seconds to warm up after you switch the power on, and about two to three minutes before they are able to pump out full power. Make a habit of giving your amp plenty of time to get toasty and flipping the Standby switch for short breaks.
Troubleshooting * The amp does not power-up after you have switched the power on; the Channel & Gain Boost switching functions do not react, i.e. the corresponding control LED's do not indicate an active function; moreover no sound is emanating from the connected speaker. -> Is the mains cord connected to the receptacle / live power source? -> Is the power cable you are using intact? Try another equal mains cable.
