1)Lead—The Lead footswitch selects between Rhythm and Lead Chan- nels on the amplifier, regardless of the setting of the channel selector switch on the front panel. If the LEAD word is backlit, then the Lead channel is active. If the LEAD word is unlit, then the Rhythm channel is active.
2)Boost—The Boost footswitch selects the adjustable volume boost as determined on the back of the Defender amplifier. This gives up to 10dB of “master” volume boost and the tone is optimized for solos. It affects either channel, and when the Boost is backlit, the Volume Boost control on the amp is functional.
3)Effect—The Effect footswitch activates the Reverb on the V50, and is switch assignable for Reverb or Tremolo on the V100. When Effect is backlit, the appropriate effect is activated.
Emergency Mono Cable Use: If the stereo cable or footswitch were dam- aged, a regular instrument amp cable or single button footswitch can be used to provide limited capability. If a mono cable were used, the Chan- nel Selection(Lead) button would select between Rhythm and Lead, but it would not illuminate. Also, the Boost function would be disabled, and on the V50, the Reverb would also be disabled. On the V100, either Reverb or Tremolo could still be used since selecting the other with the footswitch assign button would disable it.
