The HT Stage 100 guitar amp uses a quartet of selected EL34 power valves to deliver 100W of British dynamics with 3 channels delivering 6 modes for amazing tonal versatility.
 The patented ISF control works with the Bass, Middle and Treble controls to give you access to infinite new sound possibilities from the USA to the UK and everywhere in-between. This fully interactive control allows you to infinitely adjust the response of the tone control network between any of the traditional voicings. In this way you can design your own sound and truly find the sound in your head.
 Overdrive 1, Overdrive 2 and Clean channels are available on the HT Stage 100. These are all fully footswitchable from the footswitch provided.
 The HT Stage 100's Reverb control sets the overall level of the reverb effect. With the control fully counter clockwise there will be no reverb. Turning the control clockwise will increase the amount of reverb.
 The Tone control allows adjustment of the balance between treble and bass frequencies within the sound. At low settings (counter clockwise) the sound will be warmer and darker in character. As the Tone control is rotated clockwise the sound will become brighter.
 In the out position Overdrive 1 has a 'classic' overdrive voicing. With the switch in the in position the Overdrive 1 has a more 'modern' voicing, with a greater bass response and a looser more aggressive sound from reduced power amplifier damping. With the Voice switch in the out position, Overdrive 2 has a 'classic' overdrive voicing similar to Overdrive 1, but with a little more gain. When the switch is in, mid-band gain is applied to give the overdrive sound more 'body' and a smoother overdrive characteristic. 
 The HT Stage 100 has a fully specified speaker emulated output which further enhances the studio credentials and allows any guitarist to get amazing valve tone straight to tape or disk.
