Demonfx TONE MALLET Bass PreAmp Boost/OD with DI Hint... Nice for Guitar too! This is the Demonfx Tone Mallet that gets it's inspiration from the Tone Hammer which has been a favorite of many a player. Designed for Bass-this one has some shaping and sculpting along with some nice Gain punch if desired. Features and Functions: A. Top Panel GAIN: Controls input sensitivity level TREBLE: +/- 18 dB @ 4 kHz BASS: +/- 18 dB @ 40 Hz MID FREQ: 180 Hz to 1 kHz MID: +/- 17 dB of cut or boost MASTER: Controls output level ENGAGE FOOTSWITCH: toggles between on/bypass (blue LED indicates on) AGS FOOTSWITCH: toggles AGS on/off (red LED indicates on) Adaptive Gain Shaping (AGS) -AGS changes the gain structure and EQ interactively with the gain knob position. This produces a "vintage voiced " EQ that adapts as you adjust the gain knob. The lower the gainknob setting, the "flatter" the EQ applied. The higher you set the gain knob, the moresaturated the gain structure becomes, and the more the bass is tightened and the treblesmoothed. -AGS provides a continuously variable boost depending on the position of the gainknob. The higher the gain setting, the more boost you will get. -The AGS circuitry surrounds the midrange controls, enabling you to get a huge varietyof tonal characteristics by simply adjusting the gain and midrange controls. What this gives you is a flexible control to get a wide range of tonal colors. -With the Gain knob set from 7 o'clock to 11 o'clock, AGS gives up to 12dB of cleanboost with warm, glassy, vintage EQ.-With the Gain knob set from 11 o'clock to 1 o'clock, AGS gives up to 15dB boost, with alittle vintage growl as the EQ tightens up the bass. -With the Gain set from 1 o'clock to maximum, AGS gives up to 16dB boost full of warm, vintage saturation. The EQ tightens up the bass even more for a smoother response. B. Side Panel IN: OE? input, 1mega Ohm input impedance. DC IN: This is a standard 2.1mm DC jack. The center terminal polarity is negative. Compatible with 9-18 VDC regulated power supplies. PRE/POST: This will place the direct signal either pre or post EQ. Pre: Your signal goes to the D.I. XLR output before your Gain, AGS and EQ settings Post: Gain, AGS, EQ and Master settings will be sent to the D.I. XLR output jack. DI: balanced output, maximum output level 8 VRMS. GND/LIFT: If there is a hum when using the D.I, there may be a ground loop. In many cases, pushing in the Ground/Lift button can fix this problem. OUT: OE? output, maximum output level 4 VRMS
