The Siege Engine II is a powerful bass weapon that features a 5 band EQ and overdrive section that allows you to carefully tailor the gain and tone at different frequencies.
• Pre Gain: The high impedance jfet input amp feeds directly into a Pre Gain control that can push the overdrive section harder or lighter as desired. It’s a quick way to alter the overall aggression and when pushed hard can introduce some harmonics on its own.
• Overdrive: In the overdrive section the signal is split into Bass, Lo Mid, Mid, Hi Mid and Treble frequency bands. Each band has a Level control and it’s own Drive control. All the bands are summed back together to form a harmonically rich tone that still maintains the integrity of all the notes you're playing.
• Footswitches: There is one footswitch for the True Bypass and another to switch the Overdrive section on or off.
Overdrive Section
Engage the entire Overdrive section with the Overdrive stomp switch. In the overdrive section the instrument signal is split into Bass, Lo Mid, Mid, Hi Mid and Treble frequency bands.
Bass, Lo Mid, Mid, Hi Mid and Treble: Sets the output level of each of these frequency bands. These frequency bands also have individual Drive controls which sets how much overdrive is applied to that particular frequency range.
Volume: All the bands are then summed back together to form a harmonically rich tone that still maintains the integrity of all the notes you're playing with the Overdrive’s output level being set by the Volume control.
Hi Cut: The Hi Cut control works on the summed overdrive signal to tame the possibly huge amounts of higher harmonics generated by mixing all the overdrives together.
Master: The Master volume sets the output level of the pedal whether the Overdrive is on or not.
DC Power In: The Siege Engine II requires a DC input from 9 to 18 volts, with a current of 220mA at 9 volts, 170mA at 12volts, or 120mA at 18 volts. Internally the voltage is converted to +/- 12 volt bipolar power rails for increased headroom and fidelity.
Recommended Settings
As a starting point we recommend setting all the overdrive section's bands to noon and the drives to the same or a consistent lower level.
From there you can experiment with adjusting the pre gain to quickly add or subtract the total gain, or individually adjust the overdrive channels. To hear what each overdrive channel sounds like individually you will have to turn all the channel's levels down to 0 and then bring one up by itself.
