Lay siege to your enemies with the Siege Engine II Bass Pre-Amp. The Siege Engine II is a powerful bass weapon with a TON of overdrive and massive flexibility and outputs. The pre amp features a 5 band EQ and overdrive section that allows you to carefully tailor the gain and tone at different frequencies.
Each frequency band of the ovedrive section features a true clean signal blended with jfet overdrive for a total of 15 hand tested and selected jfet transistors in all.
100% analog.
Use as a pedal with true bypass in your effects chain, feed a power amp directly, as well as sending DI outs for recording or live mixing.
• Input and Pre Gain: The high impedance jfet input amp feeds directly into a Pre Gain control that can be pushed hard to introduce some drive, which in turn pushes the overdrive section harder or lighter. It’s a quick way to alter the overall aggression.
• Overdrive Section: 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.
• 4 footswitches: Bypass, Mute, Overdrive, and Effects Loop, to enable full control over all lines of attack.
• Master Outputs: There are two master outputs, both controlled by the Master Volume and Bass and Treble shelf EQs. One is a high level output for feeding power amplifiers and the other is instrument level to send to bass amps or other effects chains.
• Line Outputs: Balanced DI XLR and unbalanced 1/4” jacks to connect to PA, mixing consoles, recording gear or other amplifiers.
• Headphone Output: Connect headphones to use the amp for practice with an aux input to connect to outside music sources.
• Tuner Output: Hit the Mute foot switch and the dry tuner output stays on for silent tuning in live settings.
• Effects Loop: The switchable effects loop has a Send control to set the level of the send output which can get a little too hot after coming out of the Overdrive section.
• DC Power: Requires 9 to 18 volts DC with 420mA of current, like most pedal power supplies.
