The Obstructures x EAE Bass Driver completes a trifecta of neo-brutalist gain devices executed with precision and brawn. Built upon an homage to a beloved vintage Canadian bass amplifier, the Bass Driver delivers solid state noise rock thunder with key augmentations for the modern bassist.
With a gain control spanning a 50dB range, the Bass Driver can be restrained or rowdy. The tone controls are designed to emphasize the natural attack of a picked bass while also provisioning for down-tuned modernism. Critically, it achieves deep low frequency extension without the unnatural, disconnected feel of a traditional clean blend. In addition we included an internally switchable notch filter, useful for tailoring the midrange response to work either in front of an amplifier or as a dedicated preamp with a power amp or DI.
Please note: the 0xEAE Bass Driver is the third and final installment of this collaborative form factor. While this iteration will be produced in a finite quantity, we intend to manufacture this circuit in a new form at a later date.
Specifications
Bypass: Soft-touch relay switching with op amp buffered bypass.
Input impedance @ 1 kHz: 2.2MΩ
Output impedance @ 1 kHz: <1kΩ
Power: 9V DC, center negative, <65mA current at idle. We recommend a regulated, isolated power supply rated for 200 mA minimum. The PSU input is protected against reverse polarity and over-voltage. Our pedals do not accept batteries.
Controls
Volume - overall volume level, capable of extremely high output
Drive - signal gain, from clean to moderate to extreme. Approximately 50dB maximum passband gain.
Bass - post-clipping low frequency shelf boost, up to +14db at 100Hz and below
Attack - adjusts frequencies above 1kHz, tailors the overall clipping response and sharpness of pick attack
Notch (internal switch) - use to activate a notch filter centered at 750Hz. Disabled by default, but can be useful for ampless setups or when running direct into a power amp.
Footswitch: Effect activator.
Dimensions: 6.75” x 3.5” x 2”
Weight: 1.5 lbs
