Designed for electric bass players, the Soundblox 2 OFD Bass microModeler from Source Audio is an effects pedal with 12 different overdrive, fuzz, and distortion sounds, all in one compact enclosure. It digitally replicates the tonal characteristics of several revered stompboxes, and includes a few original algorithms, along with providing controls for drive, tone, and more. Quite usable for bass players is the mix knob, which can either dial clean tone into the signal, or dial in what Source Audio calls "High Cut Clean Tone"—signal EQ'd to deliver clean low end and nothing else. This comes in handy for rounding out particularly aggressive distortions.
With these controls, as well as a three-band equalizer and an onboard noise gate, you’ll be able to elicit a wide array of tonal possibilities, all of which you can store within two presets. You can recall these presets by clicking either footswitch, and saving a preset is as easy as pressing a footswitch and holding it down. Multiple methods for external controls are possible, as outlined in the features section.
This pedal uses a 56-bit digital signal path to achieve its emulative effects, though its converters operate in industry-standard 24-bit on the A/D and D/A side. While the unit utilizes digital architecture, its bypass is analog, ensuring your signal is fully routed around the DSP with no degradation. Included with the pedal is a 9 VDC power supply.

Controls at a Glance
DRIVE Knob: This adjusts the amount of distortion applied to the signal.
MIX Knob: This adjusts the level of clean signal added to the mix; you can choose between standard clean tone or clean tone EQ'd to provide low-end information only. This can help retain sonic purity to the bottom end of the frequency spectrum, allowing the bass to carry on its essential function in the band while still growling away in distorted tones.
TONE Knob: This cuts or boosts the selected TONE SHAPE (treble, mid, and bass).
OUTPUT Knob: This adjusts the output level of the final signal.
NOISE GATE Button: This selects the noise gate threshold level. This also selects the External Control mode.
TONE SHAPE Button: This selects which frequency range will be adjusted by the TONE knob.
FOOTSWITCHES: Both footswitches are used to enable/disable presets. Press and hold to save an edited preset.
SMOOTH TUBE: Based on Mesa/Boogie preamp distortion.
POWER STAGE: Inspired by the Fulltone Distortion Pro.
CRUNCH TUBE: Not an emulation, but an aggressive tube distortion of Source Audio’s design.
TS9000: Based on the Ibanez Tube Screamer, featuring a lot of mid boost.
BIG PI: Based on an Electro-Harmonix Big Muff Pi of indeterminate model specification.
EL RATON: Based on the ProCo Rat.
FUZZ FAÇADE: Emulation of the Dallas Arbiter Fuzz Face.
BENDER: Modeled on the Tone Bender MK II.
METAL: Not an emulation, but a metal distortion with plenty of highs and lows, designed by Source Audio.
OCTAVE FUZZ: A full-wave rectifier mimicking the Octavia (Please note: try turning down the high-frequency control knob on your bass to bring out the higher octave).
GATED FUZZ: A wild, digital sounding fuzz held back by a sensitive noise gate. Similar to a ZVex Woolly Mammoth.
