Overview: A Modern Take on Stereo Delay

The Old Blood Noise Endeavors Black Fountain Stereo Delay SL enters the market as a feature-loaded delay pedal designed for guitarists and synth players seeking depth and flexibility. Distinct for its stereo operation, MIDI expandability, and comprehensive hands-on controls, it retails at $341 and is handmade in the United States. This unit builds on OBNE's reputation for unique atmospheres, now with true stereo architecture and an increased focus on integration within complex modern rigs.

Stereo Architecture and Connections

The Black Fountain Stereo Delay SL provides stereo input and output via a single 6.3 mm (quarter-inch) stereo jack for each, supporting conventional mono through to mono-in-stereo-out settings. This design offers a notable advantage for dual-amp setups or stereo synth chains. Routing flexibility is improved further thanks to both buffered trails and true bypass modes, switchable to suit any preference for signal preservation or effect spillover during pedal disengagement.

For external control, expression control and full MIDI implementation across all parameters are present, accessed through dedicated 6.3 mm and 3.5 mm stereo jacks. The option for USB-C connectivity suggests future-proofing for firmware updates and digital integration. Power comes via a standard 9V DC barrel connector (center-negative), though power supply is not included and current draw registers at 350 mA, which is moderate but mandates a robust pedalboard supply.

Hands-On Controls and Sound Sculpting

The top panel features an array of controls: Rate and Depth modulate oscillation parameters, letting users build subtle movement or wild time-based pitch effects. Tone shapes the repeats; Grit introduces analog-style saturation and breakup, a standout feature among digital delays. Independent time controls for left and right channels foster complex, bouncing stereo fields; Feedback, Wet, Dry, and Space knobs allow for nuanced balancing between direct and affected signals alongside stereo ambiance.

Preset management is straightforward with a dedicated push button, and onboard indicators for bypass and tap/aux status provide clear visual feedback. Tap tempo (via footswitch or MIDI) and onboard preset storage further accommodate live, studio, or creative home setups.

User Impressions from the Field

  • Immediate Appeal: Players report instant engagement, noting immediate satisfaction across both guitar and synthesizer platforms. The pedal's ability to sculpt vast soundscapes without extensive menu-diving receives special mention.
  • Grit Control: The presence of an independent Grit knob stands out. Unlike many digital delays that deliver pristine echoes, this function allows users to infuse repeats with real analog-inspired texture, something testers find themselves missing on other devices once tried.
  • Ergonomics Issue: The only recurring critique relates to the angled rear panel; as a result, patch cables plugged into the back may stick up more than some would like, depending on board layout.
  • Board Integration: On multiple accounts, the Black Fountain Stereo Delay SL secures a permanent spot on users' pedalboards, an endorsement of both utility and sound quality.

MIDI and Preset Integration

Expression and MIDI unlock advanced workflows: every knob and parameter responds to both external expression pedals and MIDI control. This is especially relevant for users bringing the delay into complex digital rigs where automation and recall are essential. Preset selection via MIDI extends the pedal's performance capabilities, allowing musicians to flip between radically different delay setups on the fly.

Analog Dry Path and Switching

Despite being fully digital in processing, the Black Fountain Stereo Delay SL maintains an analog direct signal path. This ensures uncolored dry tone, a crucial demand for purists who want to keep inherent instrument character. Trails mode preserves delay repeats after bypass for fluid transitions; true bypass, on the other hand, severs the signal for those who prefer absolute transparency.

Build and Aesthetics

The enclosure measures 108 x 126 x 69 mm and weighs 454 grams. The slate finish lends a muted yet distinctive presence, while all components are assembled by hand in the USA. Build quality feels sturdy, jacks, footswitches, and pots all operate with precision, suitable for repeated stage or studio use.

Power and Practical Notes

The 9V DC supply requirement at 350 mA rules out battery operation, and since no adapter is included, users will need to ensure an adequate pedalboard power source. The current draw is reflective of its digital processing horsepower and MIDI functions. Those considering integration into larger pedalboards should note this power requirement as well as the slightly higher profile of rear plug connections due to enclosure shape.

Conclusion: A Creative Delay Engine for Forward-Thinking Musicians

Old Blood Noise Endeavors delivers a delay pedal at the crossroads of hands-on versatility and modern rig needs. With full stereo routing, MIDI, expression control, and analog dry-through, the Black Fountain Stereo Delay SL is engineered for players seeking more than standard digital delay. While cable orientation on the back panel may require planning, users consistently praise its inspiring sound and operational depth. For guitarists and electronic musicians alike, this pedal stands out as a robust and expressive tool ready for experimental and practical use cases.
