Beetronics Bee Bee Dee

The Beetronics Bee Bee Dee is an analog delay pedal built around two bucket-brigade (BBD) chips, the classic circuit type behind the warm, darkening echoes of vintage delay boxes. What sets it apart is a digital control engine wrapped around that analog path, which lets it do things a conventional BBD delay cannot: tap tempo with subdivisions, a performance footswitch with three assignable functions, and a Pitch mode that shifts the repeats in pitch¹².

What it does: BBD delay with modulation and pitch

The Bee Bee Dee's signal path is analog: two bucket brigade chips pass your signal along in discrete steps, which is what gives BBD delays their characteristic warm repeats that lose a little brightness each time around¹. Guitar World's reviewer found the basic voice, with the Tone knob at its neutral 12 o'clock position, "typically analogue, giving a clean initial repeat that mirrors your dry sound, with subsequent repeats exhibiting subtle tonality changes that let them blend smoothly into your sound"¹.

On top of that analog core sits the digital control layer. Delicious Audio describes the pedal as "a creative instrument built around a true bucket-brigade (BBD) analog signal path but enhanced with intelligent digital control"³. That control layer is what makes the tap tempo, the tempo-synced pitch modulation and the assignable footswitch possible.

Classic, Lo-Fi and Pitch modes

A three-way toggle selects the mode, and each one changes what the Depth and Activity knobs do¹.

In Pitch mode, the Depth knob selects the pitch interval, and Guitar World notes that the noon position gives an octave pitch change that stays automatically in tune¹. The Tone control is unusual for a BBD delay: it is a three-position-style sweep with low-pass to the left, neutral in the middle and high-pass to the right, and Beetronics calls it the only BBD delay that goes both ways⁸⁹. Turning it right thins the body of the repeats for something brighter, sharper and grittier; turning it left rolls off the top end for warmer, darker repeats¹.

Guitar.com's Richard Purvis summed up the Lo-Fi mode's character:

The two footswitches

The right-hand footswitch is the bypass switch, with extra tricks. Besides standard latching bypass it has a momentary action for quick bursts of effect, and press-and-hold while engaged ramps the feedback up into oscillation¹.

The left-hand Performance footswitch is assignable by the toggle switch above it, with three functions¹²:

• Tap Tempo: tap to set the delay time; hold and turn the Activity knob to select the tap division⁶¹
• 2X: doubles the delay speed and shifts the feedback by an octave¹
• Mod: toggles the modulation on and off, momentary or latched¹¹

The face of the pedal carries six knobs, the two footswitches and two three-way toggles¹⁰. Alongside Time, Tone, Depth, Activity and Mix (dry/wet), there is the usual feedback control for the number of repeats¹.

Where it came from

What reviewers said

Guitar World's Trevor Curwen found the pedal strong for conventional delay work, writing that "For straight delay tasks, the Bee Bee Dee is excellent, combining classic analogue sound, a practical range of delay times and nicely applied modulation with practical elements not normally found in a conventional analogue delay"¹. He noted that the Time knob's clean range runs to 600ms at about its one o'clock position, with times increasing but clarity decreasing beyond that¹.
