Description
Low end doesn’t forgive sloppy repeats, and that’s exactly why the Mad Professor Deep Blue Delay earns a spot on a bass board. It runs a clean analog direct signal path alongside a digital delay engine tuned to feel like a vintage tape echo — same bandwidth, same organic decay, without extra noise reduction stripping the life out of your tail.
There’s no filtering coloring your dry signal, so your fundamental stays intact whether the DBD sits in front of your amp or inside an effects loop. The echo path itself has tuned filtering that lets you push delay time and repeats into extreme territory without the pedal falling apart on you — a real plus if you’re layering delay under a driven or fuzzed-out bass tone, which is usually where cheaper delays choke.
Controls are kept dead simple: Delay Time, Delay Level, and Repeat. It’s built as an ambience tool first, not a rhythmic delay box — the repeat formation is voiced so you don’t have to nail the beat precisely for it to sound right, even past 120ms.
- Delay time: approx. 25ms to 450ms
- Signal to noise ratio: 80dB
- Current draw: 25–32mA depending on setting
- Voltage range: 8V–15V (below 7.5V, delay signal mutes)
- Input impedance: 180K Ohms / Output drive: 10K Ohms
- 1/4″ Switchcraft in/out, true bypass with grounded input
- Compact footprint: 69mm x 111mm x 50mm
