The Morley MOD-DDB Deluxe Distortion is a vintage distortion pedal from the early 1980s, the product of a short-lived collaboration between Morley and Tel-Ray Electronics. It is a simple three-knob distortion built around a TL074 opamp, and it is rarely seen or discussed today.1
A short-lived Tel-Ray design
Pedal of the Day, reviewing the pedal in October 2024, opens with the history: "The MOD-DDB Deluxe Distortion was a short-lived collaboration between Morley and Tel-Ray Electronics in the early 1980's."1 That short run is the main reason the pedal is so little known. Morley is best remembered for its wah and switching pedals, and the company's distortion output of the period, such as the Morley MOD-D1B Distortion One and the Morley Just Distortion, sits in the same little-documented corner of its catalog. The MOD-DDB belongs to that family: a distortion pedal from a maker better known elsewhere.

Circuit and power
The pedal is built around a TL074 operational amplifier chip, and it runs on two 9 volt batteries or an optional AC adapter.1 The two-battery arrangement is worth noting for anyone planning a board: this is not a pedal that will share a standard single-9V daisy chain without an adapter, and players used to modern pedals should expect to source the right supply.
Controls
There are three controls, and Pedal of the Day found them quick to work with: "The simple Distortion, Tone and Output controls make it easy and quick to dial in a great distortion sound."1
| Control | What it does |
|---|---|
| Distortion | Sets the amount of distortion |
| Tone | Shapes the tone, with what the reviewer calls a huge sweep1 |
| Output | Sets the pedal's output level |
What reviewers said
The pedal's only recent published review, Pedal of the Day from 26 October 2024, is positive on both sound and looks. The reviewer describes it as a "vintage, classic distortion pedal" with "lots of saturation and bite without sacrificing any clarity or brilliance," and concludes that "both the sound it produces and the beat-up aesthetic make this one killer distortion pedal."1
On the tone controls, the same review notes that "the tone sweep is huge on this pedal which would lend itself to also being used as a bass distortion," making the MOD-DDB a candidate for players of bass as well as guitar.1

Questions
Who made the Morley MOD-DDB Deluxe Distortion?
The MOD-DDB Deluxe Distortion was a collaboration between Morley and Tel-Ray Electronics in the early 1980s. Pedal of the Day describes it as short-lived, and it remains a vintage pedal that is not widely discussed, which makes it an uncommon sight on boards and in listings today.
Does the Morley MOD-DDB take batteries or an AC adapter?
Both. According to Pedal of the Day, the pedal runs on two 9 volt batteries or an optional AC adapter. The two-battery arrangement is unusual among distortion pedals, so players used to a single 9V supply should plan around it.
Can the Morley MOD-DDB be used for bass?
Pedal of the Day suggests it can. The reviewer found the tone sweep is huge on this pedal, which would lend itself to also being used as a bass distortion, on top of its guitar duties.
What chip is inside the Morley MOD-DDB?
Pedal of the Day reports that the pedal uses a TL074 opamp based circuit. The TL074 is an operational amplifier chip, and the whole distortion circuit is built around it rather than around transistors or clipping diodes in the usual way.
How rare is the Morley MOD-DDB?
It is a short-lived, vintage pedal that is not widely discussed, in Pedal of the Day's words. The pedal dates from the early 1980s and was only made for a brief period, so examples do not come up often.
