The Supro Delay Hi-Fi Analog Echo is a compact delay pedal built entirely in the analog domain. Pedal of the Day describes it as "a small but powerful delay unit offering vintage echo sounds of the '60s and '70s," aimed at players after the character of old tape and analog echoes rather than pristine digital repeats1. It sits in the wider field of delay pedals as a dedicated analog echo design.
An all-analog echo built on two MN3005 chips
At the heart of the pedal are "a pair of high-voltage MN3005 IC chips capable of producing up to 600ms of delay time." The MN3005 is a bucket-brigade device, the kind of chip long associated with warm, darkening analog repeats. Supro's design runs these chips at high voltage, which the review credits with "dramatically increased headroom, dynamic range, and clarity"1.
Controls
The pedal keeps its front panel to four knobs, each with a single job:
| Control | What it does |
|---|---|
| Time | Controls the echo's length1 |
| Feedback | Sets the number of repeats in the delay line1 |
| Level | Sets your delay volume1 |
| Filter | Ranges from low-pass to band-pass functions, from dark, warm and murky tones to crisp and bright tape echoes1 |
The Filter knob is a newly designed feature on this pedal, and it is the control that shapes the color of the repeats: at one end of its travel the echoes sit dark and murky, at the other they take on the crisp, bright character of a tape echo1.
Expression pedal control
Beyond the knobs, the Supro Delay includes an assignable expression pedal input. Pedal of the Day explains that it "provides the player with the ability to switch between Repeats, Time and Level, while maintaining your custom knob settings"1. In practice that means one expression pedal can sweep delay time, repeat count or echo volume live, without losing the positions you have dialed in on the panel. If you are building a setup around this kind of control, see Expression Pedals.
What reviewers said
Pedal of the Day's verdict on the pedal was positive: "A great echo unit with some surprisingly excellent tones." The same review summed up its impression of the pedal's look and impact in a phrase: "this little red machine will transform your sound"1.

Questions
Is the Supro Delay fully analog?
Yes. Pedal of the Day describes the Supro Delay as an all-analog delay pedal, built around a pair of high-voltage MN3005 IC chips. The chips run at high voltage, which the review credits with dramatically increased headroom, dynamic range and clarity compared with lower-voltage designs.
How long is the maximum delay time on the Supro Delay?
The Supro Delay can produce up to 600ms of delay time, according to Pedal of the Day. The Time knob controls the echo's length, and the Feedback knob sets how many repeats sound before the echo dies away.
Who designed the Supro Delay?
According to Pedal of the Day, the Supro Delay was designed by Howard Davis.
Can you use an expression pedal with the Supro Delay?
Yes. The pedal has an assignable expression pedal control that lets you switch between controlling Repeats, Time and Level while keeping your custom knob settings, as described by Pedal of the Day.
What does the Filter knob do on the Supro Delay?
Pedal of the Day describes the Filter knob as ranging from low-pass to band-pass functions. It spans from dark, warm and murky tones to crisp and bright tape-echo-style sounds, shaping the tone of the repeats.
