The Supro 1313 Delay is an analog delay pedal from Supro, built around a pair of MN3005 bucket brigade (BBD) chips, the same kind of chip that gave vintage analog delays their character. Its circuitry comes from Howard Davis, the designer of the Deluxe Memory Man, which gives the pedal a direct line to one of the most respected analog echo designs1. It sits in the wider family of delay pedals alongside Supro's own Supro Delay and Supro Delay Hi-Fi Analog Echo.
Controls and how they work
The pedal carries the controls players expect from an analog delay, plus an expression input that extends what each one can do1.
| Control | What it does |
|---|---|
| Delay Time | Sets the delay time, up to a maximum of 600ms1 |
| Repeats (feedback) | Sets the number of repeats, and can be pushed into self-oscillation1 |
| Volume | Sets the output level1 |
| Expression input | Can be assigned to take on the individual functions of the three other knobs1 |
The 600ms maximum is worth noting for players comparing it against vintage units: MusicRadar's reviewer points out it runs longer than many of them1.
Self-oscillation under foot control
Feedback runaway is a signature trick of BBD delays, and the 1313 handles it in a way that can be played rather than just switched on1.
"The old staple of turning up the feedback to the point of self-oscillation now has the possibility of being conjured up"
The pedal lets you push the feedback into self-oscillation and then pull it back while playing, using foot control1. Combined with the assignable expression input, that makes the pedal's wilder side something you can ride in real time instead of setting by hand.
What reviewers said
MusicRadar's review, by Trevor Curwen, frames the 1313 as a way to get classic bucket brigade analog sound in modern pedal form, with the connection to the Deluxe Memory Man era as part of the appeal1.
"its tonal variations and expression options make this a smart way to put that sound on your 'board."
The reviewer's overall verdict credits the tonal variations and expression options with adding versatility to what is, at its core, a pure analog BBD delay1.

Questions
Is the Supro 1313 a true analog delay?
Yes. MusicRadar's reviewer Trevor Curwen describes it as a way to put pure analog BBD sound on a pedalboard, with the analog signal path built around a pair of MN3005 bucket brigade chips. There is no digital conversion in the delay path, which is what separates it from digital or analog-modeling delays.
Who designed the Supro 1313 Analog Delay?
The circuitry was designed by Howard Davis, who MusicRadar identifies as the designer of the Electro-Harmonix Deluxe Memory Man. That gives the 1313 a direct connection to one of the best-known analog delay designs, and the pedal's sound is described as being based on that era of bucket brigade circuitry.
What is the maximum delay time on the Supro 1313?
The maximum delay time is 600ms, which MusicRadar notes is longer than many vintage units. Delay time is set with a dedicated Delay Time knob alongside controls for repeats and volume.
Can you use an expression pedal with the Supro 1313?
Yes. An expression pedal can be assigned to take on the individual functions of the three other knobs, so you can sweep delay time, repeats or volume by foot while playing. MusicRadar's reviewer counted the expression options among the features that add versatility to the pedal.
Can the Supro 1313 self-oscillate?
Yes. Turning up the feedback to the point of self-oscillation is possible, and the oscillation can be pulled back while playing via foot control. MusicRadar describes this as an old staple of analog delay playing that the 1313 handles in a playable way.
