The Retro-Sonic 800ms Analog Delay is an analog delay pedal from Retro-Sonic, a compact unit with four knobs covering delay time, repeats, level and tone, plus a Long/Short switch that selects between two delay ranges. It runs on a 9VDC negative center adapter and draws 25 mA1.
Controls and switches
The pedal carries four controls and two switches on its top panel1:
| Control | What it does |
|---|---|
| Repeat Rate | Sets the delay time |
| Intensity | Sets the amount of repeats |
| Echo | Sets the level of the delayed signal |
| Tone | Shapes the tone of the repeats |
Alongside the knobs there are two switches: a Normal/Effect switch and a Long/Short switch1. The Long/Short switch is what gives the pedal its name, selecting between the two delay ranges, with 800 ms describing the pedal's longer reach. The Normal/Effect switch handles the effect in and out functions.
Power and connections
The 800ms Analog Delay takes a 9VDC negative center adapter and draws 25 mA1. Both the input and output are ¼-inch standard phone jacks1.
The pedal runs on a 9VDC neg center adapter power supply, with a ¼-inch standard phone jack input jack and a ¼-inch standard phone jack output jack, and measures 4.7 x 3.7 x 1.18 inches1.
Questions
What polarity does the Retro-Sonic analog delay need?
Retro-Sonic specifies a 9VDC negative center adapter as the power supply for the 800ms Analog Delay. As with most negative center pedals, use a supply that matches that polarity and do not assume a positive center adapter will work. The pedal takes its power from a standard adapter rather than any other arrangement, so a matching 9VDC negative center supply is what to run it from.
How much current does the Retro-Sonic 800ms Analog Delay draw?
The Retro-Sonic 800ms Analog Delay draws 25 mA, according to the maker's product page. That figure matters when planning a pedalboard power supply: add the pedal's 25 mA to the draw of everything else sharing a supply output or daisy chain and make sure the supply can cover the total.
What does the Long/Short switch do?
The 800ms Analog Delay has two switches: a Normal/Effect switch and a Long/Short switch. The Long/Short switch selects between two delay ranges, with the pedal's 800 ms figure describing its longer setting. The Normal/Effect switch handles the bypass and effect functions of the pedal.
Is the Retro-Sonic 800ms Analog Delay still available?
That is the maker's own listing, so it is the current status of the pedal from the company that builds it.
How much did the Retro-Sonic Analog Delay cost?
Retro-Sonic listed the 800ms Analog Delay at US$249.00 on its product page. That is the maker's own price in US dollars as shown on the page.
