The Nady FL-10 is a flanger pedal that Nady describes as a classic-style design, offering "dynamic flanging and four controls for seemingly endless sonic variation"1. A flanger mixes a short, modulated delay with the dry signal to produce the sweeping, jet-like sound associated with the effect; the FL-10's delay time runs from 0.3ms to 14.5ms, with an LFO speed range of 100ms to 20s1.
Nady positions it as an updated take on the classic flanger, and describes the result as "the smooth, deep sound of a classic flanger pedal"1. It is a compact, battery-powered pedal in an all-metal casing, built around a sturdy on/off footswitch and a single LED indicator.
Nady lists this pedal in its Legacy category and shows it as out of stock on its product page1. It is not presented as a current production item, so finding one means the used market.
Controls and what they do
The FL-10 has four controls. Nady's product page explains three of them directly1:
| Control | What it does |
|---|---|
| MANUAL | Adjusts the center frequency to which the effect is applied |
| DEPTH | Adjusts the sweep range |
| RATE | Adjusts the speed of the flanging effect |
For a player, that is the classic flanger recipe: Rate sets how fast the sweep moves, Depth sets how far it travels, and Manual sets where the sweep is centered. Together with the delay time range of 0.3ms to 14.5ms, these cover everything from slow, deep sweeps to fast, shallow shimmer1.
The LED indicator lights when the effect is on, and also serves as a battery check1. The on/off footswitch is described by Nady as sturdy, in keeping with the all-metal casing the company says provides "years of roadworthy reliability"1.
Power and connections
The FL-10 runs on a 9V alkaline battery, with a nominal battery life of 10 hours, which Nady notes varies depending on conditions of use1. An AC adapter is optional: Nady specifies its PAD-1 adapter, a 9VDC unit, connected through a dedicated AC adapter jack alongside the instrument input and output1.
Because the adapter is optional rather than included, a used FL-10 may arrive with no power supply, and the battery route is the default. The LED's battery-check function is the practical way to monitor that 10-hour nominal life1.
Specifications
Nady publishes a full set of measurements for the FL-101:
| Specification | Value |
|---|---|
| Input impedance | 1MΩ |
| Output impedance | 1kΩ |
| Recommended load impedance | >10kΩ |
| Nominal input level | -20dBu |
| Nominal output level | -20dBu |
| Residual noise level (A-weighted) | -90dBu typical |
| Delay time | 0.3ms to 14.5ms |
| LFO speed | 100ms to 20s |
The 1MΩ input impedance is the standard value for a guitar pedal input, and the -90dBu typical residual noise figure is quiet for a battery-powered analog-style stompbox1.
A note on the name
The FL-10 name is not unique to Nady. Valeton also lists an FL-10 flanger pedal, a heavy duty metal design with its own on/off status LED and a Depth control for flanger depth2. The two are separate products from separate makers; this page covers the Nady pedal.
Players comparing classic-style flangers can also look at pages for the Ibanez FL9, the Maxon FL-9 Flanger, and the MXR Flanger, all of which take a similar four-knob approach to the effect.

Questions
How long does a battery last in the Nady FL-10?
Nady rates battery life at 10 hours nominal with a 9V alkaline battery, and notes that it varies depending on conditions of use. The LED indicator doubles as a battery check, so a dim or dark LED when the effect is on is the cue that the battery is running down.
Does the Nady FL-10 come with an AC adapter?
No. The FL-10 runs on a 9V alkaline battery, and the AC adapter is optional. Nady specifies its own PAD-1 adapter, a 9VDC unit, through a dedicated AC adapter jack on the pedal.
What does the LED on the Nady FL-10 do?
The LED indicator lights when the effect is on, and it also serves as a battery check. That means it does two jobs at once: showing bypass status and giving a visual warning as the 9V battery weakens.
What does the Manual knob do on the Nady FL-10?
The Manual knob adjusts the center frequency to which the flanging effect is applied. In practice it shifts where the sweep sits, working alongside Depth, which sets the sweep range, and Rate, which sets the speed of the flanging.
Is the Nady FL-10 still made?
Nady lists the FL-10 in its Legacy category and shows it as out of stock on its own product page. It is not shown as a current production item, so players looking for one are effectively looking at the used market.
