The TWA Fly Boys FB-03 Echo is a delay pedal from TWA. It offers 600 milliseconds of what the maker calls "gorgeous, transparent delay time," aimed at slapback echo and rhythmic doubling1. Pedal of the Day reviewed it in 2015 and described it as having "a bright and shiny echo sound"2.
What sets it apart from a plain digital delay is the character of the repeats. TWA says the repeats carry "a slight hint of tape-like wobble, adding an authentic analog realism to each repeat"31. The pedal can also be pushed into self-oscillation, which the maker describes as creating "pulsing soundscapes and UFO-landing modulation effects"1.
What it does to your sound
The FB-03 Echo is a digital delay, but it is voiced to avoid the sterile character some players associate with digital repeats. Pedal of the Day's reviewer, Mike B, wrote2:
"This little digital delay produces a bright and shiny echo sound"
Mike B, Pedal of the Day2
That brightness is the pedal's defining trait. TWA describes a crisp delay tone that can brighten a dark rig or room, and the tape-like wobble on the repeats keeps them from sounding purely clinical1. For players whose setup leans dark, that makes it a useful contrast piece. Pedal of the Day found exactly that use for it:
"which works as a perfect companion to a darker analog delay in your chain"2
Mike B, Pedal of the Day2
In other words, the FB-03 can sit alongside a darker analog delay rather than replacing one, with each covering a different end of the delay spectrum.
Controls
The FB-03 Echo keeps its control set minimal, with three knobs:
| Control | What it does |
|---|---|
| Rate | Sets the delay time, maxing out at 600ms; a large knob for on-the-fly adjustments2 |
| Echo | Controls the number of repeats the delayed signal has2 |
| Intense | Adjusts the overall delayed sound mixed with your guitar's original dry signal2 |
The large Rate knob is worth noting for live use: Pedal of the Day highlighted it as being sized for on-the-fly adjustments, so you can dial in a new delay time mid-song without hunting for a small knob2.
Self-oscillation and ambient effects
Beyond conventional echo, the FB-03 can be manipulated into self-oscillation, where the repeats build on themselves into runaway feedback. TWA frames this as a feature for experimental players, describing "pulsing soundscapes and UFO-landing modulation effects"1. This is the kind of behavior players associate with vintage tape and analog delays, and it is unusual to find on a small digital pedal at this price point.
Where it came from
Guitar World reported on the TWA Fly Boys mini effect pedals in November 2013, listing the FB-03 Echo with "600 milliseconds of gorgeous, transparent delay time"7. That places the pedal's introduction in the Fly Boys mini-pedal line in 2013, with the Pedal of the Day review following in August 201527.

Questions
Is the TWA Fly Boys FB-03 Echo analog or digital?
It is a digital delay. Pedal of the Day described it as a little digital delay that produces a bright and shiny echo sound, though the repeats carry a slight tape-like wobble that adds analog realism to each repeat.
What is the maximum delay time on the FB-03 Echo?
The maximum delay time is 600 milliseconds. TWA positions that range as well suited to slapback echo and rhythmic doubling rather than long ambient delays.
Can the FB-03 Echo self-oscillate?
Yes. TWA says the FB-03 can be manipulated into self-oscillation, creating pulsing soundscapes and what the maker calls UFO-landing modulation effects.
What does the Intense knob do on the FB-03 Echo?
Intense adjusts the overall delayed sound mixed with your guitar's original dry signal, in effect setting the balance between the effect and your clean tone.
Does the FB-03 Echo work well with a darker analog delay?
Yes, according to Pedal of the Day. The reviewer found its bright, crisp repeats work as a perfect companion to a darker analog delay in your chain.
Does the FB-03 Echo come with a cable?
Yes. Godlyke includes a free C-BAT/R cable with every Fly Boys purchase, so the FB-03 Echo ships with one.
