Dedalo FX Tremolo TRS-5

The Dedalo FX Tremolo TRS-5 is an analog tremolo pedal from the Argentine maker Dedalo FX. It shapes a guitar's volume in repeating cycles, and its maker describes its range as running "from the classic 'vibrato' of old, to modern rhythmic patterns and Fade/Kill effects"¹. In other words, one pedal covers the slow, even swell players associate with vintage tremolo, plus tempo-based patterns and a fade-to-silence effect.

How it works

The TRS-5's audio path is analog, built around what Dedalo calls a FET/LDR circuit. That pairs a field-effect transistor with a light-dependent resistor, an optical approach RockBoard's PedalPedia says "provides the most organic oscillation"¹. A micro-control section, which Dedalo brands μ-control technology, drives that analog path and makes the pedal's modes possible¹.

What it does

The pedal's modes cover three broad territories:

Classic vibrato-style tremolo: the traditional even rise and fall in volume
Modern rhythmic patterns: shaped, tempo-based modulation rather than a simple wave
Fade/Kill effects: swells and cuts that take the signal to silence¹

For a player, that means the TRS-5 can sit on a board as a conventional tremolo or be pushed into choppier, pattern-based territory without changing pedals. It belongs to the same family of effects as vibrato pedals, though tremolo works on volume rather than pitch¹.

Power

The TRS-5 runs on a 9V DC center-negative supply and draws 40mA¹. That is a standard pedalboard supply requirement, though it is above what some low-draw daisy-chain setups comfortably spare, so it is worth accounting for on a crowded board.

Dedalo publishes an English manual for the TRS-5 on its own site, which covers the pedal's controls in detail¹.

Questions

Is the Dedalo FX Tremolo TRS-5 analog or digital?

The TRS-5 is an analog pedal. Its audio path uses a FET/LDR circuit, the same optical approach found in classic tremolo designs, while a micro-control section handles the mode selection and timing. Dedalo describes the FET/LDR circuit as providing organic oscillation, and the pedal runs on a standard 9V DC center-negative supply at 40mA.

What can the TRS-5 tremolo do beyond a basic tremolo?

Alongside the classic vibrato-style tremolo of older designs, the TRS-5 offers modern rhythmic patterns and Fade/Kill effects. That makes it usable as a straightforward amplitude wobble, as a tempo-based rhythmic chopper, or as a momentary kill switch effect, all from one pedal.
