5 pedals on Tonebox

drolo is a small Belgian effects pedal builder founded by David Rolo. It is known for experimental designs that sit outside the usual overdrive-and-delay categories: the Stamme[n], a multi-function glitch and looping pedal, and the Molecular Disruptor, a DSP based multi-effect, are its best-known products. The pedals are built in Belgium123.

The range

The Stamme[n] and what it does

The Stamme[n] is the pedal drolo is most associated with. The maker describes it as having evolved over the years into "a micro looper / time stretcher / glitch delay / tape machine / infinite sustainer / reverb"4. It is not a single traditional effect: it captures short fragments of audio and manipulates them, which places it closer to experimental looping and delay territory than a conventional pedal of either type.

The pedal originated from an initial idea of Kent Sommer, who built under the name UglyCasanova and now trades as digitalflorafx4.

One detail players should know about its operation: in the SW swell mode, the output of the effect remains connected even when the pedal is bypassed, so that the audio can fade out appropriately4.

The pedal range

drolo's catalog covers several experimental formats. Most of the range is listed as sold out on the maker's own site as of October 2026, which is typical of a small hand-built operation546.

A few notes on individual pedals:

  • Strands can be used like a delay pedal, loop short audio bits, and create evolving rhythmic or melodic patterns3.
  • Kiwami is a filter pedal with what the maker calls "a couple of fun things going on"10.
  • Stretch Weaver was conceived with the musicians Scott Amendola and Nels Cline in mind, and its name is an homage to their duo project Stretch Woven9.
  • Giant Hogweed carries a Level control that adjusts the overall volume of the pedal12.

The Molecular Disruptor and its modules

The Molecular Disruptor is a DSP based multi-effect pedal2, placing it in the same digital territory as makers like Strymon, whose pedals also use DSP. It is currently listed as sold out6.

drolo also offers the Molecular Module, an expansion for the Disruptor. A compatibility note matters here: the modules are only available for Molecular Disruptor pedals with version 3.3 or newer, and the version is printed on the circuit board inside the pedal13.

If you own a Molecular Disruptor, check the version printed on the circuit board inside the pedal before seeking a Molecular Module. Modules only fit version 3.3 or newer13.

Where drolo fits

drolo is a Belgian builder in the experimental corner of the boutique pedal world. Its pedals are made in Belgium123, and its designs lean toward glitch, looping, time stretching and filtering rather than the overdrive, distortion and fuzz pedals that dominate the boutique market. For a player interested in that territory, the Stamme[n] and Strands are the entry points; for a multi-effect in pedal form, the Molecular Disruptor is the maker's DSP offering.
