A beautiful sounding demo of the Merlo Harmonic Tremolo, with hypnotic guitar loops and excellent recording quality that make this perfect for headphone listening.

Ponderer Sounds applies their creative and unconventional approach to the Spira.

Merlo offers a sine wave tremolo shape just like other harmonic tremolos, and also provides an infinite variety of other shapes, thanks to frequency modulation (FM).

How Merlo allows control of harmonic tremolo crossover, filter shapes, and more. Journey far beyond the Brownface.

We’re excited to announce an updated look for Spira and Merlo.

We’re excited to share Joe Gore’s review of Spira for Premier Guitar, and honored to receive their Premier Gear Award!

Aaron Cloutier is back with a new track featuring Spira. On this track, Aaron delivers a spacious dark ambient feel, leaving lots of room for the Spira to do its work.

We invited musician/writer/producer Aaron Cloutier (and creative force behind Davola) to try out Spira with a few different fuzz pedals, and he came up with some awesomely heavy riffs on this dual guitar track.

We’re excited to announce that the Spira filter modulation pedal is now $249.
