Keeley Electronics Introduces the Neutrino Envelope Filter

The Neutrino is a compact circuit of an opto-coupler-based design.

Edmond, OK (April 29, 2014) -- Keeley Electronics today announced it is now shipping its Neutrino Envelope Filter effect pedal.

The 100% hand-built Neutrino is a modern compact circuit of an opto-coupler based design and was created for the most demanding filter effects lovers. The Neutrino envelope filter/auto-wah offers a wealth of studio-quality musical tones, from classic wah sounds to vocal and vowel sounds all based on pick dynamics or input level.

With controls for input GAIN, resonance PEAK, FILTER selector, tone RANGE, and DRIVE direction the Neutrino makes it easy for players to dial in all of the classic auto wah tones. A side mounted and recessed Drive switch and internal output Volume were designed to keep the look ergonomically clean. Players have the needed controls at their finger-tips and other controls easily available for crafting emotive and expressive sounds.

"Our design team focused on building a tunable dual opto-coupler design that could be aligned for unit-to-unit perfection. Opto-coupler based envelopescan be expensive, bulky, and can have variances in sound quality so our goal was clear: create a best-in-class product that combines compact versatility, repeatable musical tone, and low noise in a compact effect," said Robert Keeley, founder and chief engineer, Keeley Electronics. "To achieve this, we employed several technical innovations from their successful Seafoam Chorus design. The end result is the Neutrino Envelope Filter is a studio-quality effect we are extremely proud of and excited to offer to our customers."

Like all of Keeley Electronics' designs, the Neutrino Envelope Filter is hand-built in the USA using the finest components and construction techniques. It is housed in a beautifully powder-coated and rugged enclosure, includes true bypass switching, and features a 2-year limited lifetime warranty with world-class Keeley customer support.

The Keeley Electronics Neutrino Envelope Filter is now shipping to dealers worldwide at a street price of $229.

My years-long search for the “right” Bigsby-outfitted box finally paid off. Now how do I make this sumbitch work in my band?

Considering the amount of time I’ve spent (here and elsewhere) talking about and lusting after Gretsch hollowbody guitars, it’s taken me a remarkably long time to end up with a big Bigsby-outfitted box I truly love. High-end Gretsches are pricey enough that, for a long time, I just couldn’t swing it. Years ago I had an Electromatic for a while, and it looked and played lovely, but didn’t have the open, blooming acoustic resonance I hoped for. A while later, I reviewed the stellar Players Edition Broadkaster semi-hollow, and it was so great in so many ways that I set my sights on it, eventually got one, and adore it to this day. Yet the full-hollowbody lust remained.
