Envelope controlled filter is an effect type that ventures beyond the mainstream yet is equally at home in a wide range of genres and equally effective on guitar, bass, keys, horns and more. Electro-Harmonix is a pioneer in this effect category and has been making envelope controlled filter pedals since the 1970s! The Nano Q-Tron springboards off that deep heritage.

Here’s how it works: The Nano Q-Tron responds to the user’s playing style and dynamics. The volume of the input signal it receives (also called the envelope) controls the cutoff or center frequency of a swept filter. This allows the Nano Q-Tron to create tone-altering effects ranging from subtle to dynamic, auto-wah to ultra-funky. It’s all about how you play and it’s super interactive.

The EHX Signal Pad is a passive attenuator that allows you to instantly switch to a different preset volume. It’s like your guitar’s volume knob, with a fully-passive and color-free circuit. Leave your amp’s volume set high for overdrive, and use the Signal Pad to lower your level for a clean sound — then switch it off to kick in your amp’s natural overdrive. You can also experiment with the Signal Pad anywhere in your effects chain — you’ll bring out new tonal combinations from your favorite old pedals.

Turn any single channel amp into a two channel setup
Switch from lead to rhythm on the fly
Use in front or after any effects to change the tone of that effect
True bypass
9V battery included

Signal Pad

Die Pitch Fork von Electro Harmonix in unserem aktuellen bonedo-Test beweist einmal mehr, dass auch Pitch-Shifter Effektpedale inzwischen für jedes Budget erschwinglich sind. Dieser Effekt, der in den Achtzigern in einigen berühmten Gitarrenaufnahmen auftauchte, war damals für uns “normale” Musiker kaum erschwinglich. Aber diese Zeiten haben sich glücklicherweise geändert. Pitch-Effekte sind inzwischen im Effektangebot vieler Hersteller zu recht günstigen Kursen zu finden.

The EHX Pitch Fork transposes an instrument’s pitch over a +/- three octave range and features three modes which allow the pitch to be transposed up, down or both, simultaneously. The pitch shift amount can be set to a fixed interval or continuously varied by an expression pedal or control voltage.
