General

This Nano edition Electro Harmonix stompbox neatly packs up the sound of the legendary Q-Tron and stuffs it inside a tiny metal box. This is classic analogue envelope filtering effects courtesy of the masters, and it's not exclusive to guitarists and bassists either, since this pedal can bring the full funk or some more subtle auto-wah to the sound of adventurous keyboardists, brass musicians, and producers. This is one powerful filter wrapped up in a true-bypass circuit for clean and professional performance.

The Nano Q-Tron

First, select the frequency range that you want the Q-Tron Nano to weave its magic with: LP (Low-Pass), BP (Band-Pass), or HP (High-Pass), which has the effect of emphasising the low, mid, or high-range frequencies in response to your playing dynamics. The effect intensity is dialled back or pushed to the extreme via the infamous Q-pot, and the sensitivity is set using the Drive pot. Adjust the effect volume to the preferred level and enjoy the delicious, sonic flavourings of this vintage-style envelope filter.

The EHX Qtron is an absolute beast on Bass!! Does everything you want and more besides. The Drive and Mode controls are fantastic, allowing for classic envelope filtering or some gnarly effects that sound incredible, especially with Fuzz!! Don't think about it, buy it!!!

Ik gebruik hem voor synths en brengt een leuke extra filter. Behoorlijk warm analoog. Maakt van piano zelfs funky. Net zoals alle AHX pedalen: prima kwaliteit en goed gebouwd. Gitaarpedalen sluit ik op synths telkens aan via een passieve reamp van Radial.
