Electro Harmonix Q-Tron Plus
The Electro Harmonix Q Tron Plus is the newest addition to EH's sweet and sick envelope filter, the Q Tron. The Q Tron Plus offers all of the funky and phat sounds of the the original Q Tron envelope filter. Responsive to your picking attack and completely organic in tone, the Q Tron Plus is the classic envelope filter plus a couple of new features that make it a must-have for envelope filter junkies. First, the Q Tron Plus has an effects loop. What this does is runs your effects in series with the Q Tron, so the original dynamic of the Q Tron remains untouched by the pedals you place in the loop. So add a distortion and hear the original dynamics of your envelope filter, but with the distortion tone added to filter of the Q Tron. Very cool. Or add a delay in the effects loop, so you will hear the filter opening and closing on the delay signal, rather the delay affecting the dynamics. This really opens up the sonic possibilities of the Q Tron. Also on board with the Electro Harmonix Q Tron Plus is the addition of a attack response switch, which selects either a slow, smooth, vowel-like attack or the fast, snappy response of the original Q-Tron.
Electro Harmonix Q Tron Plus
With an added effects loop and attack response switch, this is the Q Tron you've been waiting for. With the ability to run delays and overdrives in the effects loop, now your picking dynamics will not be overpowered by your other stompboxes - instead, you will hear the effect on the effect filter rather than on your original signal dynamic.
