Q-Balls, that is… Introducing the new RIDDLE: Q-Balls from Electro-Harmonix, an envelope filter for guitar. The RIDDLE also has a brother for bass called the ENIGMA: Q-Balls.
So what exactly is the RIDDLE? As EHX put it, the RIDDLE is an “envelope controlled filter for guitar.” Synthesizer players have long known the beauty of adjusting a signal’s envelope or volume profile by emphasizing or limiting certain frequencies to create wholly unique sounds. Now, apparently, that is available for guitar with the RIDDLE. Check out this very cool demo video:
Damn! He did all that with an acoustic guitar!
I’ve grown to appreciate EHX over the last couple of years as they’ve come up with some really cool, thinking out-of-the-box pedals, like the Q-Tron, and of course, the POG. Yeah, they have your basic overdrive, distortion, delays, reverbs, etc., but stuff like the RIDDLE that open up the tonal possibilities of your guitar are quite commendable.
I’m not sure if the RIDDLE is something I’d use, but I’m writing about it here just because of its cool factor. Maybe I’ll take some time this weekend to see if I can’t check it out at a store.
For more information on the RIDDLE, go to the EXH web site.
