All right, as promised... I've tested out the newest Electro-Harmonix chorus pedals! They came into my local shop a few days ago, so I went in this evening and gave them both a try. I came home with one - I'll get into that in a sec. So... first up is the Nano Clone. It's a tiny little pedal, with just one knob. The chorus depth is preset, and Based on comparing it to the Clone Theory and playing back my old Small Clone demo clips, it sounds like the Nano Clone is using a depth preset similar to the depth switch when pushed UP on the Small Clone. So basically, it's lush, organic, and as wonderful as the original Small Clone. Here's the drawbacks I noticed: - No depth switch means no "subtle" chorus - but we don't need subtle chorus anyway - It's a bit "hissy." At first, I thought it was just the pickups on the Fender MIM Jazz I was using to test the pedal, but in addition to the jazz coil noise, it has its own hiss. So, overall... it really is essentially a small version of the original, minus the option of mild chorus. Now, the Stereo Clone Theory. I took this one home for lots of reasons. The Clone Theory has three knobs - Mode, Depth, and Rate. Depth and Rate are self-explanatory if you've worked with chorus before. Now, the Mode knob is special. The pic above isn't very clear, but if you look at the three options on the Mode knob, the last two are a light blue text, the same as the Depth knob text. Everything else is standard white text. The manual explains why: The first chorus mode (CHR 1) is a preset-depth chorus, about the same as the Nano Clone. The Depth knob doesn't work in this mode. Adjust the Rate knob to taste, and it's good to go. The second chorus mode (CHR 2) allows you to adjust the depth to your liking, and allows you to do everything from subtle chorus to over-the-top (more so than the Small Clone, to my ears). The third mode is Vibrato. In this mode, the dry signal that normally gets mixed with the wet signal (for the chorus effect) is not present, so you just get that warbly, slightly "detuned" effect that vibrato is famous for, without the underlying dry signal. Adjust depth and rate to taste, and you're set. I haven't found much use for this mode yet, but I like it regardless, and may find an application for it soon. It seems like it could be really useful for me at low-rate settings. In all modes, there's hardly any hiss; it sounds "cleaner" than the Nano Clone did. When I brought the Clone Theory home, I plugged it in to my GK 2001RB, and the "hiss" noise was minimal. This leads me to believe that either the amp at the shop, or that Jazz bass, may have made that Nano Clone sound hissier than usual. Well, that, and they're analog pedals - bound to have a little noise one way or another. However, in terms of features, hiss, and style, the Clone Theory wins on all counts. This was everything I'd hoped it to be. In regards to the stereo function, I don't have a way of trying it out. I read the manual, and it says the stereo output is 180 degrees out of phase with the main output, to allow for a "panning" chorus effect of sorts between two amps. Sounds great, but without a second amp, I won't know how great it might be. Nevertheless, I doubt it'd be bad. My board is complete once again! Final Verdict: I approve of Cloning P.S. I'll try to post some demo clips of the Clone Theory when I find time. For now... if you're a Small Clone fan, consider this as a replacement if you want more control and flexibility on the chorus extremes, as well as a nifty vibrato option, a convenient preset chorus option, and the ability to go stereo! If you want to save cash and don't need any extra gizmos and knobs on your pedal, the Nano Clone would work fine, I'd imagine, but I'd be sure to test it out with your rig to make sure the hiss isn't an issue.
