and it's (drum roll)............................................................................. DLS Ultra Chorus II Here's a list of the chorus pedals I've tried over the past couple of years Ibanez original CS-9 Maxon CS-9 Pro Fulltone Choralflange Arion SCHZ EH Small Clone EH Clone Theory Boss CE-1 Boss CE-2 MIJ Boss BF-2 (chorus setting) MXR Stereo Chorus BBE Mind Bender Line 6 MM4 Eventide ModFactor The only good ones I haven't owned are the Retro Sonic, Red Witch and Analogman. The Retro is ostensibly the same as the CE-1, and the Analogman is supposed to be based on a Small Clone. This thing has everything that's good about all the best choruses wrapped up in one package. Here's my personal list of elements that make a great chorus. the DLS has got them all. wide range of textures, from subtle to intense good speed and depth range, for simulating rotating speakers adjustable delay time independent control over two discreet sets of rate and depth controls control over input AND output levels true bypass stereo in and out solidly built in USA preserves the original tone--no drastic bass cut, mid boost, or high frequency "sheen" LED's pulse in time with the effect rate sounds 'organic', meaning neither digitally sterile, nor analog metalic sounds equally good with clean and overdriven tones user friendly--easy to get the tones you want Bottom line, from the first note I knew this was the one, and further tweaking confirmed my initial impression. This is simply an exceptionally good chorus pedal.
