oh wow

I didn't know I still had one of these... its a 90s version. It sounds good and has lots of useful features versus like a small clone or CE2 but its therefore harder to dial in because there are lots of bad settings. he stereo is VERY stereo sounding when you make use of it. Great for synthesizers and worth a shot when you're mixing a record and want to add some swirl to your echo sends. Sold, since having the TC reissue analog chorus/flange I never touched this even for true stereo duty. The tone controls for the wet signal are cool, but its inferior to the TC unit in every other way right down to the TC having true stereo input and the ability to change the input gain for synths and mixing...

miguel_angelo

A modern classic... Awesome

It's awesome. Period. Since i got it that it is always on, slow and wide. You can really shape and fine tune your chorus for multiple combinations, and guess what, they all sound killer. (have you hear it through a synthesizer or bass? the stereo just slays.....)

Since i play an 8 string the bass cut feature is an exceptional tool to keep my low end tight and retaining that choirish vibe on the medium and top end.

Super versatile, awesome sound, superb 100% analog construction. No true bypass, but honestly i can't tell the difference in the sound.

I also love the blinking led. It blinks in time with the rate of the chorus, it's just cool to have it there and visualize what your doing to your sound.

stefanobras

Got it for the aesthetics, kept it for the joy.

If you play indie music or a more slow-oriented kind of guitar sound, this shit is the bomb. Got it because Matthew Healy had one and the pedal itself is just so damn beautiful, but it quickly became an essential part of my pedalboard and it added a lot of personality to my sound

cwirus88

Can't go wrong with it

100% analog circuit, lush and warm tone, huge headroom (runs on 18v) and very tweakable. Probably the best chorus ever which allows user to dial into wide range of sounds - from classic cheesy 80s leads to leslie-a-like and everything in between. It is worth to experiment with its placement. Also you can use as a kind of post-gain EQ. I dig the blinking led light, it allows you to see how fast is the modulation.

edoardo_del_principe

The pros win over the cons

Pros: Highly responsive EQ| dynamic use of the oscillation to calibrate the pedal between a rotary and a flangy chorus| Warm analog sound. Cons: Need 18v| Lack of Dry/Wet knob| Maybe too big for some pedalboards For me it's between to category of chorus 1) the little packege user friendly pedal 2) big, sofisticated and expensive pedal Can I get the same tone with the micro version? NOPE. Can I get the same tone with a Boss CE3? Yes Can I find something better for the price? Yes, but not analog
