Aha.... Perky... I never realised you were a TGPr... I like your videos!!! As you can see above.I've got one - it's amazing, in that it's a hugely inspiring and unique sound that's so timeless. Personally, I absolutely love it. Plus, it's stereo (well...seperates the Wet & Dry onto separate channels, so...kinda stereo) and has the vibrato mode.
But - the preamp is always active, so colours your overall sound even when the chorus is off. It's mains powered. It's noisy. It's not true bypass. It's f'ing enormous! And, nowadays, crazy money. There's a few pedal folks (Analog Mike, etc) who do mods to sort the True Bypass; and I've even seen some converted to accept a Boss-style power input. But also...they're old, they're prone to breaking down, etc. And if something inside it breaks, the resale value goes through the floor. Plus, you need to either modify it and replace the preamp pot or always give it a buffered signal to stop it shelving off all your high end.
A few people make amazing clones of it - Retro Sonic being one - with the 'issues' fixed. So...it entirely depends if you want 'THE' unit, or just the sound. If you're a collector/vintage purist then yeah...track down an original. But if you're just after "an analog chorus" there's hundreds of more practical, cheaper & more versatile options out there. The Analogman Mini Chorus is the one I use on my board & the JAM Waterfall is also amazing, to name but two high-end boutique choruses.
But yeah...the CE-1 is epic! ;-)
Maybe a more intricate look at the CE1 in chorus mode might be in order...
