Yep, the MXR Carbon Copy Analog Delay is a true bypass pedal. This means that when you switch it off, it won't mess with your guitar signal—your tone stays just as it is. That's straight from the manufacturer's product description.

Now, about the mono output: the Carbon Copy is set up for mono, not stereo. It’s got a single 1/4-inch input and output, focusing on a mono signal to give you those classic, rich delay tones.

But what it lacks in stereo, it makes up for with its warm, lush delays. You get up to 600 milliseconds of delay time, thanks to the bucket brigade circuitry. It's easy to use with three knobs for delay time, mix, and regeneration, plus a modulation button for a bit of a chorus vibe. Our research shows it's super popular with musicians who need a solid mono delay.

If stereo is a must for you, you might have to get creative. Some folks use additional gear like stereo splitting boxes or even two of these pedals to get a stereo effect. So, it's possible if you're willing to experiment a bit.

For those who can't do without stereo, you might want to check out alternatives like the Eventide TimeFactor, which comes with stereo built-in.

But remember, our research highlights that the Carbon Copy is loved for its warm sound and reliable build. It's a mainstay for a lot of players who want good-quality analog delay without any tone loss.

So, if keeping your signal pure is what you're after, the Carbon Copy’s true bypass should do the trick, all while delivering those warm, charming analog delays.

The MXR Carbon Copy Analog Delay pedal is pretty famous for its warm and rich analog delay sounds. It works with bucket-brigade technology, giving you delay times up to 600ms. This means you can create anything from quick, punchy 'slapback' echoes to larger, more atmospheric delays.

From what we've found, people really love the nostalgic and lush tones the Carbon Copy offers. It's also got a solid build. There are just three knobs to mess with: delay time, mix, and regeneration, which makes it simple and appealing for those who want that classic analog vibe without the complexity.

Now, about that modulation feature—it's a neat addition that adds a tape-like warble to your echoes, kind of like old-school tape delays. You can adjust this modulation effect with some internal trim pots. However, keep in mind that you'll have to open up the pedal to do this, which isn't as convenient as just turning a knob on the outside.

While many folks rave about the pedal, there are a few things to keep in mind. According to our research, some people aren't thrilled with the modulation's accessibility and mention that the delay repeats can sound a bit dark. This might be a downside for you if you're after something brighter or if you want features like tap tempo, which isn't included here.

All in all, even with a few critiques, the MXR Carbon Copy is still a favorite for producing classic analog delay sounds. It's loved for its tone, straightforward operation, and sturdy design, so if you're after authentic analog echo effects, it's a great option to consider.

The MXR Carbon Copy Analog Delay pedal has a pretty decent delay time range. According to the manufacturer's description, you can set it anywhere from 20 to 600 milliseconds. So, whether you need a quick slap-back delay or a longer, atmospheric echo, this pedal has got you covered.

The pedal also includes a cool modulation feature. It's supposed to give your sound a bit of that old-school tape echo vibe by adding a subtle pitch shift. You can turn this on with the 'MOD' switch, and if you're into tinkering, there are internal trim pots to tweak the width and speed of the modulation.

Just a heads up though—you'll need to remove the base plate to get to them.

From what we've gathered, people really like the warm and rich tones that this modulation brings to the delay. It seems to work well for everything from classic rock and blues to more experimental music.

So, if you're looking for a pedal that offers a wide range of delay options and some vintage-inspired modulation, the Carbon Copy is worth checking out.
