    DAN AGOSTO: Hi. Welcome to Gearwire.Com. We’re taking a look at the MXR Micro Amp. It’s actually a booster pedal so really it doesn’t do much of anything except for give you clean volume. Let’s take a look inside of the box.

    All right. We got the Cry Baby catalog. This comes with every MXR pedal, just a bunch of wah wahs, and the MXR catalog, Phase 90s, choruses, all those great modulation pedals, some distortions as well, lots of pedals. We got the advertisement for the DC Brick; you can power six pedals at once with that, and the registration. Mail this in,, it’s postage paid, and you’re all set.

    All right. Let’s take a look at the pedal. Of course it comes, just like all of these MXR pedals with the bigger knobs, it comes with a rubber washer that fits over it in case you just want to protect the knob or want to move the knob with your foot while you’re onstage. All right. So this is the pedal. You can see we got one knob, gain, true bypass, 1/4” inputs and outputs, and you also have the input for a 9-volt battery. On the back, you can see these screws. You can take these off and that’s where you put the battery. So, that’s the MXR Micro Amp out of the box.

    All right. We’re back with the MXR Micro Amp. It’s all wired in and ready to go. I’m playing with a Fender American Standard Telecaster plugged into a Marshall JCM2000 half stack, and that’s mic’ed up with an SM57 from Shure. Let’s see what kind of sound we’re getting with just the guitar.

    All right. Let’s bring the Micro Amp in.

    As you can see there’s really not much of a difference at all because it’s a booster pedal. It’s made to give you clean volume just going straight into your amplifier. If we would turn this down, we could...

    ...we could switch between the louder amplifier and also it will attenuate just a little bit or bring down the volume./p>

    So, that’s with it on.

    That’s with it off. Back on.

    And if we bring this up, we can get more volume.

    Back off.

    Back on.

    So it’s really just basically giving you options on stage to have more volume. You can also use it sort of as a distortion pedal where you’re just overdriving your amp more. So, if I have it off right now, we get a clean sound.

    I can turn it on.

    And we’re actually just distorting the preamp on the Marshall. So, we’re getting sort of a distant amplifier distortion, and actually that’s something that I use it for myself. It’s one of my most used pedals on stage. So, thanks for checking the MXR Micro Amp here with us on Gearwire.Com.

    I need awesome gear... I'd like a free gear catalog!
    My opinion is awesome. I'd like to take a gear survey
