The Marshall JMP-1 is a valve based guitar preamp, offering a single space rack mountable unit for use with electric guitar. It’s great for the home or professional studio owner who doesn’t necessarily want to always set up an amplifier for recording guitars. The unit has two valve tubes (ECC83’s to be exact) inside of it, so you’re getting a pretty realistic sound for something that isn’t actually a traditional amplifier. It’s got ¼” jacks for input and headphones in the front. I’m not really sure what other types of connections it has since the one that we have at the studio where I work is racked up and hooked up to the patch bay already.


UTILIZATION

There’s a whole lot that can be done with the Marshall JMP-1, a lot of which I haven’t even tried to use it for. One of the smaller producer’s suites that we have at the studio complex where I work has one of these in there, and it’s definitely best suited in this sort of setting where you might not be able to use a real amplifier. It’s also great for beefing up tracks that you’ve already recorded with an amp. There are four basic channels in here – two overdrive channels and two clean channels, each with controls for presence, gain, volume, and bass, middle, and treble EQ control, as well as a Bass Shift control which messed with the low end of your signal a bit. Like any digital device, you can store and recall your settings quite easily. I haven’t seen the manual for this, but it would definitely be helpful to have if you can get your hands on it.


SOUNDS

The sound of the Marshall JMP-1 is about as close to a real amplifier sound as you’ll get outside of using a real amp. I’ll always try to get a real amplifier sound when possible, but have been using this here and there if I’m looking to beef up a pre-recorded sound or adding a new part if I’m not able to use the original amplifier I used. I love the versatility that you’re getting with the JMP-1, as it gives you more options than you could get with a traditional amp, and the real valve tubes give it a realistic sound, which isn’t something you can say for most of the units out there like this…


OVERALL OPINION

If you find yourself looking for a device to record guitar directly into your DAW, but don’t want to compromise too much in realistic sound quality, the Marshall JMP-1 is the perfect place to start. I haven’t seen too many other units like this one out there that offer a realistic sound in such a compact box with this amount of flexibility. It’s still not a replacement for a real amplifier, but it’s about as close you’re going to come…
