Jim Dunlop Electric Guitar Effects (11401000001)

When I hear live bands and the guitar player takes a lead I want to hear it LOUD AND CLEAR but that is rarely the case. Oh, yeah, the band might be loud but it's not the volume that matters, it's the difference between the band and the soloist that matters; the ability of the lead to stand out in front. I notice very little difference between a player's volume when they're playing rhythm and when they're playing lead. Some of that may be their own lack of understanding but if any of it is due to electronics, the problem is OVER. The MXR MC-401 BOOST/LINE DRIVER is a stunning piece of equipment. In the off position it is a clean, true by-pass, just passing your existing signal through without any coloring or distraction. In the on position it gives you a clean, uncolored signal boost, able to add up to +20db with the click of a push button. The lone dial on the unit is variable from 0db to +20db which means that whatever volume you are at, the MC-401 will raise the volume instantly, when engaged, the number of plus db you have dialed in. (Your amp must have the ability to handle the increase. It's like an instant volume dial.) After experimenting slightly at rehearsal I got the general feel of this thing but when I actually used it at a gig, HOLY COW!!!!! This thing is GREAT! Small, compact, rugged as all MXR, simple, and EFFECTIVE. Powered off my existing pedal board power supply (typical 9v) my leads were instantly OUT IN FRONT the way leads sound on recordings. And since it varies from 0db up, it is effective in any size room at any volume. The pedal doesn't care what volume you're at - super loud or super soft - it just does its thing: It makes you louder when it's on compared to when it's off and the amount is consistent with how you set the db boost dial. Also works off 9v battery. Bright blue display light signals when unit is engaged. At $100 or less this pedal is indispensable and virtually priceless!

After much research into all sorts of clean boost options, I went with the MC401 MXR Boost/Line Driver. My decision was partially based on other reviews, partially on my experience with other MXR pedals, (Carbon Copy Delay and Super Comp compressor) which I've found offer great tone, solid build, and great mid-priced value.My only complaint is the placement of the DC power jack, which is adjacent to the signal input jack on the right side of the pedal. (I use both Hosa and Planet Waves right-angle 6-inch patch cables, the Planet Waves fit, the Hosa doesn't.) Easy enough to deal with: Just make sure your input jack is relatively small. (This is so with my other MXR's, so I was prepared.)I'm playing through a late '70's Fender Twin Reverb, which is legendary for it's big, clean sound - and just wanted a simple single-knob clean boost for leads. This pedal kicks up the volume with no apparent loss or coloring of tone - just more of whatever I've put in front of it. The Boost/Line Driver is the currently the last thing my signal is going through before hitting the amp, which allows me to keep the outputs on my other pedals - which are very few - at relatively low levels.Bottom line: One nice clean boost and one very happy guitar player!

I needed a transparent buffer at the end of my bass pedalboard. I did some research and for the money this seemed to be exactly what I needed. It is a great addition and is completely clean and just boosts and does not change or color your tone.) It has a high quality line buffer so I have a solid signal throughout the chain. It does exactly what it's supposed to do.I'm sure there is something more expensive or higher end out there. This is good value for the money. That being said it does it very well for what I need. I'm very happy with it.

I play an amplified upright acoustic bass and an electric upright solid-body bass. I bought this Jim Dunlop MC401 MXR because I have a few bass solos that can't be heard above the other players unless I boost volume, which was hard to do by reaching for the volume knob on my preamp or amp with my hand. This stomp box lets me instantly add a pre-selected amount of volume boost only--no goofy effects, no hum, no extraneous sounds at all. Of course, when the solo is over, another click with my foot drops the boost. This thing sounds completely transparent when it's off, and completely natural when it's on. For my purposes, a boost of five decibels out of the 20 that this device permits seems to be enough. Naturally, you have to have left some head room available in your amp otherwise you won't hear any volume change or you'll get distortion or both, but that should be obvious--it's just like turning your amp up, except with your foot.The MC401 runs on a 9-volt battery, but I also separately ordered the Dunlop ECB003 AC adapter, which is also available at Amazon. I checked the Jim Dunlop website and in its FACs it specifically recommends staying with the same voltage adapter, so I did not order the ECB004, which is an 18-volt model. The ECB003 adapter works perfectly and seems completely silent.The MC401 is compacl, but it's heavily-constructed so it stays put. The stomp switch itself appears to be made of good steel, as is the case itself. Everything is solid as a rock. I don't see how it could be better. Perfect.

Excelente producto, llego bien empacado como debería ser, de calidad y muy buena presentación, se demoró mas de lo estimado pero llego sin inconvenientes, super recomendado

Hooked into the direct-to-amp signal path, this pedal gives a massive boost when running a clean signal. However, the boost is very, very minimal when applied to a hi-gain signal. I found the best way to get a lead boost for gain is to run it through the effects loop of my amp. When doing so, the effects loop input and output signals need to be adjusted properly to minimize 'tone suck' from the dry signal. It took about three minutes of playing with the effects loop settings and now we are golden! Either way, there is a fairly significant 'coloring' of the tone so I'm deducting one star for that. Again, this is more noticeable on a gain signal. The clean signal is less affected.

Very simple line driver for solo volume boost. It’s quiet and doesn’t alter your tone. Very happy with this device.

Lo sto usando per il set acustico e, a mio avviso, è il miglior Clean Boost sul mercato per il prezzo, il suono rimane bello e nitido, senza variazioni nell'eq.

Great sounding clean boost,flawless construction.

Nada que ver con el micro amp este booster no te mueve tu eq es trasparente depende la plskcion te da mas gain o volumen aparte de una estica impresionante

Need that extra boost for solos? Then unless you are lucky enough to own a Mesa 5-50 Express, or seriously rich and have the mark 5 (ya lucky ) then this is solves all issues. Forget switching channel just set the know to around 10 o clock, and job done

Excelente producto, todo lo que especifico llego en excelente estado y puntualidad
