B1X FOUR Bass Multi-Effects Processor with Expression Pedal, 70+ Built-in Effects, Amp Modeling, Looper, Rhythm Section, Tuner, Battery Powered

Whoa, if you want some superior bang for your FX pedal bucks, this Zoom B1-4 is the deal of the century! I'm NOT exaggerating. This little jewel is undoubtedly the BEST bass effects pedal I've ever owned or played with. It has everything you'll need, including amp modelling, outstanding compression--the "Glam Comp" setting delivers jaw-dropping sustain, the likes of which I've NEVER heard before--an auto-wah that is a blast to play with, all sorts of nifty filter variations, and even some classic amp tone models right out of the history books. When I first plugged it in and started messing with it, I was astonished by this unit's range and versatility. I could get nearly any tone or amp sound, any kind of filter effect I wanted. It's ridiculously simple to use and has an open, "blank" bank in it that allows you to copy an effect from a different bank into an open slot. It's stupid-easy to set up a series of presets in linear order in the blank bank so that just a touch of your toe cycles quickly to the effect you want. I set mine up with the auto-wah first, then the "hard comp," followed by the "glam comp," with an Ampeg SVT amp model, then a vintage Fender cabinet, leaving four more slots open if I want to add something else, simply by copying the desired patch--a three click operation--into any of the remaining slots. Make a mistake? Easy-peasy: delete it and do it again. Takes less than a minute to reprogram it. Not satisfied with the internal patches? No prob; the unit lets you tweak the parameters to suit your own ears. I didn't get into that; I really liked what I heard. Zoom's engineers really put some serious thought and research into this. There are only two drawbacks: it's made of a relatively lightweight plastic, not aluminum or steel, so it's a wee bit fragile. DON'T drop it! I suggest buying the carrier case that's available. I'm glad I did. It's a hardshell case and protects the unit really well. The other drawback is that some of the patches are a bit...well, WEIRD. One of them is labelled "Explosion." I tried it. Yes, it sounds like someone set off a nuke in the next county. Or a really mean thunderstorm. I dunno, you metal players might find a use for it--but a few oddball patches that I'll never use does not mean a deal-breaker. The price will make your jaw drop, too: around $90. (Zoom might increase the price later. I'm astounded that it's THIS inexpensive.) Shipping will add a bit more and if you get the case, you're looking at a total of around $125 for both. Yes, it comes with a wall-wart that has a nice long cord. All told, the Zoom B1-4 is about HALF the price of a comparable steel or aluminum sheathed unit from any other manufacturer--and it does five times the job. It's clean and quiet enough for recording. Onstage, it sounds frickin' AWESOME. I kick the glam comp on when I hit a low E at the end of a tune and that note will sustain for several minutes. I do NOT exaggerate! No foolin', this is the deal of the century. It's now the ONLY pedal I use onstage for my bass (a Squire Affinity series J-bass with active electronics which is itself an awesome machine.) and I can't see myself using anything else for some time to come. Warning: it will peg the meters on the sound board if you don't give the engineer a heads-up during the sound check. I'm serious. This little beast is POWERFUL.

I play bass for the all pro band Rat Soup so quality sound is a high priority. I typically don't use effects and have always wanted to try them so I purchased this unit. I was not disappointed. A pure signal chain is important to me so I wanted a clean bypass. The bypass signal is very close to the original. So it's not so big of a loss in a live performance, but I would not record with it. As far as tones, there are some great ones and they sound pretty close to the actual stomp boxes. So if you are on a budget and want to try out some different amp tones or effects this is a cool pedal. I love the syth, wah, auto way, and pitch bending effects. For the money this unit is well worth it. Some people complained the wah is not that great, but to me it sounds good. I have a Morley bass wah and this thing is close. As far as usability and gigging . . . I couldn't find a way to bypass a patch other than create a clean patch and jump to that from the patch I want to use. That's fine if you only use one patch, because you'll have to scroll to patches you want to use rather than turn it on or off. You can use the pedal in stomp box mode where you can turn off individual effects with the pedal but not the group. My work around was to use a bypass pedal with this unit. Then I can utilize my pure clean signal and jump to and turn on or off an patch for the whole or part of the song. The looper is cool, but it does not retain the recorded loop after you power down the unit. I wanted to use the loopper to play a sample while playing live, but that's not going to work unless you record the sample right before you play. The tuner is great. So for a practice tool with a tuner and a mini drum machine AND the ability to play with some effects, it's awesome! If you're looking for gigging with great sounds then stick to stomp boxes. But if you want to test out effects and play a few live with a bypass pedal then get this thing. After thinking about it, I changed this from 4 stars to 5 because of the price and what you get!

Update: I've had this for about a month now and this pedal does provide some really good tones but the one I have is susceptible to radio interference when using higher gain settings which is somewhat reminiscent of a scene in the Spinal Tap movie. Cleaner tones are fine but for high gain stuff this may not work for you. I purchased this as a backup to my main multi fx amp modeler and for that purpose it's fine. It is an entry level multi fx/modeler so don't expect Fractal FM9 tones. Overall I'm happy with it and it's good to have in the gig box in case the main unit craps out. Here are some pros, cons, and tips. Pros: Great value. Good selection of effects, amps and cab sims. With a bit of tweaking good tones can be had. Primarily plastic construction but the build quality is good. There is a rhythm function for practice, and a looper as well. The Guitar Lab app make editing presets pretty easy on your PC or Mac. Cons: Most of the presets are set to run into the front of a guitar amp are not going to sound good without changes if you run through a PA or FRFR. Presets have up to 5 effect/amp/cab blocks available and when used as a modeler 2 blocks are going to be used for the amp and cab sim leaving only 3 for effects and such. The user interface on the pedal wasn't intuitive for me so it took some time to figure out. Tips: Download the full manual and the Guitar Lab app from the Zoom website. The included quick start guide just covers the basics. If you use headphones, PA or a full range flat response speaker the "mic" setting on the cab sim blocks must be turned on. Any preset with a cab sim has that setting turned off by default. So to recap, it's a good unit, the price is reasonable and Zoom makes quality stuff.

I wanted a little more spice on the bass and so investigated about bass pedals. This is literally the cheapest, serious looking, one. I checked reviews and decided to go ahead with the purchase. It's great really. It has a looot of effects, you can either use pre-built effects or make your own. I used the free 50-59 slots for my own sounds, there are even some sound effects/processors that don't appear on the stock patches that are very interesting. It also allows to eq (low, mid and high) the output as well as increase volume by 27% (max volume is 127%). I didn't realize after buying but it has an AUX In port, so you can connect your phone on computer and play backing tracks if you desire! The looper and prebuilt drums work great for practicing, the drums sound pretty generic it would definitely be nice to have the chance to upload custom drum patches. I use a micro-usb to power it but it can also run on batteries making it very versatile. All and all I would definitely recommend it. I bought it for $120 and consider it worth it, If on discount to $100 don't think twice (I tried sniping a discount but got impatient hehe) Dark red color is great also.

This is an awesome bass effects unit! Great selection of settings for a variety of pleasing tone variations. Unlike the other brand unit I tried (which had effects so garish it sounded like outer space or special effects), this one actually has presets that make my tone sound better and more musical for jazz, slap, and rock. My favorites so far are JacoBass (fretless emulator), Motown, and the Ampeg amp simulation. Has 5 banks of 10 and the last bank is empty for you to save your own. You can also use “stomp mode” to turn various effects on and off on the fly. Very cool little device!

A ton of very usable presets, more you can create and save..You get really decent sound from most of the effects. Also a drum machine and a looper. Slight learning curve but not too bad. You can change and create your own patches and put your simulated pedals in any order to find what works best for you. I found alot of cool tones and you are able to hear what different effects sound like without buying an expensive pedal first every time. 6 months in...It has a permanent home on my board. It is plastic housing. That's a minor issue for me but I'm really not taking it many places. The value for the money is there so I can absolutely overlook it Haven't had any problems at all. Only wish it was metal. It would feel a bit more sturdy. It definitely needs a dedicated 500 milliamp power supply. Wrong one will cause noise. I get zero noise with the right power supply. I'm very happy with it so far. It does exactly what I need it to do for my bass rig. I absolutely can recommend this to someone who wants to explore the different sounds out there but still wants quality usable sound and some good value for the $$. This is a good one.

I got this nice upgrade after using a less than stellar compression pedal that was fine at home, but horrible on stage. Pros: it’s got lots of power even before it gets plugged into my Peavey Maxx 112amp. You can plug in your phone with a dongle adapter you can get so it has the 35 mm jack again hooked up to the new style iPhone plug adapter to have backing tracks along with your bass. Mine is mixed in tandem with my amp so I can have my IEM as well with my extended IEM connector cable. It sounds like an on stage system for me and is perfect with lots of patches you can have or take away, I use a 750 (ToneHammer simulation) and SVT (simulation) on it quite a bit. It’s not a Stomp by no means, but gets the job done for less money. Cons: It’s very light weight and boomy (rattles the walls and windows) if you live in an apartment like I do with a Karen neighbor upstairs I finally ran off, before deciding to just use it where only I can hear it

What a great little pedal. In a small package, it combines a lot of features: a drum machine, tuner, looper, and very nice selection of effects, amps sims, and miced cab sims. Something I like very much about this pedal - is usability. Which such a huge number of options and features it is easy to make such devices too complicated to use. Not is a case of Zoom B1 Four - the user interface is surprisingly logical, simple and easy-to-use. There are no confusing deep menus, clicking trough endless lists, etc. Everything is just one or two presses away, with options easy to find and understand. Special kudos for a dedicated physical knob controls, which map directly to effects params, eliminating needs to scroll through options just to tweak few params. Another great feature (added in 2.0 software update) is an ability to switch looper between pre-effect and post-effect (previously it was post-only). This allows you to record some riff, put your bass aside, and tweak the sound until you get the desired result having an exact same sound to test it on. Amazingly handly! Battery power and headphones output mean it is an ultimate headphones practice device with a plus of being very portable. All you need it G1 Four, headphones, and bass. You just dial in your favorite amp and cabinet sound, and you get a great bass sound even in headphones. Physically it also looks very tough and sturdy and feels like a quality device, not a plastic toy. 10/10, Amazing product from Zoom

great processor, better if you got an active bass, eats alot of battery though, i use duracell ultras for this processor and it runs out after few practice sessions, however there's an option to plug in a type b cable to make it work, so its ok.

Muy contento con mi pedalera. Tiene muchas ventajas: Es compacta y ligera (del tamaño de mi mano), funciona con pilas AA (incluidas), con conexión USB o por corriente (no incluye eliminador pero yo uso uno de 2da mano y no he tenido problemas). Tiene bastantes efectos y al conectarla al PC se descargan más. El sonido no es pro (obviamente) pero para ser una pedalera económica pues es muy aceptable. Además tiene integrado herramientas como afinador, looper de 30 segundos y caja de ritmos (con un volumen muy alto por cierto; no necesitas baterista jaja). Es fácil de configurar; en la página de Zoom puedes descargar los manuales en Español... eso sí, necesitas tiempo para probar y ajustar los efectos pero la verdad es muy sencillo y entretenido. En conclusión, pues me ahorré una buena lana en pedales individuales de momento. Ya cuando busque algo más profesional (y tenga dinero) pues doy el cambio. La recomiendo ampliamente.

30 yıldır gitar çalıyorum bas gitar tonlar için oldukça güzel yapı olarak plastik metal bir yapıya sahip değil ancak kırılma gibi bir şey olacağını düşünmüyorum USB’yle çalışıyor olması çok büyük bir avantajı kesinlikle tavsiye ederim

Perfection! ⭐️⭐️⭐️⭐️⭐️

I am a beginner and it is very useful for me to listen/know all kinds of tones. It boost my eagerness to practice more.
