B1X FOUR Bass Multi-Effects Processor with Expression Pedal

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!

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.

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.

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!

No need for a power cord. Rechargeable lithium batteries are recommended because of their longevity and it powers on only when the bass is plugged in. Easy to navigate the effects and it’s explained well. Great value for the price. Read manual before updating firmware.

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.

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! ⭐️⭐️⭐️⭐️⭐️
