### ⭐⭐⭐⭐⭐ Great Little Machine!
*by  on Reviewed in the United States July 23, 2021*

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.

### ⭐⭐⭐⭐⭐ C-c-combo!
*by  on Reviewed in the United States November 17, 2019*

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 for practice and experimenting, wouldn't use it in a pro setting.
*by  on Reviewed in the United States September 28, 2023*

Cons:1) No bypass. At all. Best you can do is try to dial in a "Clean" patch to switch to (unless you have a separate line selector pedal).2) Noisy when powered unless you use Zoom brand power cord, $20 sold separately, or AA batteries (which it eats up pretty quick). I haven't tried the USB option.3) The sound quality is not good enough for serious live or recording applications, IMO. I found the chorus, octave, and synths surprisingly decent, but everything else was pretty meh and all of the drive/fuzz/distortion stuff painfully bad. I didn't expect much for $99, so it's not heartbreaking.Pros:1) Number of features and sounds. I didn't know which pedal to get next, so I got this to see which effects I enjoyed most. It lets me try just about any combination of effects and how I might incorporate them before I throw down $$$ on a quality single pedal.2) Convenient for rehearsal. I didn't intend to use it for this, but I have very much enjoyed it as a portable practice tool. The drum tracks, battery power, and headphone out make it easy to use.3) Computer interface. Sure, it's not a recording interface, but using the software to manage patches is very helpful and beats menu diving on the pedal every time you want to tweak one of the infinite parameters.I feel like I got my money's worth. It's been a lot of fun. I wouldn't take it to a gig, but I use it almost every day to practice and try out different sounds. I hope this helps you make your decision.
