"Great bass effects pedal-if you know what you are getting!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I see 2 low star reviewers from the person pulling the rating down for this. It's a shame because this is an amazing product, and even though I bought mine from another store, I'm looking for in-stock recommendations for my bass player friends. I bought the Zoom B1X Four, which is the version that has the built-in expression pedal. I have used this with both a 4 string fretless bass with passive budget pickup and also a 5 string fretted bass with active preamp. Both sound amazing through it, so rich and full, with great articulation and low noise.To put it in perspective, here is what you get for about the cost of 2 sets of decent bass guitar strings:A portable, light weight battery powered headphone amp with aux-in and built-in looper and drum track playback that has a variety of bass amp sounds, compression, eq, distortion, fuzz, phaser, chorus, delay, reverb and more. If some says the sounds are "uninspired", seriously...either learn how to use the device and make your own presets or look to other gear in your signal path for the problem. The creative possibilities with creating your own patches far exceeds what 3 pedals could ever give you (as a reviewer claimed). To say that 3 Behringer pedals can compete with this is an absolute joke! But I will explain how 3 standard effects pedals MIGHT be a better choice for you:1. If you need to perform live and turn specific effects on and off during a song. For example, to turn a phaser on for a section and then turn read more it off and turn on a reverb. The reason this isn't great with this device is that there aren't dedicated footswitches for effect like the larger, more expensive multi-effects units. What you would have to do is either bend down and press one of the 5 small buttons (or have it on a stand or table) OR create your own patches ahead of time that you could easily swap between using one of the 2 large footswitches.2. If you have an amp sound you love and don't know much about live sound or recording and just have a sound engineer put a mic in front of your amp. Then yeah, maybe forget the technology and learning and just stick an effects pedal or 2 in front of your amp.3. If you struggle with technology or don't want to read manuals or watch videos for an hour or 2 to learn how to use your gear. BUT HERE IS WHY YOU MIGHT WANT THIS:1. You need a solution for practicing without disturbing others. The headphone jack, looper, and aux-in and built-in drum tracks in different styles with adjustable tempo are ideal for this! Way better than using a metronome.2. You need something portable and easy to travel with. Having optional battery power with commons aa rechargeables means I can practice with headphones on the edge of my bed or during a break at the office, or outside in the sun in a park or backyard.3. You have an interest in exploring different effect sounds, but can't justify the cost of buying a lot of different pedals, that may or may not be what you hoped or work well together.4. You send your bass direct to a PA system rather than a bass amp. The optional bass amp models are versatile. I found 2 I really like, one for a more clean, mellow sound and one for higher energy loud bass. If you have an amp you already love, then you don't have to use the amp modeler sounds, and can just free your 5 effect slots for effects only.Two final notes:1. With the free Zoom software, you can add or subtract effect sounds from the internal memory and also manage your custom patches (saveable presets of effect pedal combinations).2. I'm glad I got the version with the expression pedal. It is not possible to plug in an external expression pedal unfortunately. One thing I'm unhappy about is that unlike every other multi-effect unit with expression pedal I've had, there is no way to program what the pedal controls, besides the pedal-specific presets. For example, if you wanted to control the speed, depth, and mix of a phaser with the pedal, you can't do it. You have to select a effect designed to pair a phaser with the pedal and it will have whatever parameter Zoom has decided for you. This does make using the device much simpler, but only in exchange for custom control. However, there are enough pedal-specific effects on board that it still makes having it worth it, unless you use an additional volume pedal and wah pedal.
