Boss GT-1B Bass Multi-FX Pedal

I use this at home with headphones so far. In this aspect, the pre-amp module is perfect and works much better then most pedals I've tested so far.
I have also used it with a 2x10" GK amp. It sounds very nice, especially the clean sound, which is important for me. The clean sound is good and it's so easy to program it on spot that you can actually tune it just before playing some songs. The presets, despite being high on outputs (usually all pedals are), are very well structured, which makes it easy to find nice sounds.
Best feature for me: I load it in a backpack, together with energy supply, cables and so on and it weights in total less than 2 kg. Love it!
I would definitely recommend it if you're looking for a small and easy to carry pedal that can handle small gigs.

This bass pedal is quite versitile, and has been a lot of fun to use. The preamps, a couple of the mod FX, and the distortion sound good for what they are, and it's portable enough for me to bring basically everywhere I take my main bass (a squier CV jazz). For a pretty cheap multiFX unit, I am satisfied, but it's not a rig replacement nor a good tool to use to track bass, not that I really expected it to be.

I have been using the unit for a while now, predominantly as a practice preamp, but also as an audio interface (I don't have much gear at home to record with) and sometimes I take the pedal with me to rehearsal and performances. To start, the buildquality and handling are fine. A lot of plastic, but it's high quality. The interface is intuitive and the device has a nice formfactor, but the expression pedal has this weird creak when I put force on it sometimes, which makes me think that I have broken it, yet it still works. In addition, one of the rubber feet seem to be shorter than the others, so I glued a small piece of cardboard to that foot and now it doesn't wobble. I have heavily used it for a long time and it still works perfectly, so I am satisfied with the quality.

As a practice preamp and creativity booster it's a lot of fun. I like messing around with the FX and crafting tones that inspire me to create more, but for actual (amateur) recording, the sound is not sufficient for me. While the dynamics FX and most of the preamps are useful, a LOT of the modulation FX, gimmicky and cut down boss FX, enhancing settings, delays and reverbs are subpar. I personally record more experimental bass focussed music, and while playing with the FX inspires me, listening back the playing it all sounds toyish and wrong. I have to do a lot of postprocessing work to make the takes sound nice, because weird highs and overcompression (even without any dynamics FX enabled) are present. For more serious creative work, it started to show it's limitations. To make it worse, the looping is not good. The looping time is so short (by design), that I find myself running out of bars often, and the lack of an undo function make on the fly fun more frustrating.

All in all, it's a convenient and cheap multifx unit that can be used in amateur settings for rehearsal, live performance, and if you don't mind some of the soundquirks, even recording. I liked it, it's cheap and helped me develop as a musician, but me, I'm seeking an alternative for recording and composition, because this unit does not deliver on those fronts.

Let me start by saying that I have only begun to scratch the surface of the GT-1B so my comments will primarily reflect such. I have used this pedal to explore a wide range of sounds that, with the 99 presets alone will have you bouncing around in all sorts of directions musically for countless hours (one year later and I am still in the exploratory phase). I am using it in conjunction with my first bass purchase, a Fender PJ Precision Deluxe Special. From 60s P to 70s R&B to Blues to Reggae, to a host of Synth and distortion sounds and even an Organ replication, this thing can do it all. And with a simple connection to a computer you can access the very user-friendly software and expand or dial-in whatever sound you choose. Not to mention, once you begin the process of creating your own tones (which has a somewhat uphill learning curve) you'll spend months and months and more on your journey to find the sounds that feel most at home to your style(s) of music.
But what makes this pedal so cool are its amazing features. I plug my PC, mobile (for music play-through) and headphones into this thing and can play basically anytime, anywhere (due to the battery option). I would highly recommend you spend the extra few bucks and purchase the Boss AC adapter to avoid any noise distortion from an after-market plug and to not waste money on batteries when playing at home or near an outlet. You can of course also run this pedal to your amp and either play audio out or through your headphones to take your sound pleasure to the next level.
In short, this is a terrific product for home and practice use and several of the settings (but certainly not all) can also be used for professional use. Also, the built-in tuner although criticized by some as jumpy, actually will dial you in perfectly, particularly when working on lining up intonation and octave tuning. This pedal is also rock solid sturdy and again very portable.
If versatility, great sound production and the ability to have fun anytime, anywhere is your thing, then this is the pedal for you. Last thing, you won't find a better place in Europe to purchase your music stuff than Thomann. Service, packaging and shipping are always top flight.
Get this pedal. You will not be disappointed.

The Boss GT-1B was my first pedal, and I bought it with the expectation of a simple, convenient setup that would allow me to plug in my instrument, practice anytime using headphones, and not disturb anyone in the house. It delivered exactly what I was hoping for.

When it comes to features, I’m satisfied. After spending some time with it, I was able to achieve some really nice tones. The only issue I ran into is that the sound you create while listening through headphones doesn’t always translate the same when you switch to speakers or other output sources. So, some adjustments are necessary to get the sound to match what you’re hearing in your headphones.

Other than that, the pedal is well-designed, easy to use, and simple to learn. It serves its purpose perfectly, and the money I spent on it feels well worth it. I would definitely recommend the Boss GT-1B for anyone looking for a reliable, user-friendly pedal for practice and performance.

It sounds better than any VST and great for home practice as well as for rehearsal and gigging
Sound banks are good enough and easy adjustable
Some default presets might sound weird or raw but I don't mind (probably I will find out how to cook them later) because I took this thing to set up my own
Outputs cover all possible situations I can imagine
USB connection is also great, and I know that I will spend many many hours experimenting with community presets or setting my presets on it's software
Build quality is solid, and I can't complain about this purchase at all
The only thing is the original power supply adaptor which is supposed to be bought in addition
To sum up, I received this processor recently so there are still a lot of things to explore though I'm already very happy with it
