I did extensive market research before deciding to purchase the GX-100 six months ago. What I can say after six months with the Boss GX-100 is that it is the best value for money in terms of modeler/multifx units currently available on the market. It may not have as many amp models as other modelers, but the ones it does have are more than enough to meet your every need, regardless of the genre of music you play. Especially the 3 X-Amps, which are Boss originals (not simulations of existing amplifiers), give you the feeling of playing through a tube amplifier. It is unnecessary to say anything about the effects, as we are talking about Boss. What impressed me about the GX-100 is how easily and quickly you can create high-quality patches. The color touchscreen definitely helps with this. Personally, I use the GX-100 in manual mode. This means I select the amplifier and cabinet I want, and then assign the various effects I want in my patch (wah, compressor, overdrive, chorus, phaser, delay, reverb, etc.) to the footswitches of the pedalboard, and I activate or deactivate them according to the needs of the song I am playing, as if I had a regular analog pedalboard at my feet. In terms of construction, the GX-100 is built like a tank. You can use it comfortably and fearlessly in live environments. I have used the GX-100 with headphones, connected to the fx return of my amplifier, and as a sound card for recordings, and the sound has always been amazing and a source of inspiration.
