I spent hours trying to get any of the Zoom Guitar Lab software to work. Trying to get it connected to the mobile app was a no go & the PC software does not support this specific model at all. Manually configuring a few patches was complicated & tedious too.So why the two stars??? The out of the box patches were good (lots of them) and the drums and looper were solid. However, for the drums and/or looper to work, they must be added to the existing patch ...and each takes up a slot. So if you use all 6 slots in a patch, you'll have to replace 2 slots to use both the drums and looper.I'm a fan of Zoom products, but with no software support and clunky user interface, the Zoom G2X just can't compete with similar effects pedals.I now understand why it was on sale, but should have done more research on it.For now, I'll be sticking with my Zoom MS-50G and Donner Circle looper, but I do have my eye on the Zoom G6 (which appears to support Zoom Guitar Lab for PC).

Has two output modes: guitar amp and line-out. My ears tell me that guitar amp mode is basically line-out mode with treble frequencies reduced so that it doesn't sound harsh via amp (because typical guitar amp raises the treble frequencies centered around 3200-4000 Hz). I am mostly using this to go live to the PA system; but I have also played around sending the signal to the amps available in the jam room.The unit sounds awesomely close to high quality recordings that we hear. Most of the amp models are great and sound very close to originals (e.g. Marshall JCM 800, Marshall Plexi, Mesa Rectifier), the amp model come with their own cabinet impulse response, so you cannot change it. But quite frankly since the unit sounds so close to the professionally recorded amps, I don't see any reason to get into the complication of loading external IRs and then playing around with which sounds best with which amp. If you plug into your amp, do remember to chose the "guitar amp" option otherwise you will end up with harsh trebly tone. While high gain sounds are great, so are the low gain and medium gain tones - this is an area where most modelers fail. AND you can roll of your guitar volume to get a cleaner tone without sacrificing the tone! This functionality is exactly like analog gear (dare I say better than most diode and transistor/FET based pedals).The effects are also great, pedal functions just the way you would expect it to. One "con" I could say is that pedal functionality is "limited" to only volume, wah (3 different types), pitch shift, rotary speakers. Perhaps there could've been expression pedal for phaser, chorus, flanger etc. (Edit, this has been take care in the recent update, there is expression pedal for modulating these effects).Another great point in Zoom is that you can arrange any effect, amp, pedal, anything in any order that you desire (many other processors have a fixed sequence that you must follow).The inputs are 1/4" socket for guitar-in and 1/8" socket for stereo line-in for play along! That is a blessing since who uses phone/laptop/handheld device with 1/4" cable? A very well thought of functionality by Zoom.Similarly, output is 1/4" left and right, as well as 1/8" headphone! Another mark of thoughtfulness by Zoom, since who uses 1/4" jack for earphones?Can be powered via 9V adapter (supplied in the box), or with any USB C-type connecter (blessing, you can carry a battery bank and connect it!). In my opinion this is as good as AA battery support (which this Zoom unit does not provide) perhaps better since USB-C type battery bank could be 10-20,000 mAh - show me a Zinc chloride or Alkaline battery with that much backup!Four foot-switches + Four direction switches (which can be operated by foot but with some inconvenience) = great flexibility in live mode.Many people say black and white screen is not as good as colored screen, and doesn't have touchscreen. I say, it may not matter to most guitarists playing, as long as you can read the display easily while playing live. Zoom hasn't released any desktop app for this, so it could be an inconvenience to program the unit by using the switches and knobs. I have yet to try out the android app.The closest competitor to this pedal would be Valeton GP100, Nux MG300, Mooer GE150, Harley Benton DNAfx GiT, Nux MG400, Boss GT1. Nux MG400 and Zoom G2x Four are the best sounding of the lot.Please spend some time listening to sound samples on Youtube, and decide for yourself.EDIT: OK, I guess the Zoom folks read this review :-) The new update adds a few more effects and the best part is that they can be assigned to the pedal (yes, stuff like pedal modulated chorus effect).

La nueva forma de organizar los presets y los botones de navegación accionables con el pie, son una buena mejora para su uso en directo.Le falta bastante capacidad de procesamiento... muchas veces no es capaz de utilizar los 6 slots de efecto disponibles a la vez.La app me funcionó un par de veces y después de eso, nunca más la pude volver a conectar.Entonces, si deseas adquirirla, descarta su uso a través del celular. Serán más disgustos que satisfacciones. Toca hacer los ajustes a la antigüita, presionando directamente los botones en la pedalera.Relación costo beneficio bastante buena, ya que actualmente está más barata que como la conseguí (aprox. 4000 $Mx... hoy abr 24, $3237Mx). Obtienes muchísimo por ese dinero.Pero vengo de la G3 original... que daba mucho más sin reventarte la cartera.En resumenPros: Buena compra, buenos sonidos y relativamente fácil de usar en directo.Contras: Difícil de editar los sonidos. Al no servir la App, olvídate de descargar presets hechos por otros.PDLe tengo el ojo echado a la G11, pero se me hace muy gigante y le sobra el pedal de expresión.Sería bueno que sacaran una versión al estilo Mooer G300 lite

I decided that I wanted to upgrade from my Zoom G1X Four processor. I wanted something with foot-switches and more sounds available. After lots of research, it came down to the Zoom G2X Four. This thing sounds flat out amazing. It’s borderline professional and has recording capabilities, which is really cool to me. I’ve only recorded on it a couple times, but it sounds really clear. The user interface, like a lot of Zoom processors, is a little difficult to understand, but once you learn it really well, you won’t look back.I bought it to play lead guitar at my church. I was able to make a pretty good sounding AC30 patch, a solo boost for instrumentals, as well as a Swell patch. The foot switches make it a lot easier to use than the Zoom G1X Four. I also LOVE the tape tempo availability; it makes working with delay so much easier. The tuner is also very accurate.My main issue is the user interface.

I already had the G1X4, and liked that. The G2X4 has an insane amount of guitar effects, more than I'll ever use, but it was on sale, so I bit. I will be tweaking this for the rest of my life, I think. My one minor critique is that you have to load the looper and rhythm track to each preset, rather than having a standalone looper function, so you can only loop the preset you're currently working with. You can't mix different presets in the loop. You can add and subtract effects within each preset, but you can't exit one preset and switch to another, and maintain the loop track. Aside from that, it more than met my expectations.

With a price point like this... how could you go wrong? If you were curious about the possibility of one day replacing your pedals with one unit, but don't want spend a ton of $$$ on a Helix or Quad Cortex to find out whether you like it or not... This is the product to dip your toes into first. I love it! For me, it was an easy purchase... I could either choose to buy ANOTHER pedal or I could give this a shot. And I'm glad I did, I now have access to endless possibilities of tones & effects. Just FYI, if you plan on spending the 💰 on one of the more expensive brands mentioned above... I have it from several sources to go with the Quad Cortex 😉 Also, it does work with an acoustic guitar as well, but how many of the preloads that work will depend on your guitar and pickup. I hope this helps!
