Boss GX-100

This unit is incredible for the price. I remember most modelling pedals being cheap and beginner level about a decade ago but it's not the case these days. The GX is very well built, heavier than I expected. Every switch is fully programmable and customizable, per patch. Can also send MIDI CCs per switch, so I've mapped some switches in Ableton Live for scene scrolling and launching. The display is great but the unit can be used without heavily relying on the touch screen and instead by using buttons and encoders. The rotary encoders feel great, are not cheap, are indented and 'click in'. The four rotaries below the display can be mapped to any parameter within the patch for quick access. Very logical and straightforward UI, doesn't take long to learn. The blocks (hexagons) are color coded by category. No latency to speak of when playing and switching patches. A separately sold Bluetooth module can be purchased for editing of patches on an iPad or phone, so you don't have to crouch constantly. I've literally recreated my own rig (amp, stompboxes) on the GX-100 and couldn't believe how good it sounded and responded to touch, so I'm selling everything and keeping this as my main amp/effects unit. Near-infinite possibilities in patching, routing and assigns, including the expression pedal, which has good travel and sensitivity. Time based effects such as delays can be tempo synced to an incoming MIDI clock, or you can set the GX to be a master clock and send a MIDI Start/Stop from one of the switches. BPM can be set per patch also. The looper module seems to be basic because obviously Boss won't eat into its own looper market with the GX. I couldn't find a way to sync the looper to the internal or external clock or quantize the bars, so it's just a basic looper for quick ideas, with you as the reference in timing. Maybe it'll get better with an update but it's just a minor con for me.
Overall, I'm very impressed with the GX-100 and would recommend it if you're in the market for a swiss army knife of a modeller on a moderate budget.

Just jumped into GX100 coming from the old GT3. Sound is awesome, easy of use is absolutely stunning (wouldn't go for the 1000 until I can afford a sound engineer), quality is perfect but Slicer has disappeared from it... Obviously if you were not using it you won't notice but if you were you will have to solve it by buying it or other pedals and plugging them via send-return. In any case worth to recommend an spectacular multi-effect pedalboard with a professional sound and full ability for setting up all kind of parameters per effect, all kind of possibilities when working on manual mode (1 pedal may be assigned to start 1, 2 or n effects if you wish), you may set up an effect and create copies for each of your guitars. A pleasure to work with such technology.

After using a pedalboard with analog pedals for years, I've decided to go towards the digital way, since the stages in the halls I play have limited space, and placing & miking an amp/pedal board is pretty hard. So after looking various alternatives, I chose Boss GX-100. After using it in couple of gigs, here are my thoughts:
Pros
+ Sturdy chassis, I mean it is strong, no plastics
+ I liked the sounds of the amps and pedals, it is Bossy :)
+ Many outputs inc. send/return, controls. You can connect it anyway you like
+ It's software and extra BT dongle helps you connect to computers and phones
+ The dimensions are good for compact floor space
+ It has a touch screen while you still can use the knobs,
+ Broad programming possibilities, you can do almost anything you like (within the units capabilities)

Cons
- The touch screen is not the best amongst rivals I presume (still, it works)
- I would like to see an XLR out port
- As valid for almost all digital units, the factory presets are useless to me

To sum up, I liked the unit and will keep it using in my gigs. I've created my own patches from scratch (around 25) to use on stage by directly connecting it to the FoH mixer.
