Zoom G1X Four Multi Effect-Pedal

I use this at home as my main effects unit. It's usually the only effects unit in my signal chain. Overall I'm very happy with the unit for this purpose.

Pros:
1. It's the same price as a single effect pedal, yet it contains dozens of effects. Most of the effects sound really good. If you want to experiment with lots of effects to find the ideal sound for a song, this is a convenient and cheap way to do it.
2. The build quality is good.
3. The unit doesn't hum or buzz.
4. There's a tuner which appears when the effects are bypassed.
5. There are 3 different ways the unit can be powered: with a micro USB charger, with a standard 9V PSU, or with 4 x AA batteries.

Cons:
1. The looper has 30 seconds of memory, which I find to be insufficient.
2. Changing effects midway through a song is somewhat impractical. It's achievable if you are switching between effects that are stored in adjacent memory slots. Otherwise you will have to keep hitting the "up" or "down" footswitches until you reach the program you want. The foot switches are "up", "down" and "on/off". The up and down switches cycle through the 50 programs.

Minor niggles:
1. It doesn't seem to be possible to use the looper with the effects bypassed.
2. When the effects are bypassed the volume knob becomes a pitch adjustment control for the tuner. However the signal is still affected by the volume setting. You just can't change the volume.
3. Changing the effect parameters is a bit fiddly, but no more than you would expect on a compact multi-effects unit.

The default programs range from the not-so-subtle to the bizarre and amusing. However it's easy to create your own programs. A program can contain up to 5 internal effects. Many of the internal effects are emulations of specific standalone pedals. For example, there are emulations of the Tubescreamer ("TS Drive", Klon ("Gold Drive") and Zendrive. Don't let the eccentric default programs put you off. There are plenty of usable effects in this pedal.

There are additional internal effects that can be loaded onto the unit via the USB port. To this you need to connect the G1X to a PC and run the software that is provided. It would be nicer if all the effects could be loaded on to the device at the same time, as this would remove the need for a PC. I rarely connect the pedal to a PC and hence I'm probably missing out on some useful effects.

For the money, this unit is very good. If the limited amount of looper memory and limited foot controls don't bother you, I think you'll be happy with the G1X Four.

Having had this for several months, I can say it helps out in a lot of different ways. I use it both standalone and in combination after a pedalboard, where I will just load an amp and a cabinet in the unit and then stack it with analog pedal effects.
The built-in tuner is great and prevents the commotion of having a separate tuner pedal. The looper is not the best feature because it is short, but it is enough for me to record the rhythm/chords and check if the scale I'm using for the solo works.
When using it standalone, it would be nice if the amp and cabs do not count in the 5 available effects per preset, but for me 3 effects are usually plenty and not a major drawback.
Finally, the effects are still regularly updated when I plug it into the PC (be careful, only the active/loaded ones get updated) and there is a small community where you can find ready-made patches for this model to experiment with.
All in all, a lot of fun if you have the time to noodle with it.

I'm honestly sorry to give it back. It's got a great looper that can be synchronized with the drums. It even counts 4 bars before starting the looper so you don't have to play the first note and kick the start button simulaniousely. The Looping is perfectly synchronized with the drums then. 30 seconds of looper is not very long though.
BUT: It is by default set to "amp" output mode and it does NOT have a global switch to change to "mixer" or "headphone" mode (!!??). So you have to trigger a cryptic "microphone" feature in the cabinet simulation to get a decent sound when playing via the livingroom stereo or even listening to it via headphones (!?) I mean, you can do that, but you have to do it for EVERY patch you use. Okay, no problem so far, but you need to inform the customers about that. I guess most of the time the device is gonna be uses in a livingroom or with a computer or a DAW or headphones. Not with a "real" cabinet. Learned about that "microphone" mode from the interent.
You can buy it but you need to turn on "microphone" with mixers.

I was looking for a pedal that could help me practice live with a loop pedal, and add several tones. I was looking for an octaver, a noise killer, overdrive, compressor and a tuner. It would cost me at least 250 to have something decent.

For the price this is pretty decent honestly.

Pros:
- Easy to use
- You can play with the numerous effects it has and switch between them, or use up to 5 pedals (as if it was your pedalboard)
- Sound is pretty decent. If you use amp, don't forget to turn off the micro, else it is bad
- Drums and rhytms are helpful and sync with the loop

Cons:
- The loop doesn't allow you to store your recordings
- In the 5 pedals options, the cabinet, amp and expression count to... So if you had them you will only have 2 more options. I think the expression should always work as volume at least.

Anyway it is worth the money.

The G1XFOUR seems to be a direct replacement for the G1Xon. It is a good product, however it seems to be a downgrade in a couple of aspects that are important to me.

You can have 5 effects running at the same time. That sounded fine, but I didn't realise that also includes the amp, cabinet, and volume pedal! If you want to use an amp sim, cab sim and volume pedal, that means you only have 2 slots for other effects. This is a complete downgrade from the previous model which included amp sim and cab sim as one slot, and the volume pedal wasn't listed as an effect and could be used at all times. In the previous model, I could run Compression, chorus, amp + cab, delay, reverb and EQ, and it wouldn't have a problem.

If this doesn't bother you, then I recommend it, as the sounds from this pedal are still great. Unfortunately, I would like more effects to be run at the same time and this just doesn't do it.
