A great little multi-effects/modeling pedal for the price!
The Zoom G1on multi-effects/modeling stompbox is a surprisingly capable device that's made all the more compelling a value for its ability to run for hours on 4 AA batteries. It has its limitations, of course, but you can find it used or refurbished all over eBay for around $50 shipped - and that's a steal by any yardstick!
To begin with, the 2.0 BIOS update gives you 100 factory patches to start with. As with most multi-effects/modeling devices, many of these are near-duplicates and/or near-useless for most purposes - but you can freely modify to or completely replace them with custom patches that better suit your needs with a littel effort.
Here's where a free, third-party patch librarian called zoomlib is nearly indispensible. It's available for Windows or Mac computers, and it allows you to backup patches, change their order, add multiple copies of the same patch and so forth. Just search for zoomlib and it'll show up in the top few results in any search engine (eBay frowns on external links in these reviews, or I'd just post it here).
That last capability - putting multiple copies of the same patch in consecutive slots is the key to getting the most out of the G1on and its slightly-bigger brother the G1Xon (which features an expression pedal, but is otherwise the same device). Both pedals have zero in the way of real-time control over parameters like distortion, echo, modulation (chorus, flange, etc.). The way to deal with that is to set up consecutively-numbered patches that are identical to begin with. Then add a distortion, for instance, to the second iteration, so that, when you're actually using the device, you can, in effect, kick in distortion without otherwise altering your sound simply by stomping the UP footswitch, then kick it off at the end of your solo by stomping the DOWN switch. For a different basic patch, do the same kind of thing to add gain or effects to it - and so on.
Editing patches is kind of a pain. You HAVE to do it via the pedal's menus, because there's no patch editing software available for these guys (zoomlib is strictly limited to backing up, re-ordering, and adding already-edited patches). You start with an amp/speaker model, then add effects or sound-shaping modules to the chain. (Note that some effects are CPU-intensive, which limits how many you can have in a single chain before the device hits a wall. It will, however, tell you when you try to exceed its processing power - and refuse to let you add that effect, etc. to the current patch's chain.) Each amp model and device has controls for things like gain, depth, tone, etc. Which controls are avaiable depends on the device that's being modeled (so, for instance, the OD-250 model has only tone and drive, whereas the Rat model has 3 other dials to play with). You can usually get away with up to 4 devices (including the amp/speaker model you start with) in a chain, but 5 is really pushing it.
To use zoomlib (or to upgrade the BIOS), you'll need a USB 2.0 male to USB-mini female cable, which is not included. Nor is an external power supply (I recommend the Snark for that. It's inexpensive, very quiet, and has enough power to run three stompboxes on a daisy-chain cable.) 4 AA batteries ARE included, which is a nice extra. And the fact that these guys will run on batteries for 8 hours or so is really nice, because that means you don't have to drag along an AC adapter to lose or break. (These units will also run off of USB power from your laptop or desktop computer, so there's that, too.)
Note that you have to plug a 1/" cable into the input to turn the unit on. The 1/4" output jack - which is confgurable for either line- or instrument-level output - doubles as a stereo headphone jack, as well (and it's auto-sensing, so you don't have to do any special configuration just to use it as a headphone amplifier). Make sure you adjust the system settings for alkaline or rechargeable Li-ON batteries, depending on which you use (the unit comes with 4 alkaline AA's).
This is a great little stick-it-in-your-bag-and-go device for jams, although you could actually use it for performances, as long as you put some planning into setting up and sequencing your patches ahead of time. It is NOT as capable or as faithful at modeling as something like a Line 6 POD-HD, or a Digitech RP1000 - but it's just a fraction of the cost of those pedals, so you really can't complain about its limitations in comparison to those excellent, professional-quality, EXPENSIVE devices.
I'm very happy with mine. Chances are, if you buy one knowing its limitations in advance, you will be just as happy with yours ...
