With a footcontroller it can be operated in "stomp box" mode too, so instead of changing presets you can kick individual effects on and off.
About units like this in general, I always find it funny when someone evaluates a unit based on factory presets. Have any of you, ever used factory presets ? The thing about the G Major is if you make your own presets and set up just the effects you need, it sounds really good. I have some presets on mine where only delay is employed. Others with a little chorus and verb, but most of the time my wet/dry is set mostly dry, just a hint of an effect for added dimension.
The G Major is a great unit if you are comfrtable with multi effects processors.
a little off topic but.... I played once with another guitarist in a band and he had just discovered MIDI controllable processors.... man he sent me on an anti effects trip for a long time. Thanks to him and his Chorus drenched rhythm sounds, his blatent abuse of multitap delays, flangers swooshing away all the time, I started playing with one efect, my trusty Vox wah, straight into my Mark IV. It was he, with his SICK obsession with overkilling his gadgetry that was a big part in my realizing the joy of playing mostly naked, maybe a little delay on some solos, but even that was at like 20% of the dry signal volume, and thankfully our soundman was competent enough to patch my delay in at the board, so I never even had to activate it!!! In the studio I cannot say how many guitarists come in and act handicapped when I cut their reverb off!!!
Anyhow, sorry about the rant, I love effects as much as every other gear junky..... when used sparingly.
