I've been an user of multis for ever, I have owned maybe 2 dozens of them.Do you think that it's good right out of the box with out tweaking? I do notice that the preset patches are pretty level volume wise which has always been a gripe with other pedals.
I always consider them as separate pedals put together. Never ever rely on patches unless you made them yourself.
This way if an adjustment is needed you know what to change.
Another issue is that patches are meant to be flashy. This is why they are always set way above unity gain, because gain sounds good. It is also why they usually sound great solo in the shop or bedroom but get lost in the mix.
