Many of us, including myself, are trying to find a good combo or rig to suit our playing styles and venues. Some people are lucky/smart and find their favourites in no time, but probably most of us go through hell and high water before finding what we like. So go ahead and list the biggest disappointments you've experienced when trying out different heads, cabs, combos and/or rigs. If you could also mention for what use you were looking for the product and why you think it was such a flop, maybe we could learn something... Lets spill the dirt.
