i've always assumed that low input jacks referred to single coils, while high input meant humbuckers. now i'm thinking that low input is a dry signal, while high is through a boost? is this wrong? if i have an amp w/ only one input, can it be optimized for high or low input? it seems that the best way is to start with one configuration, then use a pedal to bring it up to spec of the other. any ideas?
