I was a bit confused about the tweeter control too
. On and off only means you're probably going to blow a tweeter pretty quick. You really need a separate control. I went from being very anti-tweeter to pro-tweeter once I did a little tweeking. I hope we're both wrong about the tweeter switch, because if that's what it is , I'd leave it off too
.
One of the features they have on this amp is separate inputs for active and passive pickups , and that is a really nice thing, particularly if you are an ABG player.
Overall, I like GK stuff a lot. Very nice sound and the controls make it pretty flexible to fit a lot of different tastes. I'm looking forward to getting my hands on one of these
