I've had my mind on this amp since I first plugged into a few months ago at my favorite local shop. The Electro King is a copy of a late '50's Gibson GA-40. It's 15 watts driven by two 6V6's through a 12" Jensen Alnico speaker. I love the way it breaks up almost immediately, especially with humbuckers. I mean there is like zero headroom for cleans out of this thing. It doesn't really even come on until about 2 on the dial and it's clean to about 2.5. At 3 it starts to break up and by 3.5 it's completely overdriven. You can get a touch more clean out of it through the second input or on the trem input but not much. I've been using an A/B switch to pair it with my Regal. They work well together, Regal for cleans and the Electro King for overdrive. The overdrive is real dirty in general and after about 6 on the dial it starts to introduce a bit of a high end treble buzz that sounds pretty cool when playing leads. You can tone this back but turning the voicing dial more toward the bass side instead of treble but I like the effect. I find the sweetest tone for rythym to be right around 5. It stays nice and fat at that volume but still has enough overdrive for my liking. Another thing I like to do is to keep the dial at around 3 and play lightly on the strings it gives some nice cleans but when you really dig into the strings and you get the breakup. Reminds me of a Marshall Bluesbreaker in that way. The trem is pretty over the top, even more so than on my Regal. If you crank it all the way up it almost sounds as if the amp is turning itself on and off. At lower more useable settings it seems to be very organic, like your riding a wave of sound. Typically I only use trem on cleans so I'm not sure how much I'll use it on this amp. I'm not sure what else to say really, it's a cool amp and I'm glad to have it in my collection.
