I just got home from church and while I was their I was making some tweaks to my amps (Blackstar HT40) EQ. One thing I really noticed while setting the EQ for the dirt channel was how much mid emphasis their was and kept trying to dial some of it out and clear it up and ended up settling with the mid knob at 2. Does anybody else here feel the same way the midrange is very prominent?
Also I was messing around with the ISF (Infinite Shape Feature) knob trying to get a feel for what exactly it does to your sound. Blackstar says it basically makes your amp sound more American or British depending on which side you throw it on but it only works on the dirty channel and after messing with it for close to an hour they are absolutely right but it's weird how they did it.
Once you get the EQ (BMT) where you want them you can turn the ISF knob to fine tune and give you the characteristics you want but it's strange how it works because it changes the amps character but in a way it still stays the same.
From my experience when you turn it left to the American side it changes the distortions character and makes it a bit more aggressive, and more modern sounding, along with emphasizing the bass and treble and scooping out a bit of the midrange but it's not a huge change, just enough to give it that type of character if thats what you want.
Turning it to the right gives you a british amps character which has a different distortion sound from the american voicing. It is not as aggressive and a bit more round all over and you could even say it has a "woody" sound to it's distortion. The bass is rolled off a bit and treble subdued a bit and the mids are little more prominent but again it's not a huge change but you can definitely notice the difference between the two sides when the knob is turned all the way in either direction.
Overall I choose to leave it in the middle at 12:00 because to me it sounds the best their. Overall the knob is very useful especially if your going for a certain tone or genre of of music. The whole range of the knob is useable but I like it either all the way left or right or at 12:00.
