Get the exact tone you’re looking for, from USA to UK and everything in between.
The conventional three way guitar EQ network, or tone stack (a.k.a. Bass, Middle and Treble), is a key to the characteristic ‘voice’ of traditional guitar amplifiers. Classic amplifier designs have their own versions of this network which leads to their own tonal voicings. The ISF control allows you to infinitely adjust the response of the tone control network between any of the traditional voicings in a way that has never before been possible. In this way you can design your own sound and truly find ‘the sound in your head’.
The patented ISF control allows you to choose the exact tonal signature you prefer. Fully counter clockwise has a more American characteristic with a tight bottomend and more aggressive middle, and fully clockwise has a British characteristic which is more ‘woody’ and less aggressive. This leads to a very familiar, musical response.
What are the benefits of ISF?
- ISF is a passive circuit giving a musical response that is not found in active parametric or ‘contour’ controls.
- The whole tone stack response (i.e. Bass, Middle and Treble) is moved.
- The tone controls remain fully interactive, just like in a regular tone stack.
- The ISF control is continuously variable between all the traditional responses allowing you to effectively design your own sound.
- ISF and ‘the sound in your head’ are only available on Blackstar products.
