Free The Tone Custom Series HB-2 Heat Blaster Overdrive Pedal


The Heat Blaster is a modern American-style distortion pedal from Free The Tone. It's made to emulate the tonal characteristic and playing dynamic of a modern high-gain tube amp. So it will give you all of the saturated tube-style distortion that you'd expect but it will also clean up when you roll the volume off of your guitar.

Low Cut and Hi Cut Toggles

The Low cut and Hi Cut toggles are really important because when you're playing hard rock or styles that require lots of gain, you need to control any loose low end and make sure the top-end isn't too harsh. So with both of these controls, you can tailor the frequency response of the pedal. It makes it a breeze to tighten up the low end and the hi cut will round out the treble of the pedal.

Here's what Free The Tone say about the HB-2

The FREE THNE TONE HB-2 HEAT BLASTER features a modern distortion sound. With the HI CUT and LOW CUT switches, you can create variations in sound.

The HI CUT switch cuts the presence range to create a mellow sound that can still cut through. By turning the TONE knob clockwise with the HI CUT switch activated, a mellow sound that remains clear can be obtained. This is especially suitable for guitar solos.

The LOW CUT switch cuts low frequencies. A combination of the bass and drums in the low frequency range is important for a band sound. The LOW CUT switch allows you to trim the low end that cannot be adjusted by an amplifier’s tone circuit. Effect on/off switching uses a special true-bypass method in which the signal goes through only one line in the switch in Bypass mode.


  • High-gain distortion just like that created by a modern tube amplifier.
  • The HI CUT and LOW CUT switches are implemented to enable many variations in sound.
  • Special true-bypass method in which the signal goes through only one line when the switch is in Bypass mode.
  • Exceptional sound stability by using long-life high reliability components


One morning I awoke with a great distortion sound in my mind. The sound was surprisingly distinct and clear, and similar to that of a modern high-gain tube amp. The HEAT BLASTER was born from the sonic image I awoke with that morning. But I had to get to work immediately in order to turn the mental image into actual sound before it changed or faded away. It was a race against time. I began mentally designing the circuitry on my way to the lab, and was ready to start building by the time I got there. All previous plans and appointments for that day were postponed while I set to work, and after about 6 hours of non-stop prototyping and testing I had a sample that delivered the required sound (definitely a speed record). The sound was almost exactly as I had imagined it. But that was all I could do in one day. I was exhausted. But I had my circuit, even though at that point it was nothing more than a bunch of parts directly soldered together… looking more like a jungle gym than a guitar effect. The following day the circuit was carefully installed in an enclosure so as not to alter the sound, and with a few more tweaks became the template for the HEAT BLASTER.

My imagined sound was sort of “orange,” so the HEAT BLASTER enclosure is orange as well.
