Free The Tone Custom Series FB-2 Final Booster Boost Pedal


This product is not currently available.


    Product Description

    The FB-2 is a versatile boost pedal that can be used in a few ways to improve or just boost your guitar signal. It has up to 20db of clean boost, which you can use to get your guitar louder for your next guitar solo, or to push the valves of your tube amp harder, for that lovely tube saturation sound!

    The FB-2 doesn't reverse the phase of your signal as a lot of boosters do, which can result in a perceived signal loss or 'tonesucking'. So it has a clean internal circuit that will push the signal of your guitar.

    3 ways to use it

    • Directly in front of your amp to push the tubes and get a saturated valve sound.
    • Before your overdrive pedal to push the drive from the pedal more and result in more distortion and volume
    • After your overdrive pedal to keep the same tone of the drive pedal but increase the overall volume.


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

    The FREE THE TONE FB-2 FINAL BOOSTER is a full-range booster that can provide +20 dB of boost. It will not degrade the highs and lows of your guitar signal when the effect is turned on and will provide a natural sounding boost without affecting the original tonal characteristics of your guitar or bass. The HTS circuit is also built-in to preserve the sound quality whether the effect is turned on or off. The Final Booster does not reverse phase when the boost is turned on. Although it is not widely known, boosters that employ a single-transistor or FET circuit cause a phase reversal when switched on, and this can cause the sound to drop in level or result in phase cancellation. The Final Booster does not have this problem.

    • By implementing the HTS (Holistic Tonal Solution) Circuit that manages signals comprehensively from input to output, the effected sound and bypassed sound will always have the same sound quality, which solves a problem that has plagued players for years.
    • A full-range type booster that can boost up to +20 dB.
    • Natural tonal characteristics provided by a circuit composed of transistors, without using IC chips.
    • The FINAL BOOSTER does not have a phase reversal problem that can cause the sound to drop in level.
    • Exceptional sound stability by using long-life high reliability components
    • HTS (Holistic Tonal Solution) Circuit


    The Final Booster uses discrete transistor circuitry with no ICs and it has a natural high-end harmonics sound. The sound of the old model was highly appreciated, however I was asked by a user if it was possible to reduce the switching noise level. A true bypass circuit was used to switch the effect on/off so it was difficult to reduce the switching noise.
    In the summer of 2012, I developed the HTS circuit when I designed the GIGS BOSON and IRON FOREST pedals.

    I thought the HTS circuit may solve the problem with switching noise, and it worked well for the booster too.

    The switching noise level was reduced thanks to the HTS circuits and it preserves the sound quality whether the boost is turned on or off.
    If there is sufficient headroom in the amp being used, the FINAL BOOSTER can be connected directly to the amplifier's input and used for straight volume boost. If you’re using a tube amp it can be used for drive boost. The reason for the “FINAL BOOSTER” naming should now be clear… it will normally be the last pedal connected in an effect chain. Of course you could also connect it before an overdrive pedal in order to clip the overdrive input stage and create new distortion effects, for example.

    A booster is essentially nothing more than a volume-increasing device, but in actual use it goes much deeper than that. Different sonic nuances can be achieved by connecting it in different ways. Using it in combination with overdrive or distortion pedals can produce some really interesting new effects. With a little ingenuity and trial-and-error testing it can be a source of unexpected new sounds.
