HotBox 120 Resistive


The HB120 is our dual-mode resistive power attenuator offering high power handling and easy to use features. Fixed Studio mode is ideal for precisely repeatable results such as recording across multiple sessions, and variable Jam mode allows you to smoothly fine tune your volume right down to zero. Two speaker outputs mean no need to daisy-chaining multiple cabs and our design tolerates mismatched speaker loads without harming your amplifier. I find that rock players and Marshall owners in particular tend to like this unit for it’s robustness and big, open, bright clear rock sound.

HotBox 120 Resistive

Simply connect the HB 120 between your amplifier’s output and the speaker itself to get the real and unique sound of your amp overloading, but at a manageable volume. Our units are built to last using only premium and British made parts, so you can drive them as hard as you like, for as long as you like, without any worry.

Dual Mode

We’ve taken the guesswork out of attenuation with our easy to use, two-mode switchable system. In Studio mode the HB120 provides the perfect volume for studio recording or garage-jams. In Jam mode the HB120 reduces your amp to levels ideal for solo practice and bedroom jamming.


  • Suitable for any valve amplifier up to 120 watts.
  • Dual mode with fixed (Studio) and variable (Jam) settings.
  • Works as a Dummy Load (Set volume to zero in Jam mode).
  • Available in 4, 8 and 16 ohm versions.
  • True bypass to let your full volume through for A/B comparisons in the studio.
  • Designed and built in Manchester, UK using premium components.

    Great attenuator!! Built like an absolute tank, yet very delicate on my tone. It sees some amount of abuse and does not seem to mind.

    Really like this .a great edge of break up sound at manageable volumes .Doesn’t colour the tone either .I connected it wrong originally and fried the volume pot and Sean very kindly replaced it .I’d like to claim credit that due to my mistakes he’s now added a red colour where the amp input is !

    Best attenuator I’ve even owned. I’ve had a few, including Weber Mass Lite and the very popular Jettenuator and Bugera PS1. With the HotBox 120 tone sucking is gone. Tried with Orange, Marshall and Fender amps. Incredibly easy to dial exactly the amount of attenuation I want while the other attenuators give me a volume that is either too low or too loud and suck tone. And when you set the HotBox to 0 no sound comes out. I can’t say the same for any of the others I mentioned.
    Ordered and got it the following day. Top notch company and product.
