The HotBox 130 is our top-of-the-range power-attenuator and enables you to drive your valve amp brutally hard into those sweet overload conditions yet output just the perfect volume. Simply connect the 130 between your amplifier’s output and the speaker itself then turn your amp up to overload levels and the excess volume is absorbed leaving you with the true sound of your amp overloading but at a manageable volume.
This is our first ever attenuator with stepped rotaries: The ones that most manufacturers use are weak and flimsy inside, which limits power flow and creates failure risk so until now we have refused to sell you short by using naff parts just to cash in. But! We have finally found a source of very high-powered (and expensive) rotaries. So now you can have your cake and eat it: Power and elegance!
Our HB130 is 100% point-to-point wired and made by hand in Manchester, UK using only the highest quality, premium parts. We use a custom wound oversize inductor, mil-spec power resistors, custom made heatsink and high current switches for maximum quality in every aspect of our units.
Tuneable inductive attenuation
Choose between four settings: Bright and tight Resistive, the big and open Blue setting, the midrange focussed Green setting or the Warm and full Cream setting.

I’m surprised this item isn’t more well known! Awesome product, very transparent and doesn’t colour the sound. Excellent customer service. Sean has been very good explaining any questions I’ve had and has got back to me with speed. Really looking forward to future products. Really love that there are four settings to add a bit more warmth in steps. Super robust and well built. Thanks Sean!

These are great attenuators. Much better than a master volume. Now I can pump my vintage amps into a bit of power amp overdrive without destroying my hearing. I do have to turn up the treble a lot to get brightness back but much better than resistive only attenuator. Well built too. I have a 4 Ohm unit and now I’m buying an 8 Ohm too.

Wow, I’ve been waiting years for this kind of product, and it doesn’t disappoint! I’ve always wanted a simple to use attenuator I can carry in my gig bag, sit on my amp and which can vary attenuation depending on venue…as well as providing the rock sound I get from my Marshall 1987…previously at excruciating volume! This meets my needs in abundance! At the moment my preference is the blue reactive option to cut through in a hard rock setting but I can see times I might switch to others…it’s great to have the options. I’m also very reassured by its reliability and interaction with the amp, as I had previously been a little concerned about the potential impact on my Marshall head unless I spent over a £1,000 on a device I wouldn’t want to take to gigs…that is until now! I get the strong impression Audiostorm are passionate about making high quality products and give the necessary care and attention to each one. Customer service was 100% too with great swift communication as well as a speedy despatch/receipt.
Well done all, you’ve made me happy!
