Like the majority of people who buy this, I wanted a way to record my amp silently. I didn't want to pay over 200 euros for a "reactive" load which isn't really reactive (to get reactive you have to pay a lot more than 200, the closest popular "reactive" competing product is actually not properly reactive but uses it more as a marketing tool). It turns out this HB attenuator does a fantastic job at providing a clear line out signal. Running a Laney Ironheart at 60 watts at high volume, the attenuator doesn't seem to heat up at all. It's completely silent. Also, the actual attenuation (which for most people is just a side bonus feature) is great! Now I can have my master volume cranked up, my channel volumes cranked up, and the overall speaker output down at 0.5/10. I was afraid this might change the tone too much, i.e. remove a lot of high end, but no, it is minimal - it sounds a LOT better than just having the master volume turned down. The amp now sings. A great purchase.
