SPL Reducer - Passive Power Soak For Guitar & Bass Amplifiers
Arriving Soon Notify me

Less Volume, All the Tone

The SPL Reducer does what its name implies, reducing the power output of your guitar or bass amp - while maintaining the killer tone you so meticulously crafted. This means you can overdrive all kinds of amps, particularly tube amps, without disturbing the neighbors or bludgeoning your bandmates and overwhelming the monitors onstage. As with the other SPL power soakers Transducer and Cabulator, the company developed the Reducer in coordination with the amp specialists at Tonehunter in Cologne, Germany. If you dig your tone but you're too darned loud, take it from Sweetwater - give the SPL Reducer a try.

How Reducer works

Place the SPL Reducer between your amp head and speaker cab. Reducer converts the amp's electric power into heat - which it dissipates. Reducer is passive, reducing your volume with resistors, so it requires no additional power supply. Passive power reduction guarantees you accurate sound reproduction without affecting the frequency response curve, so your tone is preserved perfectly - just at a lower volume. For the amp output, Reducer gives you impedance settings of 4, 8, or 16 Ohms. For the first stages, reduction is stepped, but it can then be adjusted continuously thereafter.

Little box of black magic

This little box performs exactly as stated. Drastically reduces your volume without any compression or hindrance, on top of using no additional power supply with a really small footprint, so you can dial in that sweet spot.

Awesome

Best attenuator I've ever used!

Amazing!

This is absolutely amazing. No detectable difference in tone, even when at very quiet settings. I can let my power tubes roar while keeping a very quiet sound level. Using it with my Mesa Boogie JP2C, I get brutal tone at family-friendly volume.

Works as designed

I bought this to tame my Mesa Boogie Mark IV that I use in my basement. It does exactly what it says it does. For my amp, it allowed me to turn the volume up higher than I normally do to really get that sweet tube-amp tone without deafening my ears. My family has thanked me for it! heh

Fantastic unit

I wish I had pull the trigger on something like this year's ago. It would have saved me from buying so many amps. Or maybe not but... still. On the other hand I am happy I waited for the best one to come out to the market. With the SPL reducer I can now let me 40-watt combo sing without blasting people. Before all I had was a clean amp, now I can chose what to get out of it. The unit itself delivers pristine audio while keeping all the warmth coming out of my amp. I can't perceive any tonal loss and it is just solidly built. Road ready for sure. BE AWARE! The middle knob has a scratchy feel to it. I thought I had received a defective unit but my sales engineer Ryan send me a second unit to compare only to realize this is by design. It seems that the idea is to feel the increments but it doesn't get to be a click and instead feels more like a scratchy pot, but in no way it interferes with the sound. Just a heads up if you are touchy with your purchase and feel like returning it as a defective unit. Ask for Ryan! The best rep. one could ask for!
