The best guitar attenuator I have found on the market at the moment!

David5140, 04.06.2014
This is a passive attenuator which does not alter the guitar's tone unlike active attenuators do.
It is very simple and easy to use and the minimal features may also preserve the guitar's tone, just like a simple guitar amp when compared to a more complex amp.
Also, it can attenuate up to 200W of power (for 8 ohm cabinets) which is one of the most powerful I've come across on the market.
I was considering getting an other type of attenuator which uses a speaker motor and is said to be even more transparent on tone but SPL's professional site and informative video demos on YouTube convinced me to make the choice to get this attenuator instead.
I also want to mention that SPL have a very helpful service and will answer all your questions.
Personally, I will order a second copy of this model because I have two cabinets. I could use one attenuator for both but two would handle the power more easily and the amplifier's master volume could be set higher, allowing for more power tube tone and even saturation, if desired.
As for features, it's all on the item info page; for example, variable resistance for use with different amps and the text at the back is printed both upright and inverted, for easy reading when it is connected and you want to read the connection info! Very good idea!

SPL Reducer

11.01.2016
I bought it because of SPL great promotional videos on youtube and information in their website. I was looking for attenuator which affects sound least and fits my budget as well.

What I like about it is that it does not need a power supply to work - it is completely passive and that that saves sound quality a lot I think.

I missed some functions like other attenuators have, like additional line level output or dual output to speaker ports. All those gadgets probably do reduce the quality of sound and probably needs external power supply, but I still quite missed them :D

When I started it for the first time there was lots of plastic/chemicals smell smoke coming out from it, so if there is any possibility to play it for the first few hours outside to burn all that stuff off - I highly recommend it. In my case it was way too cold outside to do anything, so the flat was really smelly for the next few days.

Later the variable switch started to not work when in position around the middle, so I sent it back/returned it. But of course it can happen to any attenuator - probably it was defected one or something.

Visually it really does look and feels heavy-duty/high quality made.

However, I still was really happy about its sound quality - if you don't need dual speaker port out or level line port out, I highly recommend it.
