Tone King Ironman II Mini Attenuator

I bought this to use with my Marshall SV20, since it is way too loud and doesn't have a master volume.
It's amazing to have so many options to attenuate your amp with quality without paying more than 500 euros. I feel like there is some minimal coloration on the sound, but I could be mistaken. Either way, I can get many amazing sounds on the amp while using this device.
The high cut option is noce, but I don't really like what happens to the "Marshall sound" when I use it.
I would also have liked to have more impedance options, because I don't find it worth it to pay double the price for the bigger Iron Man just to be able to use 16 Ohms.
All in all, I really love this piece of gear. I use this one for my Marshall cab and a Torpedo Captor 16 Ohm for my other cabs.

I use it with tube amp Marshall DSL20HR at home and I am sure, that this attenuator can release all power of your amp with great sound! This device will show you a huge diffrence between using a tube amp on low master volume level with high risk to disturb your neigbours and using it with normal master level and acceptable loud, especially with high gain. I was afraid, that it reduces sound quality, but since I got it, I don't see any alternate to use tube amp at home without attenuator now.
Simple in use and good quality.
For such price there is few features, but I bought it only for good sound quality at low volume and I got the desired.
Also, there is no any active cooler inside, so you will not hear any extraneous noise.
