Jettenuator is great! I have it in on all the time
Playing through valve amps and living in an apartment,I end up either playing through my headphones or at really low volumes. My main usage is therefore, as a load box so I don't have to use a speaker/cabinet.

Main points:

- Versatility: This unit will work with any amp in the world rated 100w or less. Most units attenuate a specific ohmage. This unit has inputs for, 4, 8 and 16 ohms.
Though being rated at 100w, I even use it to attenuate a 120w head. I do not crank it to the point where the power stage would be outputing more than 100w however, goes to show you the effort in building this unit.
You can use this as an attenuator or a full on load box. Another possibility is to attenuate the signal of you amp and via de line level, send through effects processors or power amps.

- Reliability: Soldano really put this unit through its paces. The components are of the best quality possible and build quality and finish are impecable. Never had an issue with this unit in 2 or 3 years.

-Sound: Like all attenuators, the sound will darken a bit. This is to be expected and is not in any way excessive. You will probably have to compensate dialing in more Highs and HighMids and taking some low end in your amp. I use it to my advantage as I am a single coil player so it helps taming those piercing highs perceived by some bright amps.

If looking for an attenuator, do not pass this one! Give it a go, it's the most versatile unit on tha market with an exceptional price! Of course, if your plan is to use this with a cranked 120 or 150w head, this won't do.

Excellent & dangerous attenuator
This attenuator is small & easy to use.
It is very versatile because you can use any combination of speaker cabinet
with any amp that outputs 4, 8 or 16 ohms. A BIG plus

Sound-wise, thus unit is very transparent and the stepless attenuation allows fine-tuning. Even on the nearly maximum attenuation setting , the sound is good.
Top end remains, in comparison to some other brands.

I did not yet test the micsim feature, but it might be handy in some situations.

The big danger with this unit is that you can severely hurt yourselves :
don't touch the unit when using it or after using it.

It becomes EXTREMELY hot and is impossible to touch / move after usage without some form of protection. When you quickly need to break-up your gear after a gig, you might be in for a hot surprise...

I am really surprised this unit has passes EU satefy regulations & testing procedures.

I strongly advice to put 2 oven gloves in your guitar case !!
Clearly this is something they need to fix in a new model ...

Used with :

Marshall JMP 100W Plexi
Vox AC-30
