Tough, Well made Attenuator

This useful bit of kit allows you to keep that sweet saturation of the power valves, but at a much more reasonable volume for home use, the attenuator features 2 dip switches that allow you to dip back some of the treble/ bass that may have been lost between the amp and the speaker, a line out socket for recording or into a PA system and an option to bypass the attenuator. The unit is well built and I've played my valve amp throughout the evening a couple of times and the attenuator never gets hot, room temperature at most. Only downside I would say is that the unit is a bit chunky and requires a bit of room/ a surface to sit on as it won't sit on the top of all amp heads which would be the ideal place. If you are like me and live in a terraced house where you can never really turn your valve amp up due to fear of getting a cease and desist order it is well worth considering purchasing one of these.
