Testimonials
After using one of James Smiths attenuators it turned out that my amp was a very low watt amp and didn’t require an attenuation
He not only refunded me my money but also came by to pick up. James is a nice guy with lots of technical knowledge.
I Will contact him in the future as these attenuators look solid and are a lot lower in price than most attenuators

Hi James.
I bought this attenuator from James with low expectations considering I have no previous experience with this type of device. All I can say is wow … if you have a full tube amp but can’t play at your condo or apt because ,if you turn it up to the breakup point where it sounds best bothers your neighbours/ Family then this is what you want. Exceeded my expectations and is very usable. I did not notice any loss of signal as most of these devices do to some extent. James was very honest and up front about his creation and it does what he says it does. Nice job James.
