Nice review Jo, the price is less than I was expecting.
Just to be pedantic (Moi?) any volume control be it TDK or Alps is an attenuator, in function if not description.
Personally having had experience of relay attenuators I still prefer a stepped attenuator approach. With the relay attenuators there are a lot of relay contacts in circuit, with the stepped attenuators there can be as few as one contact (the Acoustic Dimension).
I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan
