Thought someone would like to see a pic of my Tight Arse.
It is resting on a pad of post it notes.
In on one side, out on the other.
I thought it a good idea and it suits my simplicity leanings. I’m a bit clueless in this stuff (that noise was my Father rolling in is grave) No idea if it works ! But I think it does which is what matters I guess.
As I said before it is the mk1, mk2 has an adjuster, mk3 is still taking orders before assembly of the batch (1 batch only I think was the deal for all of these) but has HPF LPF both adjustable and needs power.
