Whut up.
I cant give you any advice on the Paia Tube Pre, but I know I have looked at it in the past, and would be interested to hear what others have to say about it.
I have purchased from them before, I bought a Mod Box kit, supposedly a distortion pedal...actually I bought 2...the first one got jacked.
I cant say this was the greatest purchase I have ever made. I found it insanely difficult to get working, and once it was working it was really iffy...on one minute off the next, although it did sound all right. Finally I come downstairs one day and the damn thing wont turn on....it just went. I took it to school for some electronics open house and it got swiped, so I couldnt try and fix it. So I bought another one to try and see if I could make it better, and this one was a real bitch...it just wouldnt work.
Thats just my experience with Paia.
