I bought it long time ago from https://www1.elfa.se/elfa/index.jsp (https://www1.elfa.se/elfa/index.jsp),for the another project(High End preamp),but did not want more.
OK.Now found good application.This PSU have excellent signal/noise ratio - but not cheap!

Congratulations maaalune.

I particulary like the shape and material of the box (what was its "1st life" ? where did you find it ? what are the dimensions ? was it originally drilled ? )

I wonder if you have put that 12VDC PSU in the stompbox or is it external (wall-wart style) ?

I did not tried yet a lo-voltage tube ovd, but only hi-voltage designs - thinking that it doesn't sound as well as hi-voltage tube ovd, relying on some friends trials heard - but I am probably wrong and will dig it personnally.

Does your release tends to sound bluesy-smooth-subtle "vintage amp-like" overdrive, with a nice regular decay and overdrive fading with the note, or is it more "heavy distortion" orientated ?

A+!
