The sound is quite nice and has a wide range and like many old pedals, the quality of the sound depends to some extent on the freshness of the battery. As the battery runs down it does start to break up a bit. Having said that, the battery does last a pretty long time.
There are a few sites showing how to make your own and as, like the Fuzz Face, it's a simple circuit, it should be fairly simple - if you can find the right Germanium transistors...
One of those sites, Geofex, has diagrams and some interesting thoughts on the construction of improved versions.
On a side note, mine stopped working a while after I bought it so I took into the old Vox shop in Charing Cross Road (Macari's) and asked them to repair it. I had an old Colorsound pedal (which also didn't work) and I offered that in a straight exchange for fixing the Trem Face. When I pulled it out of my bag, the shop guy called the other guys over. They had never seen one before and as they were the ones who'd re-issued the Colorsound range, they ought to know something about them. Anyway, they agreed and I got it fixed. It has always been in the back of my mind just what that pedal was but I never saw it re-issued so it probably was just an experiment that never caught on and was dropped. The only thing I can remember about it now was that it was brown, more modern looking that the other pedals in the range and had an "IC circuit". Hmmm.
