Hah! I have one of those, as well as the Caline Orange Burst (alleged BB Preamp clone). Both are actually great sounding pedals and work incredibly well together. I use the PS as light - medium OD into the OB to get extra dirt (or by themselves). Hard to beat for 40 bucks AUD.Sorry to disappoint, but my Timmy clone is a Caline Pure Sky bought from eBay.
I haven't done any internal mods, only cosmetic mods to the enclosures just to personalise them a bit:
