the Danelectro Transparent Overdrive is supposed to be a clone of the Timmy, and it's a lot easier to get a hold of. not to mention cheaper!
I was wondering about these - but I don't have too much experience of much else in this area. I've got one, don't use it much now, but it did exactly the job I wanted - dirtied up a clean amp for home use in a reasonably inoffensive way (ie didn't seem overly fizzy and let me imagine I was playing something nicer!). It can be very subtle. First I dug out my old Marshall Guvnor to do the job, but that was vile!!! So I decided to spend some "big bucks" on one of these :lol: - very happy with the outcome.
I've since ended up doing something else instead (got a valve amp that crunches nicely at low volume with no added help), but I've found that the danelectro TO would also be a perfect solo boost for me in front of a valve amp set to "blues-rock" if I ever wanted to play out.
I have to admit I have a problem with the Danelectro stuff morally. Which may sound hypocritical*, but hear me out. Paul C (designer of the Tim and Timmy) makes his bread and butter out of pedals. Dano ripped it and are selling a cheap, i suspect, Chinese made knock off. He's not the only one they've done it to, but he's one of the 'good guys'. In so much as he was not so precious of his design to let other DIYers make it, and indeed he helped them out. Dano betrayed that trust and are actively damaging his livelyhood by releasing a commercial knock off. That's bullshiteeeeee IMO.
*I might make odd clones of pedals for for me, friends and a few people here, but I'm not making a business of it. Indeed other than the Klone (which the real ones go for frankly stupid money) and Darkside (which the way we do it veers away from the original design), most of them are 'open source' designs that I've actually sold.
