I think by "cheapest way" he means the absolute cheapest route.. I'd say if you're using just one amp, (tube amp) anything set cleanish with a fulldrive 2 in front will do the trick and get you very close. And just a basic (cheap) delay and reverb pedal, in that order, will fill in the sound for your effects. Assuming you already have a decent amp, these 3 pedals could be had for under 300 bucks with the FD2 being about half if you were to buy one new.
If you're going for a real low volume set up, the fulldrive 2 has a bit more gain than a ts808 so it will work better. 808 doesn't put out quite as much gain. Personally, I like the 808 (have a couple of them) but for low low volume, using it for your dirty tone, you'll need to stack it with some other OD..
