I would recommend a TS808 for that bluesy overdrive with that whoopy, howly mid, I don't know about the US, but in europe they are rare and expensive collector's items, luckily they are reissued by the original manifacturer who made them for Ibanez in the '70's, Maxon, the price is fair and the sound is truely authentic, never heard an overdrive like that, except that other special overdrive pedal: Maestro's parametric filter/overdrive designed by Moog, it's got a tone wheel to adjust the frequency, around 750 hz it's crazy! cheerio, guy
