Jonny doesn’t play guitar at all on Talk Show Host. The filtered guitar sounds to which you refer are created by Ed, courtesy of his Lovetone Meatball. Like the DOD440, the Meatball is an envelope filter, but the Lovetone has a tone of its own and has many more features than the DOD. Ed’s guitar is distorted, though not heavily, which is what gives his guitar its biting character (an envelope filter on a clean guitar would be nearly as powerful a sound). Originally, he likely used his distorted Mesa Boogie Dual Rectifier Trem-O-Verb, since that was his main source of overdrive at the time.
Jonny does, however, use his EHX Small Stone in conjunction with a sampled strings sound for the track (possibly their Mellotron M400 for the recording).
