I like it! Good work, and nice bass tone. I see he uses a fender but on the recording it sounds gibby-ish to me. A good thing!
The bass on the whole album is an OLP Music Man copy taken from the direct out of his Nemesis 200 watt 4x10 combo. Funny thing about that; all the instrument tracks with the exception of two guitar leads, one additional harp track and one harp re-take were all recorded live in their practice space and the only problem with leakage I had was a distorted induced vocal on the bass track, which was the result of a speaker cable laid across the bass line-out cable. You can only hear it if you solo the bass and crank it, but I think it's funny.
In a prior incarnation of the band, Brad used an Epi Thunderbird, which was the tonal benchmark I shot for. He's not really a gear head and will pretty much use anything remotely playable. While there is a continuity to all the tracks, musically, each track is also somewhat divergent stylistically. That track is pretty psychobilly, but the rest of the album is a little different, with each track having its own personality.
edit forgot to add: shaker and tambourine tracks were also later overdubs.
