| Tchad Blake used to use various Sansamp pedals on a lot of his recordings, with his "go-to" being the Sansamp Classic.
He's worked with Elvis Costello, Peter Gabriel, Pearl Jam, Tom Waits, and a ton of others. One of the very best and most ground-breaking engineer/producers out there.
For the most part, he has used the sansamp on just about everything else you could think of, including syth, vocals, saxophone (yes, that's not a misprint) and especially on kick drum. I read a quote of his where he literally said "Always on bass. Haven't recorded a bass amp in 15 years."
Typically, he will use it in the mixing stage instead of re-amping a track. Using just a little bit of fuzz from the sansamp and blending just a little of the fuzz track in with the unaffected track is one of his trademark "secrets" that's not really a secret. |
