"The SVT 400T appeared in early 1991, I believe. It saw a lot of road and I'm pretty sure he used this for recording Nevermind. It was stock, if anything was changed it would have been the input jacks to something heavier. The SVT was used until replaced by the complex HiWatt rig."

Adam Clayton

Bassist

Verified via Tripod

According to this transcription of a February 1982 issue of U2 Magazine, "Adam uses two Ibanez Musician basses, one with an active pre-amp built in, the other standard, although he often seems to play the standard instrument throughout. This was fed direct into an Ampeg SVT400 watt 8x10 bass stack with no effects units or other gadgetry at all. This was both DI'ed and miked using a Sennheiser MD421."
