It was speculated that Dave used a boss FA-1 FET preamp, which may be true for later years, but as shown by the document he used an MXR m162 preamp, as the FA-1 had not been released yet. The document seems vague, but it's important to note that the m162 simply was sold as the "MXR preamp". I've tried this pedal with the rest of the gear listen including the 50 watt lead Marshalls and it sounds spot on. It's the secret ingredient to his tone.

According to Guitar Lobby, Dave used TC Electronic Flashback Delay.

According to Guitar Lobby, Dave used MXR M68 Uni-Vibe.
