Noticeable is also that he runs a Yamaha SPX-90 in series right before his Boogie M190 amps.
The Ibanez, MXR, and Ditronic has been replaced by Lexicon and Yamaha effects, but the general design of his 1987 system is basically identical to the 1985 system.
Two Valley Arts and a Yamaha APX-10N [click here for picture] for a acoustic solo spot was used.
For this tour he added a Marshall 1959 amp for overdrive sounds and a "no-amp-loop" for his clean sounds.
High Gain sounds is still produced by a loaded Mesa/Boogie Mk.III head.
