Eric has used predominately Marshall and Fender Amps over the years.

From Mariani on, he has used vintage 100 Watt Marshall Heads with 4X12 Cabinets along with Fender Twin Reverb Amps. During the 70's, he also used a Hiwatt 100-watt head and a Mark One Boogie Head.

During the Electromagnets period he was using a one amp setup. After the recording of Tones, he went to a three amp setup with Twins for a clean rhythm sound, the Dumble for a dirty rhythm sound and Marshalls for solos.

He used a Dumble Head in the late 80's and early 90's. He dropped the Dumble in the early 90's after a power supply died, going to a two amp setup.

The pedals he uses are very interesting, click here to go to the pedals page with pictures.
