This very cool DI / EQ served the store owner well for years with his Anderson Crowdster + enabling foot control over Piezo and Magnetic Routing and Switching. It includes a transformer isolated output to eliminate hum between two sources.
Would work with Parker Fly, PRS Hollowbody Piezo, ESP LTD EC-1000+, etc. Anything that has a piezo and magnetic pickups.
If you have any questions, just ask.
