I have the great fortune to be the endorser of Eich Amplification, a German amplification brand founded by Thomas Eich. I use a T-500 head paired with two XS112 cabinets and they suit every occasion. Tight but warm, loud but lightweight.
My Eich rig, pictured here with my De Gier Bebop 5.
For the right occassion, I will also bring my Fender Bassman 100 head from 1976.
