Walter Wood’s makes his really legendary handmade amps in different versions with one, two or four channels. When they first came out in the early 1970’s, they were the first amps designed for the double bass. For many bassists, the Walter Woods’ amp is still the reference amp. They are available as special order directly from Walter Woods only.
