My bassbuddy is looking for a small all tube or hybrid amp with a headphone input for late night practice in his vacation house. It has to be able to be used with and without a small basscabinet. He and I haven't found any yet, so...any one got any suggestions? Any help will be appreciated, including the creative out of the box ideas, as long as it is (more or less) serious. Our thanks in advance for your effort and troubles!
