EBS Billy Sheehan Signature Drive, the early model. After purchase, I found it very useful for live performances and recordings, but it has been in long-term storage without use for a while. Upon checking its operation for this listing, the footswitch seems to have poor contact, and switching doesn't work properly. By carefully toggling it on and off, I was able to confirm the bypass sound and the drive sound respectively. I have confirmed this with both batteries and an adapter. Therefore, I recommend it to someone who can repair it. Other knobs and switches operate normally. Also, one washer is missing from the jack part. No claims, no returns. Price negotiations will not be accepted. - Model Name: Billy Sheehan Signature Drive - Color: Purple - Control Knobs: Drive, Tone, Level, Clean - Accessories: Box, Instruction manual, Bag - Connection Terminals: Loop connection, SEND, RETURN Thank you for viewing.
