Up for sale is my Music Man HD 150 bass head. Just back from my tech with the following updates: New SED Winged 6L6 tubes, new main filter caps, and retensioned tube sockets and retainers. The Winged SED 6L6's really beef up the tone, nice and chunky and warm sounding. Some of the numbers on the dials are faded out, along with the front badge, typical wear and tear conditions for a 30 year old amp, but, otherwise, she's good to go. Gotta be a local sale, as I really don't want to take the risk of shipping this head, which weighs about 45 lbs. However, if you want to pay for a UPS Store packing and shipping on your dime, I'll get an estimate and add that to the cost, AT YOUR OWN risk ! Don't want to be responsible for damage in shipping ! If you live in the Cleveland, Detroit, Ann Arbor, Toledo area, I would be willing to drive halfway for delivery. $550. Not really interested in any trades, but you can always try.
