Peterson Bassmaster P150 - Rare Item Purchased used 3 years ago. I bought it because I was drawn to its very good, sticky sound and warm tone. This model uses a 12-inch Electro-Voice speaker and features a carefully crafted hardwood cabinet. As it is a very old item, I would appreciate it if someone who understands this would purchase it. There are no operational problems, but please be aware that there is some crackling when turning the knobs. Because it is a rare item, you probably won't be able to find one in this condition. If you have any questions, please feel free to ask. Please note that shipping will be on weekends due to work commitments. It will be shipped in a dedicated hard case (with casters). Thank you for your understanding.
