Bass Northwest is located on the North side of Pioneer Square in downtown Seattle, at the corner of 1st Ave and Yesler Way. It's fairly easy to find, and only a few minutes off I-5 depending of traffic. Although I had no problems, finding close on-street parking could be troublesome; they have no parking lot.
As mentioned in previous reviews, Bass Northwest pretty much has it all. Never before in one place have I seen so much bass gear, and it was a real treat. The people were friendly and helpful. I compared prices from all the on-line outlets, and Bass Northwest gave me the best price on my new Ampeg cabinet.
You don't have to live in the Northwest to shop at Bass Northwest - they will ship to you. In the mean time, you
can take a virtual tour of their store at their website here: BASS NORTHWEST
