Recommend me a music store(s) in Portland, OR

Greetings,
As the title states, I'm looking for recommendation(s) for music stores in the Portland area. I'll be visiting in April for a week. So I figured, why not stop at a few stores and play around with some basses that aren't often seen over here in Michigan(at least not be me anyway).

Particular basses I'm looking to try are; Spector, Aria, Modulus(or G. Gould), and Dingwall. Who knows? Maybe I'll find one I like and ask if they ship. That would be one heck of a souvenir.

Any help is greatly appreciated. Thank you.
