Thanks for the tip! I went there today and checked out their WAs--both the 12 and the 15. It was my first time playing the WA and I have to say I fell in love. I had a 400+ several years ago and miss it dearly, but I was shocked by how warm the WA's tone can get, especially for such a small amp that doesn't have power tubes. I went to the shop thinking I'd go for the 15, but after playing both, I believe the 12 is more my speed. It seemed punchier and like it would cut through the mix better to me.
Too bad I'm going to have to wait until my first full time job starts in July before I can pick one up.
Also, Music Gallery is a great shop. They're actually doing a small repair on my bass as we speak. Beautiful store and great selection, especially of amps.
