Open 24 hours, but hard to recommend. Turk Street Studios Convenient location and cheap prices, but you'll have to deal with the general hassle of Tenderloin street life while loading your gear. Jackson Street is well managed and reasonably priced. Rooms are large and comfortable, though a bit dark. Great soundstage room.
Many pros work here regularly.
Rooms can be rented for hourly blocks, small PA's are provided, and a small on-site shop is available. 601 Jackson, Oakl. Soundwave Studios Located just off the new Cypress Structure in West Oakland, this space, started by the people from Jackson Street, has several rooms available in hourly blocks. Decent parking and reasonably convenient location make this a great bet for musicians coming from either side of the bay. The rooms are large and comfortable, P.A.s are provided, and the general environment is actually pretty open and sunny in comparison with other studios in the Bay Area.
