I don't know if this has been done before, but I thought that it would be nice to have a list of the guys that are building all tube bass amps. I guess the first question would be 'what constitutes boutique?' For the purpase of this list, I'm looking for the little known builders. Obvioulsy, there is Orange and Mesa etc. but everyone knows them.
