the BOSS TU-2 tuner seems to be close to the standard. it's a great unit and from what i understand you can also buy a power relay pack that will allow it to function as a power source for other boss pedals in your chain.

as for compressors i know boss has a specific bass compressor unit. never tried it though. the bass specific pedals probably offer a wider EQ range for lower frequencies but guitar pedals will work just the same.

like any other effect pedal purchase your best option is to try out as many units as possible and go with whatever sounds best to you.
