My subjective preferences for those effects are:
-Tuner : Sonic Research Turbo Tuner. Really fast as its name implies.
-EQ : Empress ParaEq. I prefer parametric EQ pedals, they solve more problems.
-Compressor : Cali76 Compact Bass. MXR's compressor is cool, but lacks clean blend and HPF, which makes it less useful overall.
-Octaver : MXR M288 Bass Octaver Deluxe. We have a common winner here. The ability to mix subby + middy octave sounds makes it very versatile.
-Fuzz : Aguilar Fuzzistor. I tried MXR M84 for a while, but I subjectively felt like it gets lost in the mix easily.
-Chorus : Walrus Audio Julia. Clean blend is very useful on a chorus.
-Phaser : Aguilar Grape Phaser. MXR phasers are notorious for volume jumps and tone suck. Besides; I feel like the Grape Phaser sounds sweeter; possibly because it is targeting bass related frequencies or something.
-Reverb : N/A. I use MXR Carbon Copy Mini in bright mode instead. Bass is already a "bassy" instrument, it is very easy to sound muddy with reverbs and whatnot. In my subjective opinion, a bright delay setup to mimic a reverb is the best option. Plus, MXR CC is analog.
-Loop : N/A. I used the Boss RC looper for a while, but didn't try any other alternatives to compare.
