Speaking of wah pedals ..... Ibanez Weeping Demon WD-7 (not the jr. model). I use it on Rhodes. Also great on bass. Variable Q, variable range, level matching.
Sounds great.

Tuner.

Easy.

The GAS pedal!

The best bass pedal I ever had was a Russian big muff clone with a blend knob built by a friend of mine.

Well that and my Ernie ball volume pedal

Boss Sl-20 Slicer, Z-Vex Fat Fuzz Factory, Mathews Effects Astronaut and Cosmonaut reverb pedals, Moog MF Ring, Earthquaker Devices Bit Commander and Arpanoid, and Dr. Science Bitquest are my favorites of my favorites

*Space guitarists - this is the collection to take a look into ASAP

my main & only gain/dirt/whatever pedal is a Blackstone..something about mosfet that is purer, sorta. no other pedals in my chain - ex occasionally an Echosex. i won't even use a tuner in the chain i can hear the slight tone degrade. yeah i reach down & unplug guitar from the tuner & back direct into the Blackstone..minimalist here.

I know this isnt exactly a fair or a relevant answer, but if anyone is DIY inclined then it might be. The best pedal (fuzz) that I ever had was one I made myself, by accident so to speak. I took the basic circuit of the original Sam Ash fuzz pedal and the original filter/tone, volume and "sustain" stages from the early big muff and jammed it in between/replaced the one called for in the sam ash. Now I didnt have the exact values so I fudged it and used my own stock of 60s germanium transistors (I forget, I think it was only 2 in the circuit in the end.) BUT i got a blackface vibroverb which had an input impedance that did not like the pedal (as I would later find out), and I thought it was due to me moving cross country and something having shifted. Took it apart and ruined it. I never wrote down the final version. Oh well!

+1K H9 for guitar,
but will work on anything, including an aux.

Deja Vibe--uni-vibe clone. That Hendrix tone--outta this world.

for distortion, I'll go with the Lovepedal eternity burst, I've had about all of them and this is the one if you're looking for the tones of Montrose, Gibbons, Bad Company, Skynyrd and others

I have dug a special hole in my heart for the Red Llama recently. Especially with the rare/vintage Motorola IC.

Some of them just hit you that way...you never know.

The Diamond Memory Lane II is my favourite guitar delay, and I've had (and have ) a LOT of them. It melds with clean(ish) amps in the most naturally way I have heard, becoming less of an effect and more a part of the sound. It also has a really useful feature set for live performance.

Analog Man's King of Tone remains the most guitar and amp friendly overdrive I have ever used. I've tried hundreds of ODs, and so many of them can sound great under specific conditions, but the KOT just works well with every guitar and every amp I put it into.

I have to give AnalogMan big props in general. Anything that he has ever touched, that I have tried, has been A+++ superb. From tube screamers to fuzz face, whatever, he seems to have an ear for perfect tone. I guess I will have to try the King of Tone one of these days...

EHX Deluxe Memory Man, always and forever. Incredible with synths.

Exhuming slightly old thread... Got a Blackstone (Mosfet Overdrive 2S) about a month ago, and it's taken me that month to get my head fully around it. So many adjustments and mods possible. I haven't swapped out any components (easy to swap out socket-mounted caps), but I have adjusted the internal trim pots. Backed the TRBL some, and also the GN2 trimmer, and the pedal came into focus. It's extremely reactive to the guitar input, pickup type and player attack. I have it adjusted for single-coil, and love, love it, but would need to tweak for a Humbucker pickup guitar.

Back off guitar volume pot a very short twist, and it cleans up beautifully without losing much volume. And with these settings, it allows the character of the guitar to come through.
Beauty is the two channels, Brown and Red Drive. I used to need my Maxon 808 and a Boss OD, but the BSA takes care of it all. Set the Brown for overall "hair" and texture for chording and general lead tones, and Red for screaming sustain (i.e. Santana). Viola! Love this thing and the amazing versatility that Jon Blackstone built in. Well done!

the green and civil war russian big muffs are among my new G.O.A.T. holy grail guitar pedals. also massively involved with the Red Llama from now on.

Cesare Diaz gave me a tremadillo he designed it rocked

A buddy has one. That's a rowdy pedal . I used one of the original Big Muff pie back in the early 70's. A Les Paul into that beast to a solid-state Acoustic 150 head with two bottoms was the $#!t.

My ADA flanger and an Xotic Blender combo.
