5 more because it is a rainy Monday morning and I am procrastinating instead of getting ready for work:
Original Frantone 3 knob Peachfuzz - My guitar playing 15 year old always remarks how great this sounds. (Dad Rock tones that impress the teens!)
Subdecay Liquid Sunshine mk 2 - The perfect light grit, sparkle pedal.
Morley Volume Pedal - Over 20 years old and still going strong. (Knocks on wood.)
Catalinbread Katzenkonig - More versatile than any rat because it is a Kat.
Hotone Krush - Tiny and versatile bit crusher. Perfect for ruining your sound and not expensive.
They would be only what I have and use...
MXR - (this one is hard as I like all things MXR) Carbon Copy, Micro Chorus, Micro Flanger, Phaser 95 Mini, Reverb M300, il Diavolo Overdrive, EVH 5150 OD
Dunlop - this one is easy the Cry Baby Wah (and also the Echoplex EP103)
Way Huge - Saucy Box overdrive
Boss - GE7 EQ
Ibanez - Tube Screamer TS9 (none of the other models just the original or reissue TS9)
for extra credit-
DOD Compressor 280 and TC Electronic (any of their Mini pedals)
