I am a rythm player wanting some pedals. I play classic rock (60's-80's).

The FX I use are mostly are OD, compressor/sustainer (to add sustain to chords, and to even out spikes), chorus (for thickening), reverb (for natural ambience).

what are some other pedals that I could leave on 100% of the time? or is that ^ it?
Equalizer. Seems strange to have chorus on all the time, but thats just me.
I don't give a shit if you listen to me or not
Is that your only question, what effects to leave on all the time.

you probably couldn't use this all the time but i think it'd be good for you to get a wah pedal.

You mentioned that you're a rhythm player so I know of a pedal that'll delight you but I don't know what's your budget is.

It's Adrenalinn III and sells for $375-$400.
Shouldn't the Super Champ XD have some basic effects on there?
