Fender Ultimate Chorus help with pedals

I've recently began playing guitar again and today my dad gave me his old Fender Ultimate Chorus amp. I was playing on a champ 25 previously and it only had a single input.

I can't figure out how to set up my pedals (mxr full bore metal and cry baby wah) correctly. I initially tried to go through the input like i did on my old amp but with this one it has the mono/stereo inputs. I did very brief research and used the mono input/output with the wah pedal first and the full bore metal second. On the clean channel the amp now has a slight distortion sound without the mxr pedal on or overdrive channel on. and the wah isn't working at all.

Never had any pedals growing up playing so i'm unfamiliar with how to set these up. Need some help. Thank you!.
