Try a Digitech RP 255 , it' s pretty versatile , and you can put a lot of effects on one setting and change sounds by going up and down the settings , pretty simple once you get used to it . Boss also has somthing similar , but is probably a bit dearer . Might even be able to pick up a multi- effects pedal on e- bay , Both Boss and Digitech come with an expression pedal that functions as either a wah-wah or volume pedal depending on how you want to set it . A word of warning , go straight into the front of the amp and not into the effects loop . If you have a setting with overdrive or distortion going into thr effects loop you get noises and harmonics that would scare the crap out of a werewolf . Another plus is most multi-effects are mains powered , so no batteries going flat . you will be entering a realm that you may not come back from . Good luck on your journey
