So I play guitar at my church, and I am currently using a Digitech 3000. I must say, it just does not live up to my standards.
My amp however is great, so I have decided to just use it.

However I still need a volume pedal, and a Wah Pedal.

So far the only pedal that I have found that works as a wah and a volume is the morley Vol/Wah.

My question to is, "Is it worth the $80?"

It's worth $80.00 but neither does it's job as well as "good" versions of stand alone wah and volume pedals. The wah is a bit sterile sounding and won't give you a good "click" in the top end. The volume function isn't really even in it's travel. Having said that, occasionally I use a Morley power volume/wah/dist. It's ok if I just wanna bring one pedal to a gig.
