Changing the pt80 op amp?

[nico21]

I am building the PT80 (GGG kit) and i was wondering if upgrading the tl072 for a ''better" opamp (like opa2134) would have any interest, or if this idea is a waste of time (and money!!)

Thx guys!

It sounds quite nice with the normal TL072.
The delay repeats are not entirely clean because of the nature of the cheap digital delay and adding a better opamp would therefore not be very noticeable i guess...
Nevertheless a great pedal...
