I built the Kreutzer preamp in its original form, and found it was less noisy than at first expected. I reckon all the rest of your gear makes enough noise to mask any noise made by a TL072, but change it if you must... The LT1169 is a good coice. I have also built a cut n' shut version of the preamp and put it in a 100W 'Lead' guitar amp: I am quite impressed with results but would make the observation that a bit more gain would be useful providing the first amplifier isn't swamped.
