Thanks!

I don't think the trannies matter as much as the ears of the builder.

that said, are you registered over at the D*A*M forum? they live for questions such as these.

What Dev said. OC75's sound good in that circuit.

But I have also built 1.5's with AC125, 128, 151, and various other transistor combos that sounded good.

AC128 is my preference.

NKT274/OC42 combo!

seriously though, its all about the gains not the numbers on the transistor case.

OC75...
But measure their HFEs...

hehe yeah fair enough, OC75s seem to be the reliable choice for most circuits it seems, though get this - i have NEVER used them in any pedal! ;)
used just about every other OC series transistor but not the 75!
i had a creepy mk1 a while ago with all oc75s in, sounded great, but no greater than other mk1s i have done myself with alternative transistors in there.

i have an absolute humdinger new pedal coming up very soon!

i got one of your mind rockers (i think kosta was the originall owner) and i'm very impressed of it. got a great sond idea with that too. so i think i need to get some others. buzzaround, doom bender and harbinger are tempting. but sounds of today also... hmmm :)*

so what is the new pedal? :animal:

I love it too, but Ian wants to go closer to the original looks and thus it will be red on silver with a red baseplate. I am having a hard time not to pull the trigger on this. It is damn sexy, but there are so many things I want atm. :cry: 1st world etc.
