Id'ing transistors from within a set

Hi,

I have a tonebender "set" of ac125s (or ac128s - can't remember which)  that I have mixed up such that I now no longer know which is Q1, Q2 or Q3.

Is there a way I can ID them using a basic multimeter with no Hfe/leakage capability?

THanks

Hopefully this meets your "simple" requirement, but you can (and should) build this:

Very easy build and it works great.

There is an RG Keen article that explains it that should be easy enough to find via Google.  [EDIT: it's linked on the page given above]  RG Keen...is there anything the man can't do?
