I just ordered a TKD pot as I was afraid that the stepped I looked at would not have enough range of adjustment. What I mean is that another person with the same pre could only use the first step or so before the sound got too loud. The ones I looked at had 1 db steps with 23 positions so I figured 23 db of attenuation. The TKD pot has 50 db of attenuation and is continuously variable. When I have had stepped attenuators I seemed to always want a volume in between the steps. A 46 position switch would probably be fine but the ones I saw were quite expensive. I ended up getting a 2511 [ or 2508, whichever is cheaper] from HIFICOLLECTIVE for 44 pounds; looked like a good compromise between performance, convenience and price. They have some quite interesting parts and the freight to the US isn't bad.
