Yea, it's quite tough to pick something out that's NOT a tube screamer derivative.
However my favourite flavoured picks would be the Barber LTD. Based on the TS, but with a really good eq and presence control. Really lovely, low gain drive and set up right, sounds much thicker, without being bassy. I have the modboard version, which lets you fiddle with some clipping options, mids, input bass, noise reduction etc.. The way I have it set up, sounds really wonderful with single coils. Keeps the detail in the highs while slightly softening the attack and bumping up the low mids.
Also a major, major fan of the Lovepedal Kalamazoo. Also a TS derivative, but with an interesting treble boost and brightness controls. I've been tempted to get my hands on one, but a local pedal builder is making me something similar. Sounds great with both single coils and buckers, but this would be my choice for an ultimate humbucker pedal.
