What's your favourite Boost?

Kingsley Page is a superb boost. Expensive but so worth it!
I also have a MXR Timmy which is very good & useful as an EQ. 

Also I like the MXR Dyna Comp Script after overdrives.

Timmy still the tops but have just discovered the  EQD Tone Job, I will have to look into that one.

For the money I do like the full size TC Spark.

My favourites (all Fuzzdog clones, not originals):

SHO
Naga Viper
DAM Red Rooster 

I also built the FD version of the Thirpy Heavy Water (half of the Heavy Water to be precise) which sounded good butwas a bit too bright and boosted quite a lot even with boost on zero. I'd like to try the real thing to see if it does the same. 

My favourite boost is the Hudson Sidecar (clone) with gain set at zero. Loads of headroom, powerful EQ.  That and the Red Rooster are still on my gigging board.
