i've got a vht special 6 head. i've been using it as a pedalboard amp. it does take pedals very well. you just have to spend time dialing it in. i think "eyes" was talking about the special 12/20. don't let the low wattage rating put you off. i've used the special 6 for small club gigs without a problem.
lately i've been running my old rocktron pro gap pre amp into it. i can get some decent tones with this rig and with the built in hush it's quiet enough to record with.

btw.. i think i'd really like to have a special 12/20 r/t.. so yeah.. i'd buy another one. i've had my 6 for about two years and it's been flawless. speaker efficiency makes a big difference with the 6. i've run it through both a homebrew 1x12 with a vin 30 closed back or an early '50's jensen bluebell in an oversized homebrew open back. sometimes i'll use them both.
