fender or good clean sim to pair with a dr boogie

[nonoxxx]

Hello,
Yesterday I tried a friend's dr boogie clone, and was impressed by the unit, so now I plan to make a rack version of the Markov dr boogie and I wonder wich clean sim can work fine to make a clean channel for the rack.

I find tagboard for Wampler Tweed '57 , but do you have another suggestions?

Thanks
