ok, so i also use a Dave Hall Tube pre-amp pedal
http://www.davehallamps.co.uk/page37.html
which, before i went all tube big amp, was used with an assortment of solid state amps including ampeg PF-500, SWR working Pro 700W and a 1500W power amp. All sounded great, really great in fact, BUT..it is simply a statement of fact that once you have experienced in a gigging situation ( even the Dog and Parrot in Slough) an all tube head through a 410 cab, you will simply never get the creaminess and weight of Tone that all tube heads deliver. God knows I would love a lightweight soloution, the head weighs 90lbs on its own, but I really believe there is no other way.
