Yes. I was speaking of line in, that's where you need a preamp, on mic in your 
pickup signal might be a bit to hot already, but in any case the impedance of the 
guitar pickup is too high (sorry i wrongly said "converted to high", meant "to low" 
above, see http://en.wikipedia.org/wiki/DI_unit for a good explanation).

not really; any active DI-Box will do, e.g.Behringer has cheap ones. Personally I 
use either my Roland GR-33 guitar synth (has built-in speaker simulation too), a 
cheap and small marshall valve-state guitar amp or an ancient Roland analog synth 
with pitch to voltage converter(P/V synth SPV 355, great stuff :)), or the (also 
ancient) Ibanez DM1000 12bit 19" delay processor for my electric guitars, and a 
Fishbone Preamp for the piezo pickup in one of my classical guitars.
