I use the T5 and HD500X direct into the mixing board. I've found getting clean sounds comes fairly easy. I'm still not completely there with the crunch sounds, but have started getting good results by changing my way of thinking. Coming from an electric guitar background I've found the T5 to be a totally different beast. When looking for a moderate distortion I went for the amps I would normally use with my solid body electric guitar (with unsucessful results). After working with different amps I've found the Tweed model set clean seems to work the best for me. I place a tube overdrive into a tube screamer into a tube compressor before the amp. Most of the drive coming from the tube overdrive. I have the tube screamer set fairly low to add a little brilience back in. Anyway I hope it helps. But as stated above it does take time to get there.
