Darn boy! You are a natural copy writer.The Finally DI is always on with the tube preamp feeding the sweet LBA transformer, it ranges from tube clean to crunchy so it can enhance your given sound. The 1/4 output can be pass through or driven by the tube preamp. It does indeed impart a warm tube kiss to any amp.
IMHO all those pedals are better running at the end or near end of your signal chain, running them first robs you of the true benefits. Were I forced to suggest a front of chain drive it would be the Finally as it is based on the Space Heater.
The UA and all the other preamps I have tried sound great on guitar even the Slampegg Bee gets a really nice jazz guitar tone. Even the guitar oriented JC Emerald is rockin' on bass.
MORE is best when you already have a great sounding bass or signal chain you love and want to take it to the next level higher.
Nordstrand could def. use your skillz!!
I'll take one of each!
... wait a minute, I already did
