The 3TM is from what ive heard "plug'n'play".. its basically a board with 3 tubes and a cable connector that you just change with the 2tube board thats already in there.
The other mods require soldering and some basic understanding of electronics.
I would definitely get that one!
If you like having a fuckton of bite in the sound, ADA is the way to go.. and the 3TM makes it sound more modern without getting rid of that bite!
hey dude u have any idea where i can get it moded??? I been trying to search but when i go to the ADA website it directs me to some guy who mods them in the UK.
