Yes, very good. I went to the forum and used the search function to great success. There were quite a few people who hold this pre-amp in high regard. If it's modded anyway. :rolleyes: So I ordered from ada depot a software upgrade. Right now it'll really only give me more presets, but in the long run I will need it for any other mods I do. I think I'll wait for them to put together some more of the 3MT (upgrade to 3 tubes not 4 :eek: ) do it yourself packages. They also had some affordable tubes so I may consider getting some of those as well. Thanks for all the help guys. :D
