I have read about this before but it has been several years...I think this is documentation that is out of synch...I think there is a difference in the presets between version 1.00 and 1.10 of the firmware...The FBV is nothing but a controller...The name of the patch and everything about it is all stored in the amp...accessed by the FBV...I had one of those sorts of cards that came with my amp and I remember that it did not match exactly...My amp came with 1.10 on it and I think the documentation has always been 1.00 for the Flextone 3...That is if my memory is correct...

Not sure what to tell you about a Satch tone...But here is what guitar geek says he was using in 2000...

A flextone 3 is a great amp but it's missing some things. To really nail his tone with the Flex you might need some key missing peices like the DS-1...Maybe an extra Delay in the FX loop to do spillover...

Looking at this I would probably try the Plexi 100 or JCM800 amp model...Greenback 412 cab model...SM57 off axis....Setup a Chorus on the MOD in post...I think I would go with the Analog Delay model post for the DD-2 (DD-2 sounds a lot like the DM-3 analog delay and the Analog Delay in the Flex is a Memory Man model)...The Plexi is pretty light in the gain department just like the real one so you could drive it with the compressor...You would get a better result driving it with a DS-1...You will get more gain from the JCM800 model....

stomps in front of this amp behave a lot like the do in front of the real thing and this amp has only the compressor gain stomp so there are some missing bits. I have always used some extra stomps with this amp...It has 90% of what I need built in...
