Hi guys ,
The amp and its owner are up in Newcastle.
Differences between the F1 and the LM II
The LM II sounds as if it has more of a mid scooped tone, whereas the F1 is flatter.
The F1 has a digital power amp section which results in a supper fast and accurate response
The F1 is half the size !
I'm sure theres loads of people on here that can give you a more technical answer but there both good amps , however the F1 is probably the better of the two .
