So I have two small 5 watt tube amps and Fender and a Crate. They are not at all similar in tone, the Fender is smooth and creamy and the Crate is bright and twangy. Using the left and right outputs in my Amplifi FX100 floor board I have a left and right amp, I'm running the board naked save a touch of reverb. Running them together this way they really seem to compliment each other with a full rich room filling sound that is better than either amp played solo. Does anyone else run two dissimilar amps at the same time or am I just a whack job with too much time on my hands?
