I had a Le bass and replaced it with the Revolt. Both are great would say they are different rather than one is better than the other.
I do miss the hot/cold fusion in the Le Bass, I used to get a great hot tube amp grind in hot fusion which I can’t get from the Revolt.
channel A on the Revolt is revoiced (Ampeg style) and is better than the Le Bass channel A, but it is very clean
Channel B (Marshall super bass) is really good as well. Channel c is great fun and super heavy aggressive but not really used by me except for a bit of fun.
it’s a shame you cannot blend A with C as the channel C blend is just dry bass ( which is fine) and I wish they had kept the Fusion option as I do miss that.
Overall Revolt is slightly better sounding on all 3 channels, but the Le Bass was more flexible for a more bespoke sound.
You won’t go Wrong with the Revolt, it’s straight out of the box everything at 12 sounds are all great and it won’t disappoint, but if you really miss the Le Bass features like Fusion you may want to look for one second hand.
