Tonal differences between 90- and 45-watt setting

[Scooter]

Has anyone noticed a big tonal difference between the two power settings on the ED?

A few weeks ago I was in GC trying out a LS Classic for the umpteenth time, trying unsuccessfully to tweak Ch2 into doing something I really liked, when I spotted an ED in the corner, which I mistakenly thought was some kind of down-market Stiletto. I wasn't very interested, since I'm not really a Marshall kinda guy, but I tried it anyway. Like many of you, I immedeately bonded with all three of its settings, and now I want one of these things.

I was struck, though, by how much more shimmery and complex the clean and LO sounds, especially, were in the 90-watt setting. Even with the master just below 9 o'clock, I thought that switching power settings had a pretty significant tonal impact that I couldn't EQ my way around. The 45-watt setting wasn't bad, but seemed a little mushy, and mid-rangey and one-dimensional by comparison.

I don't really need such a powerful amp, but I'm getting addicted to that 90-watt Simulclass harmonic haze. Anyone else experience this or am I just fooling myself?

nope it isnt just you. 90 watt setting is pure magic. thats the simulclass speaking. ive got a question along the same topic...is 45 watt mode class A, or class AB, not that it matters, but i would like to know. Mesa's website and manuals are contradicting

I find at low volumes the 90 watt to be darker. But when I am letting it rip I prefer 90 watt as well.

But I think a lot of that is the fact that it comes with a 90 watt speaker. My experience has been the higher the wattage the speaker, the more you need to push it to get the best sound out of it.

Pretty sure 45 watts is pure class A....

I much prefer the tone in 90Watt mode.

The main difference I notice is that the low end is reduced a bit in the 45-watt settings and most importantly, the master volume knob is easier to dial in a not real quite/not real loud setting.

Other than that, I've never really noticed enough of a difference to love one power mode and hate the other.

I agree, not enough of a difference for me to worry about which one I use.
