Re: Mesa Nomad 45?
I would think the Nomad would have the most gain, but the F-Series amps RIP!
Guitar Player did a test of the Nomads, and the 45 was their fave. They actually thought the amp had TOO much gain. The Nomad didn't score as highly for that reason, but I think it was a bit unfair.
If you are looking a specific amp, I'd say go for it if you like the overall tone. You can get more info about the amp by downloading the Owner's Manual from Mesa's website. As with any amp, good tubes are a MUST.
If you are looking at other options in the Mesa line, you should also look at the Class A Maverick. The Maverick has less gain than many Mesas, but plenty for blues and classic rock. I have one--at certain settings if has a very "plexi"-type tone. I also have a DC-3, and the DC-3 (a two channel forerunner of the Nomad 45) or the DC-5 (2x6L6) are great club amps. These have the Mark IV CLEAN channel and a Rectifier LEAD Channel.
My fave Nomad is the Nomad 100 112 combo, with a 112 extension. Don't have one, but I have used them. I like the headroom and the Graphic EQ, but the 100 watt versions just seem to eat tubes, from what I hear. Lotta power and gain for a small cabinet.
And, while a lot of folks like their Carvin Nomads, that amp just isn't in the same ballpark as the Mesa--it's a totally different animal. If you liked a Peavey Classic 30 or Classic 50 and wanted something a little different, sure.
If you do get the Nomad 45, be sure to read the manual, as there are just so many switching options and tonal versatiliy. And I would strongly recommend that you try to find a matching Mesa 112 EVM Theile cab to go under the Nomad. I brings the knobs up to a readable level--and that small Theile cab will add a tremendous amount of punch and thump to your tone.
Good luck!
