Re: Need some opinions on these amps
Well, of the ones you've mentioned I've played the Diezel, the SLO and I'm currently playing a Splawn Quickrod, which is similar to the Jcm 800, just a bit hotter.
I'd say for current metal the Diezel, but I didn't really care for it for lead work. It felt a little compressed, dark, and weird feeling to me, kinda like I was disconnected from the amp. But that's a personal thing.
For one that can do a lot of things really well, especially lead work...I'd take the SLO in a heartbeat. Creamy overdrive, really good articulation...doesn't go mushy at all. It'll do 80's metal...forward. I love it. It's got a pretty good clean as well. And to my ears anyway, sounds pretty damn good at lower volumes.
As a matter of fact, although I really like the quickrod, I've recently played the Soldano Avenger, which is just the overdrive channel of the SLO...and I'll be picking one up soon. It kills.
The Jcm 800, great crunchy tones. That's one that really excells when you push it hard. It's Marshall goodness. Wouldn't be my first choice, but it's a legendary amp....
So I'd go SLO...
