Re: what to do, what to get?
I see JVM getting thrown around and I cringe. They are terribly unreliable, and horribly overpriced. If you want a british sound try an Orange, older Laney, Rivera, Cornford, Older BlackStar or mesa lone star. Hell even a 5150/6505 or 5150 III would be a solid choice. The JCM 800 was the last really great amp Marshall made, the 900s are ok but are still prone to breakdowns. I know that sounds super snobby, but I worked a store that sold marshalls, we have a total of 4 jvms. 2 50 watts and 2 100 watts. Both the 100 watts broke, one on the showroom floor and one was returned after a couple of weeks. 1 50 watt broke down on the showroom floor and the other went unsold before I left the store. They do sound good, perhaps they fixed some QC issues but I'd personally never buy one unless it was ridiculously cheap.
For 1500 find an older axe fx or even an eleven rack or pod hd pro rack and run it through something like a QSC k8 or k10. I tell myself I am going to go digital but get distracted by tube amps every time.
