Jonathan:
Congrats on your new purchase...enjoy it in good health. Always remember: Your sound quality is only as good as your weakest link in the audio chain. I learned this as a teenager and it has served me well all my life since. For added improvement, you might wanna try using premium interconnects (instrument and speaker) like Monster 1000-series or MIT. A power conditioner will also help improve sound quality and afford additional electrical protection (both effects dependent on the unit utilized). If you really wanna get silly, you can re-wire the speaker cab (and even the amp output wiring) with premium speaker wire for a small improvement in overall sound.
I personally have been looking for a dirty amp rig that I was satisifed with since my teens. I have a satisfactory clean set-up (70's silverface Twin Reverb), but nothing pleased me distortion-wise. I wanted those vintage Marshall plexi tones, but wanted the added flexibility of more modern hot-rodded high-gain tones a la Eddie van Halen. I looked at buying a vintage Marshall plexi and having it upgraded and modded, but the price to do so is retarded. Ultimately, I went with Harry Straub, but quality builders like Greg Germino, Scott Splawn, TopHat, etc. all make great hot-rodded Marshall plexi-style amps.
Harry is the Alembic of the custom guitar amp set. He'll build you anything you want. I'm getting an all-tube (incl. recto), 50W hot-rodded plexi style amp, hand-made, hard-wired all-discrete (with premium components like E-H EL-34's, Mercury Magnetics transformers, sealed MIL-spec pots, etc.) in a lacquer-finished mahogany (actually sappelle wood) dove-tailed cab. with flamed maple laser-engraved faceplate, super LED-backlit plexi laser ingraved faceplate with custom THG knobs (cocbolo with an inlayed silver tube logo), leather handle, etc. Bill Boekhoff @ Sultone is making me a matching custom-dimensioned 2X12 cab with a convertible back (closed, 1/3 or 2/3 open) with Celestion Greenbacks. It also will be lacquered Sappelle with custom grill cloth and a flamed maple face board. I'm having them both wired with speakons (as well as 1/4 phone jacks) as I feel they are superior for power signals. Custom-made ATA flight cases for both were optioned as well. Both handmade units are dirt cheap as well.
I should get my rig by late Nov., so I let you know how it sounds. Harry only builds about 10 amps a year, and mine will be the last this year (and maybe for sometime as Harry is taking a sabbatical of sorts away from amp building).
While Harry doesn't have this function on his site, ck out the Splawn Guitars and Germino Amps sites for sound bites of what an awesome modded-Marshall amp sounds like. Greg Germino is quite an acomplished blues/blues-rock player, and his amps (with a Les Paul) get the best Dwayne Allman sound I've yet heard. Harmony Central is also a good source of info.
I think Splawn can mod your JCM 2000 as well, and his prices are very reasonable. Ck it out.
See what you started: now I'm gonna need an Alembic six-string because the Strats and the Les Paul aren't gonna cut it any more, LOL!
Cheers,
Ke(vi)n
