I have a 6545 and a vintage JCM800(Slash). I was freaked out when I A/B'd them. They sound SOOOO similar. The clean is completely different, but the gain channel is almost identical...Anyone else had a similar experience? I love the JCM800, but I don't want to deal with problems that could happen with it, durring a live show, so I use the 6545 as a duplicate.......So, the battle...... Both are very loud. CLEAN channel..800wins... GAIN channel..Draw... SIZE..6545 wins.... DURABILITY...6545...wins So, the 6545 wins.....Fatality...HA!!

The 6545 in my opinion is much better than any JCM 800. Even better than that is the SRZ-65. The SRZ has a bit more gain and is a bit thicker sounding to my ears. Either way I'd rather have a Z than a Marshall.

If it was that the cleans were different ... then try cleans on the 65 side with the master all the way up and compare that to the Marshall for the same sort of front end rather than the 45 side front end.

Any way to change out the tone on the 45 side? More of that vox/ac30 sound? If switch out some preamp tube, or something, can I get it to come closer to breaking up and make it a little less ping pong sounding?

Not really on the AC-30 tones .... the AC-30 has a much different feel and response as it is cathode biased vs the different back end and UL output transformer of the 6545 on the 45 side. If you want pure dead on AC-30/4 tones listen to the Mantaray ex. Stingray. You also really need a 2x12 open back Vox Blue cab to nail those real AC-30 tones and a 6545 would blow these in short order.

Actually ... depending on the tubes and bias of your JCM 800, with a set of #7-8 E34LS biased at 38mA you might find the cleans of the 6545 will win. I might bias even higher depending on plate voltage. ... maybe a lot higher. I would also want a good strong phase inverter. Your lack of cleans is probably the phase inverter distorting long before the output tubes.

the JCM800 cleans beat a 6545? Is this a single channel Marshall? I would find that unusual. (even if it was a dual channel Marshall)

That is exactly what I was hearing. I really liked the cleans on the 800 because the texture that the small amout of gain created. No matter how loud I get on the 45 side, it remains crystal clear. I used the 65 side and found it almost identical (BUT WAY BETTER) than the 800. OVERALL: 6545 Wins!

My burst buckers break the 45 up pretty quick. The break up the 65 up even faster.

What you described is a big complaint I have with some two channel amps... where one is the 'clean' channel....however, it is completely clean and sterile. I mean crystal clean. Hardly usable. Only in the last stages of volume increases (9 & 10) does it start to have any sense of breakup (and only with HB pickups). And a lot of the time, there is no master volume. Not a problem on lower wattage amps, but when you start hitting the 50 to 100 watters, look out.
I have a 20 year old Carvin X-amp....copy of a Boogie Mark II. Nice clone amp, but it's a 100 watt amp and with no master on the 'clean' channel, I don't use that side. (I know the X-amps have a wattage cutting switch 100/50/25, but they sound best at 100) (anyone looking for a cheap "boogie-ish" amp, check out an old Carvin X-amp...fantastic!!)
I would prefer a two channel amp where they are similarly voiced, but the 'dirty' channel takes over where the clean channel left off. (most often, they are not voiced anywhere near each other.) And separate master volumes. Like switching between two SRZ-65's. One set a little clean, the other set a little dirty. It's been my experience in gigging that you can't just switch from super clean/bright Fender to Wall of Modified Marshalls with effects. It's just too much of a jump.
When I'm rich and famous, I'll have the Dr. make one for me.

When I'm rich and famous, I'll have the Dr. make one for me. Well the KT-45 side starts getting hair with the volume at about noon with Fralin Blues Specials in my Strat. So I can set the 45 side volume right there where it's starting to grow hair and control its master volume from the airbrake, then use the master volume on the SRZ-65 side to get it to the same level as the KT-45 side. I haven't gigged it yet, but doing my first playing with the amp it looks like it will work real nice like that. YMMV obviously. Everyone likes something different - and a lot of folks don't want to use attenuators. I use them all the time, and for what it's worth, I get a lot of complements on my tones.

Let us know your thoughts when you gig with it.

Benttop Let us know your thoughts when you gig with it. Will do. The next time I'm out where I plan to use it is the 15th, so I have some test time available yet. Still trying to get fifteen pedals on a twelve pedal board here... DRAT! I also want to check the bias and make sure things are running right in that regard - the power tubes on this thing seem to be putting off a LOT more heat than the same power tubes in my Flexi-50, but I'm running its bias a lot colder than what is recommended for the 6545 which may be the reason for the heat. I am playing out tomorrow, but it's a short one hour gig and I don't want to hump two amps out and then discover none of the songs use one of the amps. I can do that whole gig with the Flexi, so I'll wait a week on the 6545 and get it tuned up in the mean time...
