Re: JTM45's might be the perfect single channel amps...
I am usually a 2 12" kind of guy but the tone i was getting from this bassman today at gc had very prominent bass and mids which I wasnt expecting. I think Jensen makes better tens than 12s from my exprience

yeah both are great amps, i'm just sayin if you switched the cabs on them both would sound much much more like the other

Fuchs-20 for cleans & SUPERB OD without pedals...open back 4x10 w/Celestion G10-Ls/Jensen P10-Rs in an X pattern.
Edana-45 for semi-clean & cruchy; LOVES pedals...open-back 2x12 12H30/12M25.
Marshall 1987X for leads....newly destroyed by UPS, so the jury is out at the moment on what it'll do & thru what cab. I'm thinking closed back 2x12 w/maybe V30/"Greenback" mix???

Re: JTM45's might be the perfect single channel amps...
I played a 65 block logo JTM45 through a 70's 4x12 loaded with black back 25's once. I compare every amp to that one now. It's my refrence tone in my head from now on. It had original GEC KT66 tubes. With a strat it was very nice chimey cleans- with the guitar volume rolled back just a touch. With a strat volume dimed, it could get a kinda flutey EJ type overdrive, and the amp volume up high. With a bucker it could get pretty thick. It did remind me of early EVH- cranked up with a bucker. Great stuff! Plenty loud, but not overbearing.
Yeah, a real good one can probably only be improved on with high quality reverb. I understand the more recent Marshall re-issues have an effects loop. I don't know how that works....

Re: JTM45's might be the perfect single channel amps...
some of the posts that I have read indicate that the typical guy who is looking to buy a JTM RI is not exactly thrilled with the newer effects loop models. With any of the JTM 45's you have to pretty selective about what speakers you use in a 4x12. You won't be able to drive your typical 75w speaker cones with any kind of authority, ergo, no cone breakup. This is an amp that was just made for a 2x12 closed back cab, but i would guess than any of the 15-30 watt Celestions or clones would do the trick in a 4x12. When I get mine, I'm palnning the stick with the Celestion Heritage 30 RI's that I have in my 18w. JTM's do not seem to have quite the power of the later 1987x 50w plexi. Not sure if it is tranny or the rectifier, since the two tranny JTM45/100 puts out 100 watts. The specs i have seen say that the 45 actually puts out more like somewhere in the 30's. Anybody know for sure?

Re: JTM45's might be the perfect single channel amps...
Doyle once wrote that the early 45's put out about 35 watts at clipping and a little more (45?) flat out. The reissues are said to put out almost 30 at clipping, but more with improved tubes, particularly a improved rectifier tube.
It's not just JTM45's that may not sound as good trying to push high wattage speakers. I think most all 50 watt amps and less, sound thinner pushing multiples of 60 -75 watt + speakers. Those low wattage speakers are part of the mojo. Nothing breaks up sweeter than low wattage alnicos IMO.
When Marshall issued the hand wired, offset control panel, white face re-issues a few years ago, the matching 4x12 cab had the two top speakers open backed, and the two bottom speakers enclosed. They said that the original 4x12 was that way. The speakers were Celestion 15 watt alnicos. I understand that the Alman Bro's used to 1/2 back their 4x12 speaker cabs too. Additionally, they have been reported as using JBL alnicos.

Re: JTM45's might be the perfect single channel amps...
I was once told that Duane used two fifties daisy chained, but they were the bass models, not the lead model plexis. Richard was reported using a single 100 watt plexi head. I do know that Richard reported using mostly the 100 watt models, and playing with the bias settings, in several interviews.
Too bad you didn't get to try the 45 with KT's, because in my opinion they are much more ballsy than regular 6L6 types.

Re: JTM45's might be the perfect single channel amps...
Stratman and I spent several hours today running his new Edana 45 through that Bluesbreaker-sized 2x12 ext. cab. It has the low wattage Mojo versions of the G12H30 in it. Sounded pretty sweet. I've also got a 25m (Greenback mojo copy) that I'm going to stick in there as well to try the mismatched thing.
Sucker got pretty loud. When he recovers from his 27 hour flight, I'll let him chime in on his.

For those of you who have owned a reissue JTM45:
I've been told by more than one guy that you can't put KT-66 in a reissue JTM-45 because the cabs are too small...is that true?

That's true of most of the Blues Breaker combo reissues, but not the heads.

Re: JTM45's might be the perfect single channel amps...
The early ones were too narrow for KTs....the older ones fit but were right on the valance or damn close.
I had a '98 & it was pretty close. The valance got very warm after a short while

Re: JTM45's might be the perfect single channel amps...
OK - After I left Scott's, I headed to Houston and visited Danny-D's a store that has several better than good guitar slingers to compare the head through different cabinets and a whole lot of guitars.
Business basically stopped with at first 9 people and finally 12 people standing around the "JB-007" (As I am renaming it) head.
We played three different EJ stratocasters, four Les Pauls, my modified Jaguar and a Fender Jaguar, an SG with P-90's and a PRS. Both positions of the sweet and bitch switch were used as well as several pedals (aka Tube Screamer and the sort.)
Owner, salemen, and customers loved to full bodied tone and character of the head through Genz-4X12 cabinet (Running at 8 ohms) and 2X12 open back cabinet (Running at 16 ohms) with the final vote being cast between three items, as follows:
1) EJ Strat running Sweet through a 2X12 open cabinet at 16 ohms.
2) My Warmoth body/ USA Custom neck stratocaster that uses SD-JB, Little 59 & Phat Cat with EMG modified tone and boost through the 4X12 cabinet at 8 ohms
3) 59 Les Paul running bitch through a Marshall 1960 cabinet with original celestions.
Looks like Scott might have to give up his realtors gig and start making more of these heads (PS Scott I told them about the Franklin)
I will be posting clips later, if Scott can agree with my poor playing capabilities.
