I linked them both to my 1926 2x12" cab, one per speaker, and used the Morley A/B switcher Mickie threw in with the pedals euan and I bought from him a while back to switch between the heads and see how they differ in crunch tone.. I was also looking to see if I could dial the exact sound from my 6100 into my JVM...

Isn't that a thing of beauty?




One thing I noticed is that A->B->A between them is fine, but when you have both amps running at the same time into both speakers in the 2x12" it sounds like they're out of phase and cancelling each other out, it sounds exactly like an out of phase setting on a Mustang or my Baja Telecaster S1 switching options. I think I'd need to modify the A/B box internal to flip the phase to run both heads at the same time through the same cab - I think they'd sound fine through two different cabs, I dunno - worth another experiment sometime. Anyways it's not something I think I'll do as the whole point in me having channel switching amps is to use them for clean and crunch and whatnot innit.

Here is a video of teh clean channels and the out of phase sound when both amps are together - you can also hear how seamless and fast this little Morley switcher is. No ground hum either. Impressive.


DAMN NO EMBEDDING

So I mucked around and ended up dialing in the JVM's OD1 Green to sound exactly like the 6100 Crunch channel, which was awesome. My initial preconceptions from being away from the 6100 for a while was that the Crunch Orange was most like it but I actually dialed in a lot more gain and some upper mid cut into the 6100 which is more present in the OD1 Channel, I'm using the Crunch channel for more of a medium gain chunk in comparison.

Here is a video of my initial comparison of the crunch sounds before I tweaked OD1 - apologies it's just a camera phone video but I was downstairs, it's not clipped the mic though, and you get the general idea. The difference in sounds is exaggerated by the 6100 speaker being nearer the phone and so having more treble to it.



DAMN YOU NO EMBEDDING

Anyyyways. Then I whacked the JVM on my 4x12", I actually have never used it with the cab as the 2x12" is what we rehearse with and use for smaller gigs, I'm gonna use teh 4x12" on the gig on Saturday at the Theatre though which will be fun, so I checked it out and GOD DAMN it sounds nice. I had forgotten the full chunky bass that is just intrinsic to a 4x12". Next weekend is gonna be FUN. Gareth is going to use my 2x12" with his Tiny Terror.

Also added a shortscale.org sticker to this cab



Basically I was also reminded how much I love the first two channels on the 6100 - it's a really great fucking amp. I would be fine playing with it if the JVM hadn't ever come out. I think this day cemented that I'll never sell it



Then I took these pictures because I'm a nerdy twat



I had a Fun afternoon rocking

nice...

(whatever I wrote on the temp board)

ROLF.

Interesting vids Mike
JVM sounds fuller and bassier on the recording I think.
The stack with 2 heads is a thing of beauty!

I wish I could justify dragging that setup around with me, or even better if I modded my 4x12" to be stereo capable. It's ancient and only has a mono input at the moment.

The power amps are out of phase with each other apparently, I'm gonna fix using them together by taking a speaker cable and switching the red and black wires on one end, leaving the other normal. MacGuyver and shit.

Nice.
Would be a ballache to lug that round, but at the same time just once it would be infinitely cool!
Definitely do another demo when you have sorted the phasing issue.

i was thinking about calling avatar and seeing how much to get one of their 4x12's wired that way with 1 v30 and 1 greenback for each input. That would be awesome. Even better if it was wiredin an x pattern so the sound would really mesh together. Also, then when you do want to use just the one amp, it will be quiter like a 2x12 for smaller venues as opposed to the 4x12.

How did you find the Morley? I was looking into AB switchers for Casa Bonita but heard the Morley was noisyass and poppy (a little like CB, lolz)?

I've had the morely (that was mine originally) and yeah, it is not great.

I have a whirlwind that is cleaner for sure ( I sent Mike the morley as a gift to go with some pedals he bought so he could do somea/b pedal demos.) The whirlwind is also powerable by adaptor which it sucks on the morley live when the battery dies.

Now I use a pan pedal that I set up to use as a ab. That way you can have a, b, a/b or any blennd in between. It sounds really cool with stereo effects as far as noise type stuff goes. A big stereo delay or tremolo, and then pan back between amps as well.

If you want a wiring diagram it's simple:

Check out Mono, Stereo, in same cabinet.

I think a lot of that is setup specific. It's fast and quiet when I've used it. Listen to the video - no noise, no pops.

Ordered a speaker cable with removable jacks so I'll sort this out of the coming weeks. I figure I'll drag my 2x12" upstairs and mic each speaker with a JM27 (I have two) or just use my AKG C3000B Large-diaphragm condensor back aways.

Damn, Mike, those are 2 AWESOME amps to be running together. I hope you can get everything worked out, because that'll sound killer.
