Sorry I'm late to this conversation...I've been visiting my Mom, and she lives in the land of dial-up, so no internerd for me for a week...and see what I miss?

I'm a regularly gigging musician, tube amp player (bass and guitar) and could see my way to spending that kind of cash on an amp...but I'd want a stripped down version of these specs. The specs for 03-through-12 seem good to me though.

I don't use overdrive, and haven't for 20 years of playing, so I'd only need one channel. I want to keep my sound warm and full and clean...so 300w is right.

I've got to be honest, with space and transport concerns, not having a rackmount version would be a deal killer for me, especially since I always use a rack tuner into the loop on stage. I'd take extra depth and maybe a 4 space face to keep it in a road amp with a tuner and all wired up to plug-and-play. I also ask for reasonably even weight distribution for loading...which would help to protect against load-in/out mishaps. I would think a rack mount version would also help keep weight down.

I'd also wish for 2 fans...one for each end of the amp to make for even airflow across the tubes. In a hot club or outdoor show when a tube amp may be powered on for 5 hours or more hot tubes just destroy good clean tube tone.

I'd like the switch for the Pre/Post DI to be on the front, but the DI on the rear...so I don't have to fumble around in the half-dark in the back of the amp when I've got my bass on and space is tight and I'm in a rush, etc.

Having easy access to the tubes for 'in case of' situations is a consideration, as is having the tubes work in pairs...so if one goes it drops wattage without losing your amp altogether.


I'll be interested to see how this comes out...there are more than a few people here who have no problem on spending 2-6K on a bass, not to mention amps, cabs and such. I see no reason that this wouldn't be a viable situation.

The only other features I could ask for are for it to be rackmountable and to have a blend control to blend the 2 channels (or maybe send ch 1 out through ch 2), but these features are certianly not a deal killer once I get the $$ :smug:

I'm still working on the blend idea. The more I think about it (and the more you remind me about it ;) ) the cooler I think it is. For now, I'm going to have to release the amplifier as a head, but I'll soon work on a rack mount version.

Personally, I would use it as a head at the moment, but the reason I would like to be able to rackmount it is in case I want to get a nice rack later on. My ideal setup for it would be as a head which could fit into a rack, but that may not be possible, even if you make it very deep and pretty thin...

Well that does it. Now I'm looking at my gear wondering what to sell first. Switchable FX loop and a rack mount version in the future = start saving up the $$.

Even though you are from Texas there is only one name for this beast:

Mjolnir

I believe it is pronounced "miller" and is translated to "that which crushes". It is the name of Thor's hammer. What could be better than the hammer that makes thunder!!!

az

P. S. - I would go for one of these heads as well.

Ha! I was going to suggest that one (see my avatar), but given Brads other names, I thought that "The Ox" was perhaps a bit more line with the others (and it ties in the British connection, versus the Viking allegory).

Great name, IMHO!

I did notice your hammer. For years I have thought Mjolnir was a great name for either a bass or an amp.

I have an inlay of that hammer on the neck pocket overlay cover on my 4-string Skjold (which is nearing completion!). I wanted to use some Norse symbols (to reflect on Pete Skjold's Viking ancestry; and on my interest in Norse mythology), so I have Mjolnir on the overlay, and Gungnir (the symbol for Odins spear) for position markers. :D

Anecdote:

Mjollnir, the hammer of Þór- (Tor, Thor) was made by the dwarf Sindre, and when Thor threw the hammer, it always hit what he aimed for. Then the hammer returned by itself. Thor could will the hammer into any size he wanted and he wore a pair of iron gloves to hold the hammer with.

Cool stuff huh?
