New Mosrite Custom Shop

[Johnny]

Sounds really cool, and I never knew mosrite made amps too, but I think for now I'll stick with the marshall stack of JMP (or JMP MK II, that one is cool too!) and a 4x12 cab or two. Or 4. What kind of price?

Are they going to the same as the originals or will you delve into valve territory??

... I read that post but that was posted by mosritetexas ... not MosriteCustomShop and figured they were 2 separate copies being produced.

Hi All,
First, thanx for having me! I'm stoked about working with the Mosrite folks and all you Mosrite fans! I'll try to answer some of your questions.

It was Greg Lewis (aka: mosritetexas) who came to me with his idea of reproducing a new Mosrite tube amp. Greg and I know each other from the guitar show circuit, where he's seen my hand-built tube amps for several years and liked my work. We've been working closely on the look, features, and sound of the new Mosrite amp. He told me what he wanted, as a fan and expert on all things Mosrite, and I did my best to deliver that.

Why tubes?
Mainly because we (me and Greg) dig the sound of tube amps. Also, it's much simpler to build a one-off, hand-built amp with tube circuits and eyelet boards and point-to-point wiring.

Why solid state rectifier instead of a tube rec?
A couple reasons. 1) Greg wanted the amp to have a really fast attack, like the later/bigger blackface amps or a marshall. 2) simpler 3) more reliable and 4) Dumbles all have SS rectifier.

I haven't seen an original Dumble Mosrite, but I have built several ODS clones and poked around a real Dumble Overdrive Special from the 80's. There's also many D-type schems floating around the 'net. I used much of this for ideas/inspiration.

What circuit was I replicating?
I didn't really have a circuit to replicate. I didn't have any schems for the "original"/Dumble Mosrites. For this project I figured the features (volume, bass, treble, 'verb, trem speed and depth) and the sound we were after (big and clean with killer 'verb) would dictate the circuit. What might Dumble have done in the 60's? I started with a fender-style preamp w/D-type part values/voicing and a fender brownface-type trem. I figured we'd want a long-tail-type phase inverter/splitter for a tight sound and lots of drive. I wanted to try a different type of reverb circuit that returns to the splitter w/no negative feedback. That turned out to be a great idea. Lots of juicy reverb tone, fairly simple to wire, and doesn't suck tone/load the circuit. The amp tuned out with this big, open sound that was better than we'd hoped. Organic, sustainy and alive. Very much an extention of the guitar. I haven't tried it with pedals (like overdrive/distortion) yet, but it's not a hyper-clean amp like a TwinReverb, so it should be very pedal-friendly. This is truly a NEW Mosrite tube amp.

Price and availability?
Don't know. We're still talking about pricing. Look for it to be in the $1400-$2000 range. A lot depends on how the LA Guitar Show goes, feedback from players, etc. I am working on a #002 prototype for Greg. Past that, we don't know. I'm hoping after the show we can post some more info including gut shots and soundbites/video. After that we may accept orders for handbuilt units. If future units have as much handwork as the prototypes (did I mention I hand-drilled the chassis in my shop?) they will be very expensive. If we can get batches of chassis and cabinets made to our specs cost/assembly time will go down quite a bit and we might supply dealers. We should know more next week.
Thanx!
