Frankenamp
My Haze 40 morphing into a JMP 50 plexi. It started a while back with this 1.6mm carbon steel flat pattern, I folded it - wish it were as easy as writing that. Marked & measured, agonized over fractions of millimetres at times the rest of it. The top adapter plate is 2mm aluminium, sprayed in VHT wrinkle paint. Back panels recycled packing case plywood. Drew up my own 'plexi' faceplates and had them cut/etched by local engravers. They really do line up magnificent with the chassis, just sitting approx til the controls go on.
Anyway looking forward to what happens next on the Amp Shop bench.

Funny you should say that, I've dubbed it 'Black Op'. I could only discuss where it owes it's origins to verbally over a beer. You'd be surprisedash wrote:Using your work skills for good instead of evil!!

Re: Frankenamp
Looking at the bottom three pics, the "agonized over fractions of millimetres" is readily apparent. That is superb craftsmanship. Keep the progress pics coming!

Re: Frankenamp
A last chance ride out of town on xmas eve and arrived the following day. Knew I should'a photoed it there in then sitting outside on the concrete in the sun. Went straight into action, short acquaintance with sound dial in and gigged two nights. Way too loud for the little venue (brought the 5E3 for the news years eve session). Will shoot some tonight.

Re: Frankenamp
True to my word here's some pics from the shadows of the cave. Ryan's brief was to do a circa 1968(year) circuit for 1987 JMP, no added things like master volume etc... Just turn the loud tap on like my Twin. I wanted a fender jewel pilot but it had to have classic marshall knobs, chickens just wouldn't be right. The cab and hollow chassis left home weighing in at 16kg, came back 8kg or so heavier with a circuit & iron.
It sounds good!! quintessential marshall, I found the lead channel a bit brittle & piercing and switched to the normal channel with it's rich ever so dark tone, pushing up the treble & dropping bass control. I boosted with catlinbread SFT pedal set pretty much to treble boost, gain off, treble max, bass min. I've got something else planned for this.
Loud with volume on 2 out of 10. The original 'marquee' 66watt speaker from the haze doing a great job. I remember first playing that haze & thinking the speaker had a plastic oily quality of sound then after a couple hundred hours it bloomed into this dry crispy distinctly marshall thing.
Ryan's done some good stuff here, I know little of, just leaving him to it with an empty chassis based on 1968 era and a chunk of kickstart funding. At idle the thing makes the right amount of white noise, very quiet for such a raw beast.

Re: Frankenamp
Get that volume knob up past 7 and this channel won't be brittle and piercing at all. It will be rich and godlike!!!calling card wrote: I found the lead channel a bit brittle & piercing and switched to the normal channel with it's rich ever so dark tone
It'll also be LOUD.....(and hopefully not too much for your 66 watt speaker.....)

Re: Frankenamp
Ah yes get to critical mass!, Must mess around with a patch lead between channels too.
LOL I indeed hit about 7 on the initial fire up and got some very concerned looks by my hosts, explore I shall...

Re: Frankenamp
I second this Crank it up and let the lows and mids catch up with the highs (which have the unfair advantage of passing through the bright cap) ... or patch the inputs and dial in just a wee bit of the normal channel to warm things up.NZRS_Matt wrote:

That speaker is really good - I was expecting it to be a "cheapest you've got" ala Rocket 50, but it's actually really sweet, and was handling the amp's output nicely.
