A braced solid Rosewood Back for the 000
Had some more time today to play, during our “Stay at Home” mandate in Ontario. Oh well, I’m using my time to do some projects I had put off. Playing with the CNC will be next.
I have a 1962 Silvertone 1472, 10watt Tube amp. It sounds great clean. It also sounds great cranked, when it starts breaking up, but way too loud with anyone else in the house.
So I decided to search for a Master Vol mod.
It has 2-Instrument input jacks, & 1-Mic jack on the rear. A Volume & Tone ADJ pot for Instrument, & Mic on the front of the amp. This adjusts the gain to the 2 - 12AX7 pre-amp tubes.
The amp is all original, 12” Alnico Jensen speaker, but replaced the Tremelo caps 2 years ago, & the 3-prong AC power cord upgrade for safety.
After research, I found a simple 1Meg pot mod. Might not be the ideal Master Volume, but it’s simple, so I thought I would give it a go.
I decided on the single pot Master Volume “Type-3”, adds a 1MEG pot to pin-5 of each output tube, from Trainwreck Pages.
I first tried it with jumper wires with alligator clips to see how it worked.
Seemed to be good, so I soldered wires in.
Since there are 2 - Instrument jacks & 1 -Mic jack on the rear, I decided to remove 1 - Instrument jack from the hole in the chassis to mount the Master Volume pot.
I took the mounting screw out, pulled the jack back inside the chassis. The wiring is all solid stiff wires, so I just left it attached & it can’t go anywhere.
No holes where drilled to accomplish this mod.
I added a ground wire to the jack I pulled back inside, in case it acted like an antenna picking up noise, since it got it’s ground from the chassis.
The wires from Master Vol Pot - Tubes, I used braided coax, so the wires where shielded, keeping interference to a minimum. Braid grounded to the pot, open at the tube ends, with heat-shrink. It looks like the braid is exposed, but has a clear Poly coating, so the braid isn’t touching any wires.
The Instrument & Mic jacks are in series in that order, before the input to the first 12AX7 pre-amp tube. There was a resistor that linked INST-MIC, reducing the INST signal, so I added a jumper wire from the tip of the Instrument jack to tip of Mic jack. Now it doesn’t matter which I plug into, the level is the same.
So now I am able to use the front Volume controls as Gain, & the rear control as the Master. Allowing me to drive the pre-amp 12AX7 tubes with Gain, & turn down the Master that adjusts the 6V6GT power tubes to a comfortable level.
If I want to use it as the original Volumes where designed, to get cleans, I just Max the Master Vol, & adjust the original front Volumes.
If I ever want to take it back to stock, I remove 3 wires & the Master Pot from the chassis, put the jack back in its original hole in the chassis.
Sounds great, has some crunch when I want to add some.
I have a death trap on my workbench. I took a small gamble (£27) on a 1950s portable Pye radio and I could have done better. I wasn't hoping for a working radio by any means, I was expecting a mess to be honest.
I think I'm going to have to just gut it and see if anything that comes out is salvageable, fingers are still crossed I'll get my money's worth out of the Mullard valves B7G base valves, speaker, output transformer and the case is pretty cool. The Power transformer does not look healthy but I'm yet to pull it out of its cage. I doubt I'll make a radio out of it, that would be a considerable effort to restore it and frankly local radio is crap.
I'll either make a cool little half watt guitar amp or just an amp to play my phone through
New pickups showed up in the mail today. I asked Matt from Rainville Audio in Owen Sound, Ontario to custom wind me a set of humbucker pickups to match the Bare Knuckles Crawlers I have in my DIY Cherrycaster.
Out with the old Gibson 57 Classics, in with the new Rainville’s.
Installing them in my PRS Tremonti SE Custom.
Matt nailed the sound!!
I have an A/B foot switch, with the 2 guitars plugged into the same amp. The AX84 P1ex I just finished.
Just slight difference on the high strings, but I think that’s due to the difference in the colours of the guitars.
Making holes, making holes...making a P-Bass...
It’s coming along. The trem isn’t installed, it’s just there for the photo. That’s the next step.
The Sprite 4 string CBG is getting some work done.
1. Got a little fret sprout going on so I'll be filing those back.
2. Going to add some aluminum shielding tape to the inside.
3. I'm removing the ceramic mag PBass pickups the measure out to 4k each for the SD SPB-3 Quarter Pound PBass Alnico pickups that are 5.5k. Hoping these make a big difference. The others worked, but I think they'll be a better fit for a Bass/Whamola I'm going to build later.
4. Changing out the old gate hinge tremolo I made for an old Tiesco/Harmony style tremolo. May have to add some wood to the tail piece to make a better platform for the tremolo. May use that gate hinge trem on the Bass/Whamola project.
It IS nice occasionally to work on something you didn't have to build
Everybody that knows me knows the love/hate thing I have with all things Gibson. So you shouldn't be surprised I watch this guy lol. Well not long ago he did this video
I actually paid attention without ranting . It's also no mystery I build VERY few Teles and NEVER a thinline. Now I've WANTED to like a thinline but every one I've played the first thing I did hard rap on the back. I'm NOT trying to start the wood vs pickups debate. BUT with my chosen style of pickups it DOES make a difference. My single coil choices are 6.5 max and very lightly potted and slightly microphonic. Not enough to speak into (Teisco) but enough to carry resonance. And every Fender thinline I ever tapped was a dead thonk! Not a bad tone but NO tone. Which told me the pickups are too hot and the thinline thing just for looks. Not that I think everyone should be like me but I'm like me.
Now when he started his cheap guitar review he accidentally bumped it and there was a note (doesn't matter what note just that there is one). I sat up and listened closely, the good bad and indifferent. Apparently he has criticized these and they sent this wanting an honest opinion. On a lark I happened to have enough money (2 cents shy of $125,free shipping) so I ordered one from his affiliate link.
This is what I got
Well I got an email with a support email AND phone number and a little shipping damage. They offered me a new one but I already had it apart putting Tru-Oil on the neck and it wasn't much
Matching crush on the bottom of the box. A block and tap with a maple mallet, ready for epoxy
I thought the neck shim hilarious
A little dry epoxy and Truoil later, almost ready to reassemble
And of course I need to help with supper
I've seen the Glarry semi hollow jazz boxes on Amazon and had to talk myself out of buying one. A. I don't even want a guitar that big, and B. I wouldn't play it if I bought it. Too inexpensive though....
Very much so, and the Strats (far from my favorite guitar) are crazy cheap and pretty damn good. What I find even more interesting is the support from the in country supplier. Every issue Trog spoke of they addressed. Better tuners (approximately the same as MGB) and the string ferrules. Mine are good and snug, not tight not loose. And guitar pick or not the action was spot on and the neck straight. The factory strings looked good but were 9s and I prefer and have a load of 10s.
The body is basswood with an approximately 4mm top. Only hollow on the left side but with more resonance than an Acoustisonic as is lol.
Yeh Marty, I like your taste in the old ones and too bad they don't make one. A Vox Phantom clone would be beyond cool
Well there are these...
Eastwood VG6 2000's Red/Orange Burst Rare and Discontinued Vox Phantom Copy | Aaron's Gear Depot | Reverb
True but cheap? Uh ah no
Ok. Sigh. More complications. Looking at that picture I noticed the half moon plate is out of alignment. Now the new Wilkinson bridge/trem I’m installing is a different shape. Also in comparing the string spread of the old bridge to the new one it may be that the new bridge is a bit wider. I’ll find out if it’s a problem when I string it up.
I’m sure I’ll have to relocate the half moon plate.
Made a jig to clamp body blanks. I only have 2 long clamps, even if I had more, this jig makes clamping blanks much easier to glue and clamp. Made the 2 pieces of clamping timber long enough to handle tele, strat, and bass size blanks with holes for the 2 rods for longer or shorter blanks. Holes are drilled to clamp blanks in the center of its thickness.
Been very pleased with how it works. I still use 2 alternating long clamps for added support in the middle (not sure whether it actually makes any difference)
Last night I was searching, trying to find a DIY faceplate idea for the AX84 P1ex I just built.
I came across free program I downloaded called Front Panel Designer.
The company’s idea is you design what you want with a selected material, then you save the file, send it to them, & they build you the faceplate. The software, it has a “Price Calculation” button. Then you could see if you want to spend the “big bucks” and get them to do it. I’m already at $60, & not quite done.
In the program, you can also print the file out at 100%.
Looking at different ideas on the internet, how people have made faceplates.
Print it off, laminate the paper, then mount the paper to the face behind some clear plexiglass.
Transfer the black lettering onto the plexiglass, then paint over the back.
Print on some coloured Vinyl then mount under the plexiglass.
Not sure yet which method I will try.
I’m able to position the holes in the software, then print out at 100% to see if they line up perfectly with pots & switches on the amp.
I think it’ll turn out pretty nice, whichever way I decide to go.
As illogical as most amps are laid out (to me) this should be a walk in the park
But I wasn’t logical when I built mine & drilled the holes.
No longer on the bench, the Dipole mandolin is finished!
Hmmmm, doesn't look like my old 40 meter dipole
QSL on that.
