... all I did was upgrade my MII Tele ...


If I previously knew this, I couldn't recall; so I had to look it up.  Indonesia.

Final assembly of the Super-Tele was yesterday evening. Got the electronics installed, put the neck in, new gold plate and screws, set up the action and roughly intonated by ear. All good. Went in the house and plugged in... and... nothing. Very, very faint intermittent signal. So I started checking the obvious stuff. As soon as I loosened the screws to the control cavity it crackled to life. So I've got something shorting out either against the shielding or more likely, the battery. It was such a tight squeeze I really didn't think it was going to go. Sure enough, there looks to be a little scrubbed place on it. I made a small adjustment to the filter pot too, to make sure it wasn't contacting the side of the cavity.

I hated the idea of taking the whole guitar apart again, and I was just too tired to even think about it last night. Fresh horses today though. Opting on leaving the guitar assembled, I slipped the electronics out, masked up around the cavity and steadied my nerves. I have now routed a tray for the battery to lay a tiny bit deeper in. I think it'll provide just enough clearance. This was not fun... not one bit. How do dentists do it?!

I was able to verify the selector switch function, Filter and Q-switch with the control panel loose last night, and I do think this guitar is going to be a winner! I'm waiting to peel that protective plastic offa' the pickguard though, until the very last thing. Black shows every imperfection.

We'll slip the goodies back in this afternoon and try again. Won't be much longer now.

The first freehand pass with the Dremel didn't make enough clearance, and I haven't had time (or nerve) to revisit Super-Tele until this evening. I made up a quick-n-dirty depth gauge to keep me from boring clean through the body, and chucked the cutting bit up again. I have now routed the battery tray another 3/16" deeper than the rest of the electronics cavity, and brushed more shielding paint over the bare wood. If I don't wipe out and go to bed first, (would be a lot smarter) I'll slip the controls back in tonight.


I really hope this duzzit... no more room to rout. Next solution is a dedicated battery box in the back.

*Still got contact problems... something must be touching the shielding somehow. But my, what a pretty guitar. I'll fiddle with it some more another night.

Might I venture so bold as to suggest electrical tape between the shielding & guts?


But my, what a pretty guitar. 

It most soitenly is!

Very elegant looking guitar!  What’s the wood on the fretboard, striped Rosewood?  Pau Ferro?

Bill, tgo

Fender is using something called Indian Laurel in lieu of Rosewood for dark fingerboards on their "Player Series" guitars, and maybe the "Vintera" line as well, but I'm less sure about that one. It's pretty stuff... basically a sustainable non-CITES rosewood substitute.

Good idea on the electrical tape, Coz, if only to help me spot out what is touching. Can't possibly be the battery anymore. Might be the board on the Filter pot contacting the sidewall, I just don't see how. As soon as I loosen the screws and gently lift the control plate in the slightest degree though, she roars (and I do mean ROARS) to life. (turn the Volume down Greg...)  I just can't seem to fasten it down without shorting something out. I'll get it. I am quite happy with the aesthetics. And the guitar wears well too, with that chest/tummy cut. (I ain't got a lotta' tummy anymore... rib-cage is about all)

That is a very nice looking guitar, great job!

Maybe the short has something to do with the area near the metal plate and pick guard.

Finally got Super-Tele up and running today. I'll personally guarantee, you couldn't squeeze a gnat's nose into that control cavity now after I finished stuffing all that goodness in there. Still got at least one technical issue to solve. And some more shielding/grounding to do.

First the good part: Wow! Unmistakably Alembic. This thing definitely interprets Fender done Filter-style. And the 3-position Q-switch was a good call. Every note all over the neck, is perfectly balanced, with sting-your-ears clarity. I quickly found the extreme open filter wasn't necessary. 30-45% open was about the range my ears were asking for. The Q response was about what I expected too. The guitar plays and intonates great.

1.) The bridge pickup is dead-quiet, no noise at all. The neck pickup however, whether from a lack of shielding, or from how it's mounted on the plastic pickguard... I got noise there... hum and hiss, and I swear I heard a Spanish language radio station for a minute one time. I just don't know how to shield it any better.

Ignoring the noise issue for a minute.

2.) Each pickup when solo'd, sounds fantastic, very hot signal. But when the selector switch is set in the middle, so that both pickups are on, the signal is buffered so much that it's almost unusable. I tried tweaking the trimpot on the preamp a 1/4 turn clockwise to increase gain. (this may have been wrong) Anyway, it didn't help. Attaching a picture of this trimpot.

And for what it's worth, the noise issue present in the neck pickup is not surprisingly also there in the blended signal. I can grab my cable by the metal jack sheath, and most of the hum goes away. Doesn't that usually mean a ground problem?

So I've been playing on it, enjoying what I can... so close, but no cigar yet. I did peel the plastic off though.  ;D

The 'must-make-things-match' OCD thing took over, and I ordered some gold pickguard screws and gold pickup mount screws from Stew-Mac the other day... I'll post some finished job photos after I change out the last of the chrome bits.  ::)  In the meantime, I have been spending some time bonding with the Super-Tele. My renewed desire to improve as a guitar player is being rewarded too... in the way an Alembic does, it is showing me exactly what to do. 

I still haven't yet solved the noise issue with the neck pickup, or the disparity in volume when both pickups are engaged. I am hoping to have more free time to spend in the shop in a couple weeks, but for now, it's back to the real-gig and some very long days strung together into long weeks.

*I am wondering; that neck pickup is only mounted to the pickguard... should I have screwed it to the wood, thus directly contacting it to the shielding? Would that help?    ???

Pictures:


*and by the way, it is a radio station my neck pickup is recieving. Pretty sure it's Cuban.  I listened in for a while last night after installing the new gold screws... I think the reception improved! ;D

Greg,
I noticed that you don’t have the paint extending up on top of the face of the bass and in contact with the copper shielding on the face plate.  So, if you don’t  have a wire connecting the copper on the top plate to the paint in the cavity, then you don’t have a closed loop.  So maybe that is causing the problem.  Checkout the video on the attached Stewmac link, which might help.

Alternatively if the Cuban station he is picking up is playing some good Samba music... maybe just leave it as is?

HA! It's funny, because the station bumper music was my clue it was Cuban-based. That's exactly what they are playing. Until I heard the music though, it was just a Spanish-language radio station, and I could pick up a little of what was going on from my time with Mrs. Lambert, who tried her best to teach me Spanish in High School.  ;D

Seriously though, after the earlier pictures, I did do more overlapping shielding so that contact between the taped parts and the painted cavities was maximized.

After a short conversation with Mica the other afternoon, I found my trouble... couldn't figure out why the output of each pickup separately was okay, but when the selector switch was set in the middle for both, the output dropped to almost half, and the pickups sounded... well... just... bad. It was the connector to the neck pickup. I had to remove it to fish it through the wiring channel, then reattach it... and I got it backwards, which I reckon caused the pickups to be out of phase with each other when both were enabled, and the 'backward-wired' one to be noise and interference-prone. (I told you guys I was a Wire Dunce... I would fire myself, but then who would sweep the shop up?) Anyway, just swapping the leads around fixed everything at once. Even the Cuban radio station is gone. No noise, no hum, just the sweet and spicy sounds of an Alembicized Telecaster.

So I sent Mica a message confessing my sins and sat down to play Super-Tele... finally done. I'll post something as soon as I have something presentable. It really sounds great. Fun to play too!
