when I was talking about adding "legs" to the crystal I was referring not to solder a big braided copper cable, which is difficult and not very practical. I would suggest you try instead with resistor legs. Just clip both wires from a resistor, as long as possible and use those instead. use alligator clips to hold the contraption while soldering.
Those wires will create a pointy and easy to solder junction to both the crystal and the pcb, and avoid the flexibility of the cable you are using which will play against you while mounting the whole thing together.

Soldering ugh!!!

Let's see, I just pull out my:

1. Cardboard for table top
2. Extension cable
3. Surge outlet strip
4. Lamp
5. Weller soldering iron
6. Holder for soldering iron
7. Solder
8. Wet sponge with multiple slits in it
9. Extra hands apparatus
10. Exhaust fan (although I think I read somewhere recently that breathing
lead actually might be good for you)
11. Long needle nose pliers
12. Short stubby needle nose pliers
13. Wire strippers
14. Magnifying glass
15. Safety glasses
16. Multiple types of heat shrink tubing
17. Heat gun
18. Large wire cutters
19. Small wire cutters
20. Shield unthreading tool
21. Box cutter knife
22. Vinyl electrical tape
23. Fluke multimeter
24. Connectors
25. Cable

It is no wonder why I love soldering and the smell is just,...just
breathtaking. Oh, and my back gets this incredible workout. NOT!!!

LOL...

I keep #1 against the garage wall (it's actually a smallish sheet of Masonite) and #2 through #25 are in a box on the shelf. And, yes...oh that smell!

Cheers.

I love the smell of solder in the morning.

:lol: I use my always connected soldering device (yes, it has an on/off button), which has its own place at the indoor workbench :) But up till now it has mainly been used for cabels and larger things... ...and I happen to like the sm.. aroma.

Yeah I like the smell too - feels all scientific to me (that'll be from where I first smelt the stuff in a nerds lab at school - it's the flux we can smell)

Now I have cut the legs from an unused resistace, grinded the stumps of the crystal, put a dot of I-don't-know-the-English-name-for-the-soft-metal-thred-you-melt on each stump, fixed the crystal and left the workbench for a deep breath, a beer maybe, and a good eye rest. I think I'll wait a day before I do the work. It's almost a week until the next gig anyway! :lol:

Its called 'solder'
Just be careful when doing the other end, that what you have already done does not fall off. The heat can flow up the wire and melt the bit you've done!

If you have a small clamp, alligator clip, etc, that will act as a heat sink and limit how hot the other end gets.

And yes...taking breaks between steps...and including a few beer, can take away some of the stress.

Good luck, you are on the path to success...we hope.

Cheers.

Thanks! Also, it's Friday night here in Sweden right now. I guess you have a lot of day left yet :-D

couple of tips:

-use as little heat and solder as possible. ideally add a tiny drop of solder to the resistor leg and crystal SEPARATELLY and then just put the pieces together and apply heat, just a split second is more than enough.

-once your crystal has the new legs, the tricky par is to solder to the PCB without desoldering the crystal from the legs. For that make sure you hold the crystal with pliers from the new legs, so the pliers will act as heat disipation while you solder the legs to the pcb and the legs will not desolder from the crystal. again before doing this apply some solder separatelly to the crystal legs and pcb, then just apply heat to both together for a split second

usually the biggest hurdle are the shaky hands, so use alligator clips and you should be done in 10 minutes

^^^ And that's where the beer helps :D

NO...I would never recommend soldering under the influence...

Take your time, take deep breaths (away from the solder flux fumes), and you'll be fine.

Actually...if you aren't very skilled in the art...you might attempt some practice with some spare resistor leads and something else...just to get the hang of how little solder and how little heat you can apply. It is a bit of an artform that takes years. So take your time and you'll be fine.

Cheers.

Well... So I managed to solder two short legs, and solder the crystal back to the PCB. I swiched ON, and the former dead display went on, the programming I had done still in place, footpedal working, great happiness. Screwed the whole thing back in my rack and plugged in a guitar. SILENCE! Not even a hush from the speaker cabinet. :( Out with the amp again - on the workbench - plug in a speaker and a dummy tele to check noise. A little poking with the circuit and there was humming in the speaker. Peeled of the crystal and started all over again. Two days of soldering and some bad language made me give up.

A new PCB will cost about twice as much as I paid for the amp. I think I return to my old one-sound-workhorse-Music Man and stomp boxes instead. :(

The good part is that I found this forum, and you helpful guys! :) But if a miracle doesn't happen, I'm not a Fender player anymore and will probably not hang around here in the future.

Thanks a lot for all help!

That's a shame. You make it sound like a fault with the amp itself, which doesn't seem to be the case. Whereas I empathise with your plight of having a broken amp, it appears (unless I'm mistaken?) you had a perfectly good working amp until you took it apart and broke it? Sorry that happened, but it seems wrong to make a decision about a product (and from your last comment, about a company's entire product line?) based on that.
