Re: Baja Music Man guitar and bass onboard preamps [documentation]

Any suggestions for a reasonably priced digital multi-meter that isn't junk?

Re: Baja Music Man guitar and bass onboard preamps [documentation]

I'm wondering how lead and tin go bad sitting is a closet? Probably the rosin core is what deteriorates but geez when I was a kid seems like a spool of solder lasted 10-years or you lost it... What do you clean your boards with? Do you prep your boards in any particular way? Are you an electronics g...

Re: Baja Music Man guitar and bass onboard preamps [documentation]

Jarno,

Did you know that solder has a shelf life? I have a 1-lb Kester .8mm (.031") 60/40 rosin core paper-weight manufactured Jul 07 17.

I guess I will not be buying any more 1-lb spools of solder, but before I go ahead and order less, I wondered if you had any solder thoughts or advice?

But in general, lower/smaller components before bigger ones.
I almost want to build my own tube amp now! :D

I'm looking forward to this it should be fun.

Re: Baja Music Man guitar and bass onboard preamps [documentation]

OSHPARK PCB boards delivered. That was fast! They look bigger on TV :D Ordered a DIY kit from Amazon to get some soldering practice before I jump in head first - its been a long time... And I am still waiting for the film capacitors to be delivered. Maybe by end of week I can solder one up and see w...

Re: Baja Music Man guitar and bass onboard preamps [documentation]

With all the different types of components possible for use on the OSHPARK board - how long do you think it would take a basic novice to learn everything he would have to know to be able to get on Mouser and develop my own BOM? I do not want to hijack this thread but I have about a billion questions...

Re: Baja Music Man guitar and bass onboard preamps [documentation]

Jarno / bajaman, I received some parts from Mouser - the Rev Audio 1M (treble) pot has solder lugs but the bass and volume pots are PC mount. I wonder what the reason for that could be? I think I can swap the 100k (bass) pot https://www.mouser.com/ProductDetail/313-1530F-100K out for this https://ww...

Maybe chose another 120pF RM2.5 cap? https://nl.mouser.com/ProductDetail/TDK/FG18C0G1H121JNT06?qs=sGAEpiMZZMvsSlwiRhF8qmOb354pYs68tl%252BbHxvNA420xESEAb0DXA%3D%3D Thanks Jarno, Ordered!

Re: Baja Music Man guitar and bass onboard preamps [documentation]

By the way, I had a look at the talkbass thread, which is mentioned in the OSHPARK link, and that has a mouser BOM which seems to work. The 4250 you need to source elsewhere, but other than that it seems to work, a few obsolete components for which they still have stock (and you could use that data...

Re: Baja Music Man guitar and bass onboard preamps [documentation]

Since I did my own boards, I do not know (mine are partly smt), but maybe wait until you have the boards and order parts at a hobbyists shop like smallbear? Resistors is usually not a problem, but the is some variability in electrolytics (tall vs fat, different leadspacings), and also film caps can...

Re: Baja Music Man guitar and bass onboard preamps [documentation]

A brief back story - not to derail a great thread. Built a Stingray clone with a mojo circuit - it sounded so nice I couldn't believe it. 16-months later the treble control was having no effect whatsoever. Mojo kindly replaced the entire circuit, and the bass sounded beautiful again. Some time later...

Re: Baja Music Man guitar and bass onboard preamps [documentation]

Jarno, Would you know if a National Semiconductor LM4250CN can be used in place of a Texas Instruments LM4250CN? I hope so because National Semiconductor is what I have. I apologize if this has been asked and answered elsewhere - I read through the thread but I do not recall. no problem at all - I ...
