Something terribly wrong with my G&L. - Page 2

Stanley Design · #21 01-15-2007, 02:09 PM

Alright, I have an LM4250, and still just don't know what I'm supposed to do at this point, will putting an LF441 or OPA704PA in it's spot make my bass sound differently than it should? Are there tonal differences between the three kinds of chips, even if they all work correctly in that spot? Should I still be tracking down a G&L number to call?

Try to reach G&L but with NAMM this week that may be a challenge.

If there is a local electronics supply place ask them to try and get you a LM4250 or get an OPA704PA. You can, according to Dave, use a LF441 in the LM4250 circuit but not the other way around..

Ordered an LM4250 today.

Well, I got ahold of John today (G&L service). I'm supposed to send to beast back to them. I'm a bit worried about the price on a new preamp. He told me labor alone will be around $65-75. Shipping will be $30 each way.

Guh.

Greetings from the North,

Bite the bullet and go ahead and do it. It'll be worth it to get it done by John at G&L. Besides you can have the pleasure of telling your friends that your bass went on a trip to Cali.

It's going out UPS today. This will be my second G & L making the trip to Cali to visit John (my SB-2 is the first). I prefer to have them earning their way across the country, that way they can sightsee guilt-free.

The chip that I ordered came in, so I went to get it, he ordered something completely different, he said it was the same thing as an LM4250 but it wasn't even a chip at all. Back to trying to get ahold of G&L, can anyone help me out with getting me their number? This is already taking way too long to be fixed, and is effecting my ability to play with my bands.

I pretty much had the same problem as the original poster and a guy in another thread, and I ended up putting in a new opamp chip (the Texas Instruments OPA704PA) and that seemed to do the trick for me. It didn't take very long. I don't know much about bass electronics (never soldered anything a day in my life), but this was just plug and play. I just had to bend the prongs a little to fit correctly since they were a tiny bit wide. I would suggest this as a first course of action if anybody has preamp trouble before having to send a bass back.

John gave me a call last Wednesday. He says a whole new pre-amp is needed. Cost? $175.

Guh!

It wasent covered under the warranty ?

quickervicar · #31 02-27-2007, 08:08 AM

Nope, it's out of warranty. I just was hoping that it wouldn't be that much. I'm trying to bring this bass back from the dead on-the-cheap and this isn't helping.

As a side note, John @ G&L was very good to deal with.

Before I send mine away I might just get them to send a new preamp and bite the bullet. 200 dollars for that might be cheaper than renting a suitable replacement while it's being repaired plus shipping on this ride from my house to the factory and back, look at how far it is, pretty much as far as can be.......

And here I thought you were a Newfie!

Got my L2k back on Friday. Plugged it in & it sounds great. Even better than my ASAT. Different pots & switches, judging by the action on them. Much stiffer, more like a good sound desk. (yes, I know that they will loosen up a bit, but this is beyond that)

Hooray! Result!
