Welcome to

Your basic bauhaus BbL logo

I am pleased to say that the BassesByLeo forum continues to be a great place to discuss technical issues and options for G&L basses.  We also have modding information in Evil Experiments, a forum for non-G&L basses, and a forum dedicated to that G&L monster - the L-1000. 

We're also fortunate to have the company of Paul Gagon.  Paul has done extensive design work for Charvel/Jackson Guitars, Fender Musical Instrument Corp, and of course G&L Musical Instruments.  From pickups to preamps to amps and many other audio technologies, Paul has had his hands in the music industry for many years.  Now semi-retired, Paul has remained active with us a BbL as a teacher and technical writer.  He also plays a mean guitar (and bass, though he won't admit it).  You can find Paul's Technicalities here.

Questions emailed to me regarding G&L bass support or bass questions in general will be referred to the forum.  If you have questions about G&L basses and bass gear, please join the forum and ask there.  The forum is designed as a public place for G&L players to congregate and share knowledge.  Any back channel tech questions to me via PM or email will be referred to the forum, and it is common for me to copy & paste these to the forum.  I understand that there may be times when it becomes necessary to take a subject private, and I will make that determination on an individual basis.

You can find the new forum right here.  Please take a few minutes to check through the Announcements and the various forum descriptions.  Most of all, have fun!

Forum Registration and Activation

As of 5/4/2017, to reduce or eliminate forum spamming account activation will be done via administrator action. That means that I will be manually examining the registration details of all potential members and allowing access based upon the results of the examination. I verify that the email address used is valid and not a catch-all. Then I run the email address, username, and IP address against a spamming database. If I get a hit on any one of the items checked, I double-check using a different database. If I cannot get a clean read on all items, the prospective account is banned (email, username, IP) and deleted. If everything checks out okay, which is usually the case, the account gets activated. I'm generally able to do this within a few hours, but this may add a day or two to the registration/activation process. Once activated, I send an email to the address of record letting the recipient know that their account is activated and ready for use. If activation is denied for any reason, no email is sent.

Legal mumbo-jumbo.

Technical Stuff (in no particular order)

G&L and BBE wiring diagrams.  All kinds of nifty stuff for guitars, basses, and a few other things.

Here's a little piece I did on soldering.  Simple basic stuff.

Relativistic tone.  See IMPORTANT NOTE #1.  It's important.

Circuits to create passive G&L L series basses.  Yes, single coil is part of the picture.  There's also a nice little extra in there.

Early 1980s L-2000 circuits diagrams.  From the G&L "archive" and a modern re-do.

Jack replacement procedure for back loaded L series, ASAT, and JB-2 basses as well as ASAT guitars.  Maybe some others.  You know who you are.

SB-2 shielding tricks.  Details....

El Toro wiring diagram and a separate description sheet.  PDFs, so you'll need Acrobat Reader.

Bridge grounding.  Use your mind's eye.

L-2500/1505 Bridge Mod.  Sustain out the wazoo.  Updated 4/8/2010.

L-1500 / L-1505 / Climax wiring diagram.  With color coding, from G&L.

Notes on setting intonation.  It's a fat stringed thing, but probably good for the skinny stringers as well.

Wrenches for your G&L.  Of the Allen variety, from old to new.

Tweak that trussrod!  Info on how the CNC-era G&L trussrod does its thing.

Not so Technical Stuff

Canned Response.  Should have done it years ago.


Basses that are gone.  The reasons are varied, but gone is still gone.  I don't miss 'em at all.
