Pickup experiment – bypassing electronics

Speaking with Pete Biltoft at Vintage Vibe Guitars about possible dog-eared P-90 pickup replacements for the Riviera P93, Pete recommended I first try bypassing the guitar’s electronics to see if they’re sucking the tone away.   This experiment requires disconnecting the pickup wire from the electronics, and routing it directly to the output jack.  The results are interesting.   Read on for pictures, and audio, video before/after.

IMG_3188 Gathering my tools, started to feel a little crazy!   Soldering iron and solder, needle nose pliers, locking pliers, big and small phillips screwdrivers, wrench, wire stripper, multi meter, alligator clips, 1/4” jack, magnifying glass, flashlight, tuner, string winder, spool of thread, soft cloths.

I did all my work on the floor – bad idea!  Why am I always too lazy to clear off a table top before starting?

A Luthier’s Setup

The factory setup of my Epiphone Riviera P93 was horrible!   I had a luthier to do a full setup on the guitar, and it’s much better now.  Read on for all the measurements before/after the setup.

Prepack ChecklistHere’s the “Pre-Pack Checklist” that came with the guitar.  What a joke! I imagine the inspector works like this:

  • Intonation?  Sucks, check!
  • String height?  Crazy high, check!
  • Buzzing?  Yep, check!
  • Fretboard cleaning? Yuck, check!






Well, Mr. 24 in the USA, I’m not impressed!




Here are my measurements of the lousy factory setup:  Read the rest of this entry

Video Review of the Epiphone Riviera P93

Just uploaded my first YouTube video ever 🙂  It’s a quick overview of the Riviera P93, along with some demos of the three P-90 pickups individually, and my thoughts on possible mods/improvements.

I’ve got some more videos and audio examples, coming soon, so stay tuned…

Possible guitar mods

There are several things about the P93 that I’d like to change.  The pickups seem dull and lifeless.  The wire retainer on the Tune-O-Matic bridge rattles and buzzes, so I’d like to change to a better bridge.  And I hear occasional pinging in the nut when tuning and using the Bigsby, so perhaps I’ll change the nut to a Graphtech teflon nut.

I often read folks saying that a new nut gave them better sustain, or richer sound.  Or how a new bridge gave them less high frequency response, etc.    It all sounds a bit wishy washy to me.
I’d like to be more scientific about it.  For each mod, I’ll do some before/after recordings and post them here.
