Here are some examples of what your guitar or bass could do!


Strat series tone mod


Imagine being able to play your strat stock and when you need it roll the middle tone knob down and play the middle and bridge PUs in series like a higher output humbucker! with no strat hum!

If you want that big jazz sound switch to the neck and roll back the middle tone and you have a series humbucking PU for huge tone! All with stock new parts!

"You ain't played a strat till Big John puts the MOJO on it!" Wildman

Series tone mod for

Gibsons (depending on PUs)...

Now this is a versatile mod. The top tone knob is used to blend the stock sound with the series sound. Tone all the way up is stock sound. Tone all the way down is all four coils in series for a huge solo sound. In between are some of the coolest sounds a les paul, SG, or 335 ever made. from a tele to an out of phase funk machine! This mod turns a gibson into a do it all wonder guitar. No visible change to the instrument.

"The series wiring you did on my Les Paul is unbelievable. I can get so many sounds and more tone than before. The coolest sound is a blend between series and stock that sounds doubled like two guitars playing. Thanks Big John!" Craig

Tele series mod

 This mod uses the stock 3way switch to play both PUs in series in the middle position instead of the weak stock sound. So now, when you step up to solo let them feel it! Same PUs same switch big tone! "Man my tele is kicking butt with the switch rewired. thanks." Dustin

Dual coil tap pan for Gibsons  This mod uses one of the tone knobs on a Gibson to pan from humbucker to single coil on both PUs. No new parts.

Now you can get all the twang and sparkle you want from that rock n roll machine.

Series mod for jazz bass

This is a must for J basses. No more thin tone. This mod uses one of the volume knobs to pan from stock sound to both PUs in series. Now your J bass will get that big humbucker tone. The blend in between gets the scooped parallel sounds as well.

"Wow the J bass is playing so good now and the series push/pull sounds so rich it's all I play." Jason

This is just the tip of the iceberg.

This has been in the works for many years! Hopefully I can eventually accomplish it.
