Update on my bass uke piezo pickup mods

When I discovered the Korean made ($85) all metal fully adjustable bass bridges with individual piezo pickups in each saddle, I had Eric's Guitar replace on my solid body bass ukes, and now on my violin/Hofner knockoffs, the semi adjustable wood bridge with a piezo pickup assembly that had unbalanced output, which I had to fix too often. Being piezo, the new bridges also allowed me to use the same flatwound nylon core strings.

Those new bridges started out fine, but as I bought more, one or another of the saddle pickups was unbalanced and Eric had to scavenge a saddle from a donor I had to buy, which was a pain for him. I looked for alternatives and could only find the GraphTech Ghost piezo HipShot bridge ($245, and looks very much like the Korean), I ordered two, but both of them had an unbalanced saddle. Both Eric and I tried to make them work, but no go, which was very frustrating.

I then asked Eric if a magnetic pickup can be used, like on a real Hofner. He immediately said, "Yes, much better way to go." I asked if that would be a problem with the preamp, nope, he said. I ordered from Amazon mini humbuckers ($20). As I waited for them, it occurred to me that when Eric converted a small scale electric guitar to a small bass, the flatwound nylon core strings did not have enough metal, so not enough volume output. I had to have Pyramid custom make 23" scale all metal flatwounds.

I contacted Pyramid to put in another order, but their reply was delayed. In that delay, Eric installed the magnetic pickup with the nylon core strings, and to both of our surprise, they picked up perfectly fine. Apparently the mini humbuckers are hotter than any of the existing pickups in the guitar conversions.

He's done two of the Hofner style bass ukes, and I have two more with bad bridges, a Korean and a GraphTech, plus I have four more new bass ukes that will get a magnetic pup right from the start. Only if or when any of the other Korean bridges go bad will they get a magnetic pup.

Wow quite a collection you have gathered over the years! I'm just getting back into playing after about 10 plus year long break! I remember when you first came to the forum and asking about ubasses and I had just got my Kala and I also remember recommending the Carvin micro bass amps to you! I just built a cigar box ubass recently. Here is a picture next to the Kala and my new shortscale Gretch.

Long time 1stnamebassist, I didn't know you replied, just saw this. To make sure I'm notified of the reply, either like or quote my post, or use an @ before my ID; @KohanMike. Your suggestion of getting the Carvin MB15 amp got me to do it, very happy with it, thank you. I've actually gone through 45 bass ukes/mini bass guitars in the ten years of playing bass uke. About a year ago I found that I'm most comfortable playing the Hofner style RondoMusic Hadean with nerve damage to my neck spinal cord from radiation treatments for cancer in 1973, so I got rid of all these others.

Nice collection of yours, cigar box is a great use of bass uke parts.

I remember my first bass was a violin bass, probably Japanese made called the Blackjack bass! It was my brother's and he never used it, so my folks thought that it would be a great idea for me to learn an instrument to refocus my life onto a better path I guess, and they asked what I would like to learn to play and I immediately said bass! I always noticed the bass player every time I saw a band, I liked the look of the massive bass and I loved the massive low end! So at 14 years old I started taking bass lessons. Not liked today with backing tracks and free lessons online, it all began by reading music, very traditional learning the first couple years. Anyway the point is I've always had a soft spot for violin basses, even though currently I don't have one. Maybe a fretless Harley Benton beat bass will come to live with me at some point. I wish I had that old violin bass now. The other thing I wanted to mention was a site called mgbguitars.com. They sell cigar box guitar parts and kits. That is where I bought the neck and bridge with pickup and preamp for 80.00. They recently came out with a fretless neck also. I thought you may be interested or know someone who may be interested in these kits. They also have 30" short scale and 34" long scale bass necks as well 3,4 and 6 string cigar box necks and ukulele necks etc… anyway, take care my friend!
