Not your average acoustic bass pickup!

Comments about Lace USAB Ultra Slim Acoustic Bass Pickup:

I bought this pickup to retrofit my Olympia OB-3CE acoustic bass. The original electronics in this bass shorted out years ago, and while I had them professionally repaired, the replacements never did justice to the instrument's tone, and I ended up stripping them completely out. When I saw this new Lace pickup, naturally I was curious: would I finally get my bass -- a 17" jumbo monster -- to sound as big as it looks? It was worth a shot, so despite the lack of available sound clips or reviews I splurged, and thus far I have no regrets.

Installation was as straightforward as promised: just find where you want to place the pickup, peel the plastic off the adhesive tape on the back, and stick it on. Depending on your bass's setup, you may need to raise your action somewhat. This pickup is indeed slim compared to a standard electric bass pickup, but it's still about twice as thick as a typical slab fingerboard, and space will be cramped underneath the strings regardless. Removing the pickup is also straightforward; grab it firmly by the edges and twist it off. (Don't attempt to pry it off, or you risk denting the top of your bass.) I've moved the pickup on my bass several times to find the right placement, and the 3M adhesive left no stains or residue on the finish, again exactly as promised.

Pickup placement is something of a dark art. Too close to the neck, it becomes muddy and you risk lower strings "fretting out"; too close to the bridge, it sounds brittle and lacks low-end power. After trying several positions I eventually settled on 4 3/4" from the 20th fret to the top of the pickup, or 5 1/4" from the 20th fret to the center of the pickup -- slightly lower than a P-Bass's pickup at 5" from 20th fret to center. I installed my pickup backwards, with the "Lace Sensor" label upside-down, so I could run the pickup cable cleanly into the bass's soundhole.

Which brings us to the fun part: the sound. Because it sits so close to the strings, this pickup is LOUD. Recorded direct, it's frankly a bit dull, flat with some "clickiness" on the string attack. But run it through an amplifier and it's a whole different story. This pickup is extremely prone to feedback, giving it a thick, muddy bottom, but with surprisingly good clarity on the high end. It's something like a cross between a Jazz Bass and an EB-0, with a little bit of piezo-like snap. At any rate, it's a distinctive sound, and one I've never heard from any other bass. It's not as easy to work with as, say, a Fender's sound, but I suspect it will be a very rewarding one once mastered.

That said, this is obviously a "version 1.0" product, which is why I have only given it four stars out of five. No wiring diagrams were included with this pickup, nor any other documentation save a warning card about the adhesive tape. The pickup includes a built-in, non-removable endpin jack, which I find puzzling since the majority of acoustic basses sold are electro-acoustic models, and I imagine post people buying this pickup are looking to retrofit an existing bass. I had to resort to some frankly horrific wire splices to run this pickup through my bass's existing endpin jack; it should be much easier to hook this pickup into existing wiring, or possibly a volume control or pre-amp.

Overall, this is an interesting pickup if you're looking to try something different or just can't stand that tinny piezo sound. As a magnetic pickup, it hardly delivers a faithful acoustic tone, but I see this as an advantage: it goes beyond delivering my bass's unplugged sound writ large, creating instead a massive sonic presence to echo and even rival this voluminous instrument's looks (less florid descriptions may apply). I'm tempted to buy another now and run my bass in stereo. After all, who said "acoustic" instruments couldn't get loud?

      Comments about Lace USAB Ultra Slim Acoustic Bass Pickup:

      When the piezo pickup on my '93 Ovation CC74 AE short scale bass finally gave up the ghost (after never being much good anyway), I began looking for something to give it new life for practice and home recording. Based on reviews, I ordered this lace USAB and set it up by placing it an inch back from the sound hole (2 inches from the bridge). I used the adhesive and just let the cord run beneath the strings and around the bottom strap post and secured the jack to the strap. I may end up permanently installing this inside the body but this temporary setup has been working fine for a couple months now.

      The end result is that I now have a brand new bass! Whether going direct to my amp or through a USB interface to a DAW on my MacBook Air, with this pickup and D'Addario tape wounds I can make my CC74 sound like an upright or give it a Hofner sound and I am still experimenting with the whole new range of tones this pickup has unlocked from my bass. Highly recommended for AE's with dead or anemic piezos.

      Comments about Lace USAB Ultra Slim Acoustic Bass Pickup:

      I got this for my 1971 Gibson EBO bass because description here says for acoustic or solidbody. Before ordering I couldn't find any video or pics on the net to see how to install it. When it came there are no instructions. That's ok by me as such but the cable and endpin are permanently attached to the pickup.I didn't want to cut into it to put it in the bass internally so I mounted it halfway between the top of the bridge and bottom of the fretboard with screws. Its raised up to the strings and theres a gap underneath but this is the only way to get the sound and volume I want. The cable is wrapped around the bridge then down the body towards the back of the bridge and the endpin is secured there with screws on either side. Since its not spliced into anything theres no volume or tone, just plug in and go. Yeah I know that's really cheesy but it does really sound good! I used it in church sunday and got complements on sound. I use the amp to set tone and volume and turn amp all the way down before plugging and unplugging.I did have to run a wire from the metal at the back of the endpin to the bridge to stop some treble hiss.I know most players would not accept this. To be done right it needs to be wired in but Id need to pay someone for that,maybe later. Im pleased with the sound. The EBO has a good playing,low action rosewood board and with this pickup its a clean,clear,punchy sound that's not woofy. I leave the amp settings {various GK,and Peavy} pretty much flat with maybe a little extra bass and treble at times. Id been using this bass {I have others} in the house for practice but now I can play it out and sound good.
