GUITTO GGP-04 Acoustic Guitar IR Vibration Pickup with Multiple Classical Guitar IR Tones, Multiple Reverb Delay Effects, Precise tuner & color LCD display

Works great, still on original battery after extensive use. Now installing my second GGP-01. Negative reviews generally based on incorrect assumptions. OK, it is a bit misleading when the ad says "no need to drill holes" they mean no need to expand the size of the soundhole, as you often must do with the regular S.H.P.'s which span the diameter. This one just clips in on the side. My Fischman required annoying resizing of the soundhole and has no provision for running the cable through a hole at the bottom of the guitar body. Now you can certainly loop the connecting wire through the sound hole if you absolutely don't want to drill into your guitar but the basic design is predicated on the presumption that you will drill as follows:(1) take out the end pin on the bottom of the guitar where you loop your guitar strap; resize it to accept the pickup output jack (female jack). That is a bit of a pain, I used increasingly larger drill bits Ideally you would finish with a round file. Be careful not to drill too large of a hole or splinter or crack the wood. It is not difficult if you take your time and use your head.(2) You also should drill a tiny hole (2.5 mm afaik) on the bridge and then you put the "piezo pickup", which looks like a wire (OK, it IS a wire) underneath the saddle (the little bone or fake bone plastic deal that your strings run over). String tension or ideally the grip of the bridge on your saddle then hold the "piezonpickup" in place; the male jack on the end plugs into the clip on main portion of the pickup. Now it is also possible to skip this step (2) entirely and if your run the wiring out of the soundhole you can test the "microphone" part of this pickup without drilling. Then you can decide whether or not to drill your guitar. Now I will not drill my vintage Ibanez lawsuit Concord acoustic, but I have no problem drilling out most of my Asian production line acoustic guitars.This MAY work on some larger ukeles if and only if the arc of the buckle can be fitted. Maybe bass or baritones but don't take my speculation for it...if you make a ukelele out of a small parlor guitar maybe that would work. I have not tried this on parlor or concert size guitars but probably would work. I have it installed on the next size larger guitars and presumably the buckle will clip onto a wide range of sound hole sizes. I suppose it would be possible to tweak the curvature of a sound hole on a smaller guitar or ukelele but any such experiment would be at your own risk.The sound is surprisingly good generally as used on my Roland STREET and similar battery powered guitars.I have another pickup of different make and design which has little cylindrical metallic microphones plugged into the main body of the pickup, which uses the diameter-spanning style, but I prefer the Giotto because you don't have to worry about the little microphones getting lost - this is mainly a guitar microphone with a bonus piezo - which is ideal for nylon string guitars which don't work with magnetic pickups such as you probably have on your acoustic electric steel strings.Nothing will approximate a studio-quality instrument mike up close in a proper acoustic environment. .But this Giotto does not pick up a lot of background noise at all and feedback, while occasionally an issue, is quite managable.The main drawback to this item is that if you are a klutz or have a very nice vintage guitar you might mess up, installation is not entirely idiot-proof But if you are handy with drill, files and screwdrivers, or are willing to pay a moderately competent shop to install, this pickup is pretty decent for the price point.I am a third generation musician jack of all trades master of none no warranty or guarantee that my views can be relied upon please consult your luthier and weigh all of the published reviews.

It works. Installation was pretty simple. Put this in a Yamaha 12 string. The piezo mic was a hair to short but still usable. The sound hole mic part sounds great but it feeds back a lot. The phase button helps a little. The tone control seems to either make the sound bright or dark, no real control. Id put this in a cheaper acoustic again but for a higher dollar guitar I’d steer clear.

It sound really good for what it cost. It’s easy to instal.

Background, I have a 6-string Martin DX1RAE and an old Rogue 12-string. I was going to replace the pickups in my Martin with this pickup system, and then use the old Martin pickups in my 12 string.Unfortunately, this Martin uses a lot of bracing inside the body near the sound hole, and there was no where to clip the pickup into the guitar that was free of bracing. It just flat-out wouldn't fit. I thought about returning it, but ended up using it in my Rogue 12-string, and it works great there.Yes, you do have to drill a hole into the under-saddle of the bridge if you've never put a piezo in there before. I used a 7/64" bit and it was the perfect size. All the other connectors work fine, and it came with 4 CR2032 batteries. I haven't used it long enough to tell how long the batteries last.Overall, it's fine, but had to dock points because the description doesn't mention anywhere that it is too big to the point that it won't fit some guitars.

Installed the electronics, input jack, and under saddle pickup. The under the saddle portion appears to be inoperative.

They promised a plug and play device. IT IS NOT. I ordered one, it didn't work, so a ordered a replacement, it didn't work either. E tested with different batteries just in cases, no sound at all. That's when I realized that you have to drill a hole on your guitar and use the cable on an amplifier to work. If i have to drill a hole on my guitar, i would do to a better device, and not this one. I just bought this one too avoid drilling my brand new Cordoba guitar... The ggp-02 requires to drill, but it is a very Superior device.

I have an Epiphone AJ-100CE that I bought in 2007 that is really a great guitar. Problem was, although an Acoustic-Electric, it did not have onboard electronic sound controls ... just a straight line wire from the under the bridge piezo pickup to the output jack. Hence, before I bought this Guitto Guitar Soundhole Double Pickup, I had been shopping to purchase an onboard electronic control setup, which would ultimately involve cutting into the body of my Epi. This was concerning to me.However, in researching I happened upon the Guitto Guitar Soundhole Double Pickup. Wait ... Everything I need without needing to cut into the body of my Epi? Wow! So, in watching the video I was further (and so very) impressed by the sound and tone emitted by the Guitto Guitar Soundhole Double Pickup, I bought it. Once it came in and installed it, the sound and tone was even better in real life.In short, I am so very happy that I did find and buy it. Therefore, I cannot help but to highly recommend the Guitto Guitar Soundhole Double Pickup, and write ... "GREAT JOB GUITTO!"

This is the 3rd one of these I’ve used. I installed one in my personal Taylor 12 string and love the sound. The reason I gave only 3 stars to ease of installation is, it takes some experience to install it properly. I build and repair instruments as part of my living, as well as perform in local venues. I have been installing pickups in acoustic guitars since the mid 70’s, so I know quite a bit about finding an accurate acoustic guitar sound and the proper way to install pickups. The end pin jack is a bit tricky to keep it from coming loose and spinning around. The larger threads should be about 5/64 below the surface before tightening the retainer nut and a pair of round nosed pliers really helps install the strap hub without damage.

I had to drill a hole in my guitar....but everything thing else is perfect

The sound is a huge step up from my previous SA-1 sound hole pick up. It sound much more real and really makes the picked up sound acoustic (as opposed to an electric).You have to drill a couple of holes if you wan the full integration but it is well worth the effort. The quality of the unit is good. Just hope it'll last.Note, if you intend to use the output jack as strap holder, you'll likely need to enlarge the strap hole a little so it doesn't pop off.A good purchase in my books.

Ce fut un beau projet pour moi facile d'installation et facile a utilisé beau son et a une belle apparence
