Caline CP-40 DI-Box for Acoustic Guitar

Good acoustic pedal, does what it is designed to do! I was recommended this pedal over much more expensive ones. I have used it now on about 30 shows, some inside some outside and 2 arenas. It works! Flawless in every detail, warm and rich tone, no feedback, and as a DI box it’s perfect!

So far so good. No complaints. I use this to compensate for my donner piezo pickups inside a cheap classical guitar. I use this pre amp to turn down bass and treble, because the piezos are a little noisy. Works great. I'm glad this worked out because everyone was recommending a pre amp that cost 3x the amount of the Caline. I couldn't swing it on my first project. I would recommend this for anyone doing a simple acoustic guitar pickup project, that just needs a good sound for practice, open mics and garage banding.

Great pedal. Does exactly what it’s supposed to. My only complaint, and it’s a niche one, is for my pedal board purposes the in and out are on the wrong sides. However when I’m using the xlr out for live gigs that’s a non issue. Definitely a great buy for the price point.

No difference at all with my setup: Alvarez acoustic >> Martin piezo pickup >> Cadine CP-40 (this item) >> Orange Crush Mini The hum from the ~$30 piezo pickup was not attenuated. YouTube videos indicate it works with an installed pickup on a better acoustic guitar. Videos also indicate it works better with the XLR output than the amp output. It is well built and easy to use. The 9V battery adapter is very handy for all my pedals and the Orange Crush Mini amp. I'll keep it for further troubleshooting. If I get it to work better with new additions to my setup or a friend's guitar, I will update this review. It's a good start if you have an inexpensive guitar and amp combo and you need to get more bass and treble adjustments. Anti feedback does work very well.

Much better than I expected it to be, considering the low price compared to "respected" acoustic preamp pedals I have used. Yeah, the IN and OUT jacks are in each other's typical locations, but it's no big deal. For this price, I don't think you will regret buying one.

I bought this and boy it just didn’t do a thing. I had to turn the knobs all the way up to get ANYTHING in the house. And the tone was muddy and terrible. This was with a D-18 with a K&K pure mini installed. So quality kit was there. This product just isn’t good.

It does seem to work as advertised for taming piezo pickups on acoustic guitars. But two major annoyances: First, no bypass. Never saw a pedal with no bypass. Not talking about true bypass vs buffered bypass, there is NO BYPASS! Note some other acoustic preamps at least have a mute switch. Second, the input jack is on the left, output on the right. Totally backwards and very annoying if you want to use it with other pedals. Especially since this should be the first pedal on the board. Third, no phase invert switch. IME, a phase invert switch is very desirable and effective for acoustic guitars. It can eliminate feedback, and also makes the sound of the amp blend better with the sound from the sound hole, from the player's perspective. Performance: there is noticeable hiss, even with no input. Granted you're probably not going to drive a high gain pedal with this, but IMO they should have used lower noise design and/or anti-hiss LPF.. Bass and treble controls seem to be at good frequency cutoffs, but I found I was turning them both to minimum to control the simultaneous boomy and tinny tone from the particular guitar I need it for, a 70's Guild dreadnaught with 3 parallel disks under the bridge plate. In the end, I found that putting my amp's bass and treble knobs at minimum and adjusting mid and presence I could get equally good tone. The anti-feedback feature does work. I can't imagine anyone needing the treble boost. Verdict: returning it. If the jacks weren't backwards I might keep it. If it had a phase reverse I'd definitely keep it.

Upon seeing this item, Caline preamp,I figured it would AT LEAST be worth a $40 risk....when I tried it through my Evolve 30m p a. system, I was blown away!!! The EQ controls are true- no harsh,droning bass tones, treble adds significant cut and clarity, notch control diminishes feedback! Plus, the DI out gives you everything you need for gigging. Ya, the "input" and " output" controls are on the wrong sides, but for this amazing value and sound, it's no issue at all.....well worth the price of admission!!!....

L’ho utilizzata poco prima di fare il reso perché a me purtroppo ha migliorato i problemi di feedback ma non risolti. Il mio problema era abbastanza grave quindi credo che su un feedback non esageratamente disturbante, potrebbe dare i suoi frutti. Anche l’effetto per migliorare il suono della chitarra, molto bello su chitarra acustica. Metto 4 stelle solo perché io non sono riuscito a risolvere il mio problema

Didn’t want to make a hole in my guitar so just used this and an under bridge pickup. Works fine

Realmente el producto me sorprendió, claro y si aumenta el volumen de la guitarra para pastillas mudas.

Lamentablemente estoy decepcionado y lo voy a devolver. Compre este preamp para alimentar una pastilla pasiva para una de mis guitarras acústicas, ya que al ser pasiva necesita tener más volumen para directo, a diferencia de las otras activas que tengo y que no necesitan nada. Pues al llegar el producto ya note al peso que no prometia mucho, pues pesa como un paquete de tabaco. Después al conectarlo lo primero, un soplo enorme, ruidazo desagradable. Y después y lo peor de todo, que no me da volumen a pesar de ponerlo a tope. No vas a ganar ganancia con este artículo, tienes que saberlo! El sonido es feo, alatado,resta naturalidad a el instrumento. entiendo que es un producto económico, pero también admito que hay muchas cosas económicas que están más elaboradas que está. En resumen... No hace su función. A no ser que solo toques en tu casa y enchufado a un amplificador, claro está que así no notarás nada, solamente tendrás casi 50 euros menos en tu bolsillo y un placebo para tu guitarra.

Leider als Gitarrist kann ich das Teil nicht benutzen. Billige chinesische Ton mit Rausch. Für Musiker kein Empfehlung.
