Good guitar models. Seems much better than the previous units I have owned (A2 and A3).Lots of EQ options. I was surprised to to find a Boss equalizer, Fishman EQ and Baggs EQ. Effects seem to be good and most of the presets are solid. At least good base settings to give you a head start.I found the user interface a little challenge in the begining, but after a short period, it was easy to figure out.I don't use a Looper for live use, but it works great to adjust EQ if positioned pre EQ.One of my favorite functions is the ability to use a bank of 10 in a series. In other words you set it to start at the beginning (say #10) of the bank and after 10 set points, it starts over at 10. Good for setting up different guitars in Each bank.Each preset has the ability to set the level, which means you can adjust the output level for different guitars.Also, the models have a gain setting for each, which means you can somewhat control the level/effect of the model.Really liking it so far. Easy to reach good, natural sounding tones with each of my guitars. ### ⭐⭐⭐⭐ Great EXCEPT Looper *by M***T on Reviewed in the United States on 27 October 2023* The effects on this pedal are great for getting a variety of sounds out of your guitar. If you play sets with a variety of genres you should get it. I play everything from Prince to Tom Petty and Toby Kieth. I like switching between the presets to adjust to the feel of the songs I’m playing. I don’t like the looper function because you have to use your finger to activate it. It would be much more functional if you could get to it on the fly with the foot pedals. You can always buy an additional foot pedal but it’s just another thing to pack. ### ⭐⭐⭐⭐ Bueno, pero complicado para instrumento acústico. *by Ó***S on Reviewed in Mexico on 14 February 2023* Interesante pero complicado para los fines que puede tener un instrumento acústico. El adaptador de micrófono hace mucho ruido. Aunque da buenos sonidos, es un emulador que no completa el tono natural de un instrumento acústico. ## Frequently Bought Together - Zoom A1 Four Acoustic Instrument Multi-Effect Processor - Zoom AD0016D Power Adapter - co2CREA Hard Carrying Case replacement for Zoom FOUR Bass Guitar Multi-Effects Processor Pedal (Zoom G1 B1 A1 FOUR Bass Guitar Case, Black Case) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/425731836-a1-four-acoustic-instrument-multi-effects-processor-pedal-acoustic-modeling](https://www.desertcart.co.th/products/425731836-a1-four-acoustic-instrument-multi-effects-processor-pedal-acoustic-modeling) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
