Sounds great in a house.It also is a bit heavy to move about. Finally it costs WAY more then it should. ### ⭐⭐⭐⭐ Unbelievable Sound but a Couple Strange Problems *by S***S on Reviewed in the United States πŸ‡ΊπŸ‡Έ on March 4, 2013* Before I explain why I've rated this four stars as opposed to five, let me begin by saying this amp sounds AMAZING. There is absolutely no buzz and only has a barely distinguishable white noise when listening in a quiet space. Both bass and treble are super clear; I've never heard my keyboard sound so good out of an amplifier. Is it as good as a full PA system? No, but for practicing, performing in space with no sound system or even using it as a monitor, this amp is fantastic.There are four channels, all with stereo inputs and high and low EQ do not impede on each other's signals at all, allowing you to have four different line level instruments plugged in at once! One channel also has an XLR input for a microphone. Yes, you can play and sing and have it all amplified, along with a couple buddies to back you up. A fifth channel exists that can allow for a monitor input that plays a pre-recorded track or click track. Better yet, this channel can have output sent just to a separate headphone mix, so that you can play with a metronome in your headphones without it coming out the amp speakers.The amp also features send/returns for effects and pedal boards to either one particular channel or to all combined inputs or both. You can also connect the amp to another external speaker to create a real stereo sound if performing in a wide space or if you just need another monitor speaker. As if that wasn't enough, all inputs to the amp can additionally be sent via XLR outs to a mixing board and from there to a PA system, all with no discernible degradation of signal, allowing you to do volume and basic EQ mixing for a four-piece band right from the amp itself!I just completed a theater gig that lasted for three weekends, having my keyboard and an acoustic guitar plugged into the amp and the signal sent to a mixing board and out to the house speakers. It worked great, and we were able to use the amp as a monitor. I will certainly do a similar setup again.All right, so what's the problem? The amp is very heavy, which for the quality is kind of expected. However, the outer casing is in many places composed of a hard, dense foam material underneath the leather skin that seems to dent a little too easy. It is hard to set the amp down gently, even after rolling it (yes, it has wheels, but just two), and one of the stubs it sits on has already been dented into the foam shell and now it won't sit perfectly flat on a smooth surface. None of this has affected the amp's performance.The other issue is that I had problems with the sound crackling at times and even briefly cutting out entirely (not affecting the signal sent through the XLR outs). Peavey customer support can be slow and was quite unhelpful, asking that they or an authorized specialist take a look, which there was no time for, since the theater gig was underway. A friend looked inside and tightened the colored wires going to the 10-inch speakers simply by pushing them in a bit snugger. The remainder of the theater run went without a hitch and it appears the amp is working perfectly now. Perhaps things got loosened a bit in transport and shipping. I am bothered by Peavey not knowing of this ridiculously easy fix despite how detailed I described the problem to them. If the problem returns, I will update this review.The bottom line is that I love this amp, but have had a couple aggravating things happen regarding the denting, crackling and Peavey customer support. Really, this is a 5 star amp in so many capacities, but I would feel amiss to not share these stories in case anyone experiences similar issues. ### ⭐⭐⭐⭐⭐ The best out of (4) competing amps *by J***R on Reviewed in the United States πŸ‡ΊπŸ‡Έ on October 28, 2016* This is my 3rd keyboard amp in this price/watt range. I had a Crate amp that I gave up on 3 years ago. It developed a short in the main volume knob that I had fixed once, but the problems came back. It's still in my garage, worthless. I bought a Behringer Ultratone 45w to replace the Crate amp. This Ultratone amp seemed to have a lot of features, like equalizer, echo control, etc. But the echo control renders it worthless. The equalizer is redundant to the controls on the synthesizer, and need to be fixed at neutral anyway. I get tons of FX feedback. And it hums. Still, it works pretty well. Only, I didn't realize how bad the sound quality was until I put it side-by-side with this Peavey amp. I used the Peavey in conjunction with the Behringer as a PA system for a Halloween haunted forest this week. Between the two of them, we had plenty of sound to spare over a 10 acre forested area. The Peavey was clearly the winner. The volume on the Peavey was noticeably louder and we had to turn the Peavey down considerably to balance to the distortion level of the Behringer. The Peavey doesn't have a bunch of worthless 'features' to get in the way of quality sound and volume. It's solid, heavy, the knobs feel sturdy, and there is like NO distortion, even turned all the way up. I haven't connected it to a live keyboard/synthesizer yet, but as a PA system, it is fantastic for the price. It's a little more pricey than Crate/Behringer options. But way less than the Roland. I heard the Roland amp in my local music store, and it was solid, but its over $100 more than the Peavey. Having done the comparison of (4) competing models, this one is clearly the winner. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/7590356-peavey-kb4-keyboard-amplifier-multicolored-75-watts](https://www.desertcart.us/products/7590356-peavey-kb4-keyboard-amplifier-multicolored-75-watts) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-14*
