How to choose the best keyboard amps
Power (Wattage)
Don't be fooled by numbers alone. 20-50 watts is generally enough for practice and small gigs, but headroom is key. More wattage doesn't always mean louder, but it can mean cleaner breakup before distortion, which is important if you like a little grit.
Speaker Size & Type
A 10" or 12" speaker is the sweet spot for keyboard amps. Look for speakers designed for flat frequency response - you don't want a speaker that artificially boosts certain frequencies and messes with your keyboard's voicing. Woofer/tweeter combos can help extend the frequency range.
EQ Controls
Basic EQ (bass, mid, treble) is a must. A mid-sweep is a huge bonus - being able to dial in that fat midrange honk or cut through a band mix is invaluable. Without decent EQ, you're stuck with whatever the amp's inherent tonal limitations are.
Connectivity
XLR input is a big plus for connecting to a mixer or mic. Auxiliary input lets you play along with backing tracks. Line output lets you send the signal to a PA system. Consider what you'll be connecting to.
Portability
Keyboard amps often get lugged around. Weight and size matter, especially if you're a solo act or frequently gigging. A lighter amp is a happier back.
Buying guide
Alright, so you need a keyboard amp but your bank account isn't screaming five-figure prices. It's a common situation. Getting decent stage volume and a usable sound for practice or small gigs doesn't require breaking the bank, but you need to know what to look for. We're focusing on amps under $300 - that's a tough budget, but we'll find you some options that deliver more than you'd think.
At this price point, you're making trade-offs. Don't expect pristine, studio-quality sound. Expect functional, gig-worthy amplification.
Corners will be cut - often in speaker quality or the sophistication of the EQ. Prioritize EQ flexibility and a flat-sounding speaker over raw wattage. A little extra weight for a better speaker is almost always worth it.

Questions
Will a $300 keyboard amp cut through a loud band?
It's tough. You'll likely need to mic it up to the PA. Some amps with a bit more wattage and a decent tweeter will fare better, but don't expect miracles. It's a band rehearsal amp, not a stadium amp.
What's the difference between a keyboard amp and a guitar amp?
Guitar amps often emphasize mid-range frequencies to make guitars 'cut.' Keyboard amps should aim for a flatter response to accurately represent your keyboard's sound. A guitar amp can work, but it might sound honky.
Can I use a keyboard amp for recording?
Sure, but it won't be a direct replacement for a studio monitor. The sound will be usable for demoing or rough tracking, but the speaker quality won't be as accurate as dedicated monitors. Line out is your friend.
What does 'headroom' mean in this context?
Headroom is how much louder the amp can get before it starts distorting unpleasantly. More headroom means cleaner sound at higher volumes. It's especially important if you want to use effects pedals.
Are combo amps (amp + speaker) always better than a separate amp and speaker?
For portability, combo amps are often more convenient. But if you're serious about sound quality, a separate amp and speaker can offer more flexibility and potentially better components, though it's rare to find a great speaker under $300.
