A: Assuming your keyboard is a modern one with sampled sounds, don’t buy a keyboard amp at all. Just buy a small PA.
If you are playing a vintage instrument, the purpose of the amp is to CHANGE the sound. Usually you are trying to “warm it up” with tube overtones, such as with a Rhodes or Wurlitzer piano played through a Fender Bassman Ten or other vintage tube amp, or to create a chorus and vibrato effect such as playing a Hammond organ through a Leslie 122/147. With a modern instrument, all that is already built in with the samples and effects in the keyboard, so the only purpose of an amp is to make it louder. That’s precisely what a PA system is designed to do. They are designed specifically to NOT CHANGE the sound. For this reason, modern keyboards seldom sound as good played through a “keyboard amp” as they do through a small, high quality PA system.
My favorite keyboard amp is the Bose LS1. Keyboards sound stunning through it, but it’s pricey. On a budget, just go to Sam’s Club and buy an ION Total PA Max, or one of their smaller units. You’ll spend less and sound better than buying a "keyboard amp."
Q: How
do you deaden the sound of a baby grand piano
besides closing the lid and holding the soft pedal
down? It's bothering the neighbors.
A: Buy a Yamaha
P-515 and a pair of Sennheiser HD280Pro
headphones. Plug the headphones into the P-515,
close your eyes, and you’ll swear you’re playing a
9 foot concert grand… which sounds WAY better than
your baby grand… and the neighbors will never hear
a thing!
Response to
Irv's answer from Howard Miller: I agree.
My wife is a professional musician. Years ago,
we had a couple of upright pianos, but as I
got older, I came to hate having to move the
things. We got rid of them and we got a decent
digital piano. She complained about it, but it
worked well enough that she could practice. It
has two foot pedals instead of three, but as I
understand it, the third pedal is pretty
unused. It can reproduce what sounds like a
decent grand sound, an upright, harpsichord,
and organ. No organ pedals, but she mostly
uses the upright mode. I don't doubt her
complaints, but I can move the thing all by
myself.
Irv's
response to Howard Miller: Yamaha has made
AMAZING progress in digital pianos in the last
few years. If you were to buy your wife a
P-515, I doubt you’d hear her complain again.
The action is nearly indistinguishable from a
Yamaha 9 foot concert grand, complete with
“escapement” and “graded hammer action.” The
tone is so good through headphones that you
can get lost in the music... and it’s
surprisingly decent through the built in
speakers (considerably better than in the
past). If you get the optional stand made for
the P-515, you can get a three pedal option
that works and sounds exactly like the three
pedals on a concert grand (which work quite
differently from the pedals on your old
upright pianos), including that the damper
pedal is not an on/off switch but rather is a
continuous pedal that can partially dampen
when partially pressed. The keys don’t feel
like plastic, they feel like wood and ivory.
It even has the sound of sympathetic string
resonance and mechanical damper sounds. I’m
not kidding, if you bought your “decent” piano
more than five years ago, the P-515 is at
least five times as good as the one you
bought. The P-515 is not a pretty piece of
furniture like a Clavinova, but at $1,500 it
is an affordable price, it sounds just as
good, and it’s less than 50lbs. If you have
money to burn, the bottom end CLP
700-series Clavinovas sound just like the
P-515 but with a nice piano-looking wood
cabinet (and still
only need two people to move).
They sell for $2,000 to $2,700. And the
top-end CLP Clavinovas sound even better than
the P-515, and sell for $3,500-7,500.
The most expensive ones even look like a small
grand piano.
Q: Are
digital pianos as good as real pianos?
A:
That depends on your definition of “good.” If
“good” to you means it sounds like a 9′
concert grand, and you can play it without
bothering neighbors, and you can move it
easily when you move to a different house, and
it never needs to be tuned, and it’s less than
1/10 the price of an acoustic piano of decent
quality, then the answer is yes (if you buy a
Yamaha P-515 or above). If “good” to you means
a beautiful piece of furniture, that is real
and unique and handmade, that produces its
sound by a piece of wood vibrating in response
to string vibrations, that is organic and
mechanical and clunky and wonderful, and has
the intrinsic musicality unique to real
pianos, then the answer is no.
I have
one of each, they are both wonderful
instruments, and I love them both. When I want
to emote and have a sensory experience, I go
to my baby grand. When I want to grin from ear
to ear, I go to my digital.
Q: Do
digital pianos hold their value?
A:
No. They drop in value as fast as computers
do. That's because they are
computers. They lose value is because
they become obsolete quickly, as newer ones
come out in just a few years that are so much
better. And also because they tend to
not "hold up" as well as acoustic pianos over
time. Just like computers, the
electronics and the mechanical controllers
(keys) eventually start to die.
Plan on a
digital piano being worth half of what you
paid for it a couple of years after you buy
it. And plan on replacing it every ten years
or so. Treat it in your mind more like a
car that you will need to replace after
100,000 or 200,000 miles. The good thing
is, digitals are so much cheaper than
acoustics that you can replace them many times
before spending as much as you would on an
acoustic piano. You will never have to
pay to have them tuned, and you will never
have to pay to have them moved.
