Default Amplifier for violin

I am planning to make a violin amplifier using few components [maybe an integrated circuit]. Is there anybody in this forum who knows how to make violin amplifier? Is there a circuit where I can follow to make one?

Hi,

Electric or acoustic violin ? Basically you want an acoustic (guitar) amplifier
with emphasis towards the midrange rather than any attempt at bass.

(In a band, usually violin goes the same way as the vocals.)

Look at Cheap Acoustic Amps - Highly Rated Budget Acoustic Guitar Amps

Adding useful features to an amplifier complicates it very quickly.

Hi sreten,

Thank you for the link, I just found perfect violin amplifier for my acoustic violin.

Just be aware that a piezo violin pickup would prefer a different impedance/contoured input from what an electric guitar pickup wants.

You should realize the the curcuit useing the tlo71 is only a preamp not an amplifier so it won't drive a speaker.

Ah yes sir... that's for preamp only. Could you please recommend a good amplifier circuit that I can make [maybe a few components only using a single IC amplifier] for acoustic violin? Maybe less than 100watts will do.

I have commercially made violin-specific amps.
Use a flat preamp with 1M to 3M3 input impedance for good response with your piezo pickup and an LM3886 chipamp for very clean 60w and 2 Jensen MOD 1050 speakers.
I suggest those because they are good, inexpensive, and the frequency response is smoother than typical guitar speakers, will fit your violin without shrillness.
This is for an amp which will let you and a band hear the violin onstage, or in a small club, also send a preamp line out to the PA system.

Good advice all around, especially the bit about speakers. Violins certainly don't need the upper mid (treble) boost that guitar speakers have. I'd also recommend the Beyma 6MI90. Pricier, but a very sweet top end. (Also smaller, so it may take a few to match the output of a guitar amp on stage. )

Hi,

My jaded advice would be, buy a nice old not too powerful simple valve
guitar amplifier and replace the old guitar speaker with a smooth very
high efficiency driver originally intended for PA midrange, 10" or 12".

If you go this route you won't regret it, it will slaughter most options.

rgds, sreten.

For a good old used choice, the guitar speaker should be worth a bit.

from what I have read quite a bit higher input impedance, maybe 4M ohm ?

try a search for very high-Z input

or you can study the specs on some of new designed combos or small preamps made especially for acoustic instruments

but be aware that ordinary microphone works with much lower impedance
not sure its right, but could maybe be 2kohm, and completely different thing
I might be corrected on this
