Acoustic Amps and their Pots

[Magnifus]

Hello everyone,
Is there a major difference in freq. range between electric guitar amps and acoustic guitar amps? If I swapped out the pots on a small electric guitar practice amp could I make it a bit more suitable for an acoustic? Any suggestions would be appreciated! Thanks!

It really depends on the pickups in your acoustic. A piezo type likes high input impedance, unless it has a built in preamp which is the same as plugging a stomp box into your amp. Changing pots wouldn't buy you anything. The pot values, for volume for instance, are a load resistor for it's previouse stage, and should be 500k-1M if it is a tube, considerably less if it is a transistor. Switching it out has no basis on being for electric or acoustic. The stomp box effects for Acoustic Guitar, and preamps for acoustic amplifiers have different EQ enhancement for an 'acoustic' sound
and input buffering.

The acoustic is mic'd, there's no pickup. Should I get an external eq?

I always figured the main difference was headroom. Distortion is generally undesirable when amplifying acoustic guitars. You say it's a small practice amp... like 5 watt-ish? Is that going to cut it?

If this is for a live situation, you may have more to deal with using a mic on an acoustic guitar. You'll be wrestling with feedback and choice of microphone to say the least. You may be farther ahead by saving your nickels and getting an acoustic pickup, but the feedback potential is still there. A small practice amp is also a compromise unless you cheat a little with external speakers. You just gotta plug stuff in and see what you like.
