Best cheap audio interface / sound card for amp simulators

Best cheap audio interface / sound card for amp simulators

Many home recordists and especially guitar players friends asked me whats the best bang for the buck audio interface, which will not  cost us an arm and a leg!  🙂

I’m going to recommend a few interfaces, which are  Amp Simulation Plugins friendly and will give you acceptable results with a little effort !

I think we are living in an amazing times! I wish I had these 14 years ago, when I paid a bag with money for a Cream Ware Luna  card. The inputs of that card were just Line in ones and I had to get a pre amp and a DI Box at additional expenses…

The audio interface is  the first thing you’re going to need, to build your small studio setup around and using it with amp sims!

So, here are a few USB audio interfaces to choose from with good features and at the same time for a price of a guitar pedal.
Playing and recording at home couldn’t be much easier today.

A few facts first:

They are small and easy to care and at the same time they are capable to get the job done!
You can use them with your Laptop on the road!

All of them have guitar/instrument input, microphone input and low latency drivers.

3. Powering
All of them are bus powered / USB port – powered/

4. Advantages
Enough options to start a small bedroom studio. Recording one instrument and a microphone.


  • Microphone  -input with  pre amplifier for using Microphone with or without phantom Power (+48v) to a studio condenser microphone via an XLR socket
  • Instrument  input – TS/TRS cable for guitar and other line signal sources . HI-Z input.
    I prefer Hi-Z instrument input with 1 MΩ impedance!
    In my experience this gives the best clarity and sound when using amp simulation software
  • MIDI – connecting midi keyboards , drum machines etc –


  • Headphones – monitoring the audio with Headphones
  • Monitors – outputs on back for Studio Monitors
  • USB Interface Cable  – connection to your computer

Low latency drivers.
Depends on your CPU power.  Really low latencies will increase CPU usage. You may experience audio artifacts “crackles” “pop’s”

But any of current modern CPU processors should be able to handle the audio stream.

I’m using i3 and i5 processors at the moment from the “third generation” of Intel Processors and they are powerful enough!

Important tips for better performance and low latency  using a Laptop!

Make sure you use USB 2.0 port!

Go to general power management of your computer:
Start > Control Panel > System and Security > Power Options.
Power Scheme to High Performance

Power Options :

Change advanced power settings:
Hard disc > Turn off hard disk after > Setting (Minutes) = Never
Sleep > Sleep after > Setting (Minutes) = Never
USB settings > USB selective suspend setting > Setting = Disabled

Processor power management > Minimum processor state > Setting = 100%
Processor power management > Maximum processor state > Setting = 100%

Behringer U-Phoria UMC204HD price: $79.99 – NO ASIO! Works with ASIO4ALL


For the price it has an amazing list of
options. The input pads are here! If you use hot active pickups, this is a life saver!
Some of the other brands doesn’t include this functionality to lower hot levels.
Great pre amps , up to 192kHz

Some users report the DI inputs do not sounds good.  But that’s subjective…
It depends on your guitar and pickups!

Presonus AudioBox (USB connection) price: $99


Affordable, stable recording interface

New interface from Steinberg with promising specs at amazing price!

Hi-Z instrument input with 1 MΩ impedance!
Legendary D-PRE  microphone preamp from Yamaha.

UR12’s gain needs to be adjusted up to 80% to get a good input without clipping! This could rise the noise floor!

It doesn’t have an independent knob for output and headset, which is troublesome.

Steinberg UR12 USB Features:

Two input, two output USB 2.0 class compliant audio interface
Single D-PRE microphone preamp
Up to 192 kHz sampling rates and 24-bit resolution
Latency-free hardware monitoring with an easy-to-use monitor source switch
