Practice amp vs audio interface

This is the honest answer to the question for most people, because it refuses the premise. Positive Grid publishes a USB recording interface alongside the amp, plus Bluetooth audio, an eighth-inch aux in and a headphone output — so it is a speaker in the room when you want one, and a way into a DAW when you do not.

33 amp models and 43 effects covering noise gate, compressor, distortion, modulation, EQ, delay and reverb is a wide enough palette that you are not shopping for pedals on day one.

The cons are the speakers and the routing. Two 4-inch drivers cannot move air the way a 12-inch can — this is a desk and sofa amp, not a rehearsal-room one. There is no effects loop and no external speaker output, so it does not grow with you.

If the plan is headphones and a computer, this is the version of that plan that also works on a stage. Line 6 publishes 24-bit/96 kHz multi-channel USB audio, over 300 amps, cabs and effects from the Helix family, IR loading, stereo I/O and an effects loop.

The distinction that matters against a plain audio interface is that the sound is made in the box. A bare interface passes a clean signal to your computer and leaves the amp modeling to software you also have to buy, configure and keep running. This does it in hardware, silently, with three footswitches.

The cons: it asks for 3 A at 9 V, which no standard pedalboard brick supplies — see powering an HX Stomp. And it makes no sound in the room at all. Without headphones or monitors you have nothing.

USB audio for recording, on a 25 W combo at the bottom of the price range, is the specification that makes this relevant here. It is an amp in the room, and it is a way to get a recorded signal into a computer, and it does not require you to choose in advance.

30 user-editable presets with a color display and front-panel or USB editing is more control than a practice amp at this level usually gives you.

The cons are more or less stated by Fender's own materials. No effects loop, no Bluetooth, and the 8-inch onboard speaker is the weak link — the modeling is better than the box it comes in, which is an argument for using the headphone output most of the time.

We are not picking this one for this question, and it is a perfectly good amp — it appears on our practice amp page for the job it does do.

It has a headphone out, an aux in, built-in reverb, delay, chorus, vibratone and tremolo, and a voice selector. What it does not have is USB recording, an XLR output or an effects loop. Fender publishes all of that.

That makes it a pure practice amp, and if you are certain you will never want to record, it is a legitimate choice. If there is any chance you will, the LT25 above adds USB audio for a small step up and removes a future purchase. Best practice amps covers the category on its own terms.
