Your acoustic guitars simply deserve to sound as they were meant to.

The AP1 Compact sounds exactly like our renowned AP1 Acoustic Preamp. But it has a much smaller footprint, making it even more pedalboard-friendly.

In short, we have focused on the basic features that acoustic guitar players require: An amazing-sounding preamp, Tuner Out, and transformer-balanced DI Out for your FOH engineer, who will be very happy with the signal you provide from your AP1 Compact.

The pedal is designed for low voltages and will accept 9-18VDC.

Whether you use piezo pickups or built-in microphones, AP1 Compact will make your guitar sound the way it was meant to.

The DI features the exact same preamp design and custom-made audio transformer as the AP1.


What do you get when you add an AP1 Acoustic Preamp, AP1 ACompact or ACC1 to your signal? We set out to explore via an A/B recording setup in the first video listed above.

The technical setup is designed to emulate a real live sound environment, using a custom-designed active splitter box. One signal runs through an active DI box similar to the ones you find on most stages. The other signal runs through an AP1 Compact Acoustic Preamp, and both signals are recorded directly through the line inputs of an RME audio interface.

NOTE! As always with critical listening, please do not rely on the built-in speakers on your mobile device, but use headphones or good speakers!
