Strymon AA.1 Amplifier

Eurorack amplifier/attenuator for external pedals.

• Compact bridge (4HP) between Eurorack systems and guitar/bass pedals
• Allows you to integrate instruments and pedals with your modular setup
• Solves signal level problems between Eurorack and instrument-level equipment
• Amplifies guitar-level signals and attenuates Eurorack-level signals
• Intuitive and easy-to-use design

The Strymon AA.1 Amplifier is the compact module (4HP) essential for bridging the gap between your Eurorack system and the world of guitar or bass pedals. Designed with Strymon's signature reliability and quality, the AA.1 gives you everything you need to flawlessly interface your effects pedals, guitar or bass with your modular setup.

Integrate your Guitar with the Modular: Strymon AA.1

With the AA.1, the possibilities for combining your guitar instrumentation with Eurorack modules are virtually limitless. You can connect a pedal to the send and return of modules such as Magneto, use your guitar or bass as a sound source for creative manipulations with your modular setup, or even send an instrument-level stereo master output from your modular rack to an audio interface. The AA.1 is specifically designed to facilitate all kinds of integration.

Optimized Level Management for Euroracks and Pedals

One of the biggest problems in integrating guitar-level equipment with the Eurorack world is signal level management. Most Eurorack modules produce very high audio signals, which can easily overload the inputs of effects pedals or audio interfaces. Likewise, the audio inputs of a Eurorack system require "warmer" signals. The AA.1 solves these problems by amplifying the input (guitar) signals and attenuating the output (Eurorack) signals to the appropriate levels, ensuring seamless, distortion-free sound integration.

Ease of Use for Immediate Workflow

Using the Strymon AA.1 is extremely intuitive. The 1/4" stereo input amplifies guitar-level signals by +18dB, sending the amplified signal through the 1/8" outputs (use the left output for mono). The 1/8" inputs attenuate Eurorack level signals by -18dB, routing the attenuated signal through the 1/4" outputs suitable for guitar level products. This makes integration quick and uncomplicated, allowing you to focus on your music.
