​The Strymon AA.1 is a compact 4HP Eurorack module designed to seamlessly integrate guitar pedals and instruments with modular synthesizer systems. It functions as a bidirectional level shifter, attenuating hot Eurorack signals by -18dB to match guitar-level inputs and amplifying incoming instrument-level signals by +18dB to suit modular levels. This dual functionality facilitates clean signal routing between modular gear, guitar pedals, and audio interfaces without overloading or signal degradation. Its straightforward design and stereo I/O make it an efficient solution for hybrid setups.​
