Strymon AA-1 is an interface module for modules Synthesizer in Eurorack format. The AA1 is designed to amplify guitar signals to modular levels. This allows electric guitars to be edited with filters, waveshapers and effects from the Modular Synthesizer . Incoming audio material is internally amplified by +18 dB and provided at two 3.5 mm jack outputs. In addition, two modular signals can be introduced into the module, where they are attenuated by -18 dB. The results are then brought back to guitar level and distributed to two 6.3 mm jack sockets.
