High-performance preamp for electric acoustic guitars, with an equalizer for sound quality adjustment. - Model Name: EAP-2000 - Function: Electric acoustic guitar preamp - Input Type: Passive/Active - Equalizer: 100Hz, 220Hz, 500Hz, 1000Hz - Phase: Phase switch - Output Level Adjustment: Output level, Effect level Independent for piezo and magnetic pickups, blending is also possible. The sound quality is good compared to recent models, and it can also be used as a DI. It also has an effect loop (send/return). I used to put a TC reverb in it. Basic operation has been confirmed for XLR output, phone output, headphones, etc. from each input.
