Does anyone know what guitar synthesizer Mana and Közi used during the Tetsu? I'm positive that it's not prerecorded since you can hear mistakes in the playing of it (e.g. Sadness at the 新宿LOFT 『第四夜 悲劇の晩餐 Vol.4』 show). I also don't see any MIDI guitar pickups on their early instruments (like Mana's Bill Lawrence guitar), so I'm very curious as to what they used. If anyone has any ideas, please let me know! Thank you!
