Hello. I need to buy a amplifier that gives good sound. Atm im using one amp thats for guitars I guess, so the sound of it its completly different of the real sound if im using headphones. I play in my nord an my father in guitar. My question is, whats better, an amplifier only for my keyboard, or for both? ( keyboard and guitar )? If its only for keyboard, witch one do u recommend to use only in home? or for both? I Dont want high prices, mostly 200€
