Ah, I see sorry I didn't know what apps(s) and platform you were running. That still sounds like a latency setting, I know you mention "reverb" or you are hearing the direct sound followed by the "processed" sound (after it runs through the app(s) regardless if there are FX added).
Speaking of "lack of parts and technical support", have you reached out to IK Support? This forum is a user-to-user discussion forum, so if you are seeking official tech support from IK that would be handled via
http://www.ikmultimedia.com/contact-support and we definitely do have access to technical support for all our products. They would also be able to handle warranty issues, as we provide a solid warranty for our products though we do not sell every part separately for user servicing. We do have spare parts/cables at
https://www.ikmultimedia.com/spareparts/I'm sure the team could get you sorted out officially via the support system. Thanks!
