When looking into effects list of multieffect pedals (ex: Boss Gt6, Zoom ms50g...), the manual clearly identifies the effects of whom the original pedals where modeled from. And recent multieffect pedals with there modern audio processors are able to highly imitate the original effects(amps, drive, reverb, delay).
Do these companies pay royalties to the original manufacturers when they include copied sounds from them? If I buy multieffects due to their practicality in size and cost, am I supporting the original pedal/amp makers who have been manufacturing for years and deserve credit for the signature sound they made?
