I kept BogKnob between my monitors and my RME Fireface KVK V4 for 2 years, peripherals made me proud record of service. It allowed me to have a vritable CONTRL on my speakers and plug in my headphones. It is really Designed and trs strong. I think that it is difficult to design dpenser much money for so little functionality and yet is really missing the product in any home studio. Aside from the price that I be a bit excessive ... it's a great buy Too bad the circuit is not completely passive, it does not of numrique. It is these gaps that made me sell it to move to the PreSonus Central Station.
