The Guyatone PS-109 Analog Delay is another great example of a MN3005 BBD delay pedal. As made famous by the Maxon AD-900 and early Boss DM-2's, the MN3005 is a long discontinued chip that is one of the most desirable BBD chips ever made. The PS-109 is an 18v circuit that includes both options for line and mic input impedance. The PS-109 has a deep, dark analog echo/delay that includes an input control to control the gain of the input signal, allowing for compensation for single coil and higher output pickups.
