ok dude, here’s your problem, the memory boy and deluxe memory boy are wire up so that the blend knob when turned all the way totally eliminates the dry signal, and when its all the way down, eliminated the whole wet signal, different from other delays, just keep it somewhere in the middle

and also the beeping is cause you have the depth on the way on square wave form which is not your typical delay, keep that at 12 for standard delay, and for a tad of NORMAL modulation turn it a bit to the left, if you want it wacky anywhere over half on either side
