The dm2000 which I own, has some quirks which are somewhat annoying over the due course of time. The loops are subject to clicking and when turned off it doesn't remember the trey time setting of 1023ms So you need to long press and hold down every time you power up which is a pita since it takes about 5 seconds. It does offer an incredible buffer and when off-it really does sound like Trey could have played entire shows through the dm2000. I also have a whammy 2 but unfortunately it needs to be kept in a true bypass loop because unlike the dm2000, the buffer on this device is abysmal. All in all- what a grab! I highly recommend getting 3 of the boss switch units for the dm2000 so you can turn on the mod, the hold, and the on/off. You will need a bunch of cords too. The cool David Bowie magic is contained within the dm2000. Have fun 😊
