I like them both. The Night wire is a harmonic tremolo, so it is a bit different to the normal square wave sound. You can set the rate so it responds to the pick dynamics, the harder you pick the faster it goes. You can do the same with the frequency knob, which controls the high and low pass filters are set. This means you can get a sort of autowah effect if you want to. It’s a real clever pedal. The D&M drive is two great sounding overdrives in one package.
