Welcome to the show! Today we’re comparing two effects that can easily be confused for one another: vibe and harmonic tremolo.
Vibe is derived from the ‘Uni-Vibe’ of 1968, and it’s the classic churning, pulsing, four-stage phaser created using a bulb and light dependent resistors. Robin Trower, Jimi Hendrix, Trey Anastasio, Gilmour… you know it when you hear it!
Harmonic tremolo came about almost a decade earlier in a handful of Fender guitar amplifiers.You take two tremolo circuits, make one deal with higher frequencies, one deal with lower frequencies and put them out of phase. There’s no pitch shifting going on (as there is in the Magnatone vibrato for example). It’s a mesmeric sound that doesn’t have the gut-wrenching churn of vibe.
We are using two of our favourite modern recreations of each effect for today’s examples. Clearly there are many, many others to choose from and no doubt you all have your favourites: these are ours.
After explaining and comparing the effects themselves we move on to discussing some related tone questions, chiefly the order in which you might want to use overdrive and fuzz, which is always the subject of much debate.
Enjoy the show!
