I like delay, a lot, and when a like something a lot I generally get all obsessed with it and need to know everything about it – how it works, what the options are, how much they cost, etc. And so here we are!
Analog vs. digital:
In the audio world many seem to think that analog is better than digital. In some cases it may very well be, but in many it’s just “different”. I think delay is one of those cases. Some of the key differences between digital and analog delays:
- Delay time: analog delays cannot achieve the same delay times as digital. Typical delay time for an analog pedal is around 500-600ms
- Looping: to my knowledge there’s no such thing in analog pedals (tape delay is whole other world though)
- Reverse delay: ditto
- Tap tempo: a very useful feature, but rarely one you’ll find in an analog delay (and when you do, expect to pay a premium, i.e. Diamond Memory Lane 2 @ about $550)
- Tone: with digital what you hear is what you get. With analog the delay is much more “coloured” – each repeat comes back a little “warmer” (less highs/more lows) and with less definition.
- Cost: expect to pay more for an analog delay, and expect the price to increase alongside the delay time.
- Tone/filter control: very useful for making your delay warmer or brighter (boosting highs and/or cutting lows). In a digital pedal this will allow you to achieve a more analog-sounding delay.
- Reverb: I’ve only seen this in one (digital) pedal (EHX Stereo Memory Man with Hazarai). It’s pretty handy for making the delays spacier and transparent. It also allows you to achieve some basic reverbs by rolling back the repeats and delay time.
- Modulation: that is, modulating the pitch of the delays to get a haunting chorus-like effect.
- Multi-tap: this can have different meanings. In some cases it means multiple delay times (i.e. one delay at 300ms, and one at 600ms), in others it means “repeat exactly X times”.
- Expression pedal: some pedals will allow you to control certain parameters via an expression pedal. This can be handy if you like to play with feedback but don’t want to break your back in the process.
- Stereo: usually stereo outs equates to ping-pong delays (repeats alternating back and forth between left and right), but in some cases you may have more control over it. Unless you have two amps or plug directly into a PA, this is really only useful for recording.
- Self-oscillation: this is when the feedbacks build up and start to resonate, resulting in a wacky “spaceship” sound. You’ll hear this in some digital pedals, but it’s inherent in analog.
If you’re wondering, I personally own the EHX Stereo Memory Man with Hazarai. It’s a great pedal that can get some fairly warm and transparent delays via the filter and reverb knobs. My second pick would be the Diamond Memory Lane 2, but I don’t have $550 to drop on a delay. In a perfect world I would own both 🙂
If you’re on a budget and want a decent analog delay check out the MXR Carbon Copy. No tap tempo, but it does offer modulation (you’ll need to open it up to change the speed and depth though). For a good basic digital delay you can’t go wrong with the Boss DD pedals (they’re up to the DD-7 now).
I hope these points give you something to think about next time you’re in the market for a new delay pedal. Happy shopping!
