I'm considering selling my MXR M82 and Aguilar Octamizer to fund a C4 (or Spectrum), but only if it can do Envelope filter and Octaver as well as them (and them combined), 'nearly as good' would just annoy me because they are 90% of what I'd use the pedal for.
A couple of things are putting me off: I got an Aftershock but found it didn't quite do OD and Fuzz as well as my separate OD and Fuzz pedals, is it the same for the C4 with Octaver and Enveloped filters? Digital Octavers I've tried haven't sounded quite as good as analogue ones, I assume the same might be the same for envelope filters. Also, I guess there is loss of some of the on-hand controls that you have with two separate pedals each with individual foot switches (but could buy additional switches). So has anyone done the comparison and found the C4 to do Octaver and Enveloped filters just as well as having two separate analogue pedals? Done the exchange with no regrets?!
When I bought my C4, it kicked off my long term MXR BOD and BEF off my board. My BEF went a few months before in anticipation, but that's another story. So, answers:
1) Can the C4 replace / nail an analogue sounding octaver? Yes...totally.
2) Can the C4 replace / nail an analogue sounding filter? Yes totally and model a lot of types of filters...in fact this is probably the most featured filter pedal ever.
3) Can the C4 model both at the same time. Absolutely, it has 4 parallel voices. However, My fav OC-2 patch sounds best just as an octaver. The best sounding filters generally sound best when they are just filters and not a bundle.
4) You can't expect a 4 knob format to cover dual octave and filter functions as well as separate units. However, you can assign 3 further functions to external controls / expression pedals via midi (and a hub).
5) Will I want to use this just as an octaver & filter? No...within a hour of using this pedal and downloading patches, you will find that the synth and FM synth capabilities of this pedal far exceed your initial brief.
You get 6 patches on the front of the unit. I started with a variety of octaves and filters. My current selection is:
1) OC2 (with a fuzz on control 2, Dry / wet control 3 and expression dials in a punchy swell on the wet).
2) Pad patch
3) Usually a Blade Runner patch...however this week it's slotted up with Quatschmacher's fantastic Double Bass patch (seriously good).
4) A sweet 80's chopper patch
5) Fat synth that is also a killer filter (using the expression pedal).
6) a sequenced patch that is basically Donna Summers "I feel love" on a bass...patch.
So out of these patches...I have one octaver and a sort of filter...but mostly 5 synths.
One you have a C4 then you will find your need and want from it will grow in proportion to your ability to try out new sounds / things with it. You might prefer an Intelligent Filter instead. Or both!
