Subdecay Quasar Dlx Review

tigerbass was kind enough to loan me his and it arrived yesterday and I've been fiddling with it since.

More or less these are just some random thoughts that I'll add too and hopefully record and post some clips before I return it.

Anyone who has played a Quasar or especially the Baby Quasar knows what is at the heart of this feature packed beast. All of the qualities that make it's predecessors great phasers are still there. Leaving the Quasar Dlx in 4 stage mode, not using any of the more unusual waveforms (just sine and triangle), expression control, tap tempo or the ridiculously fast speeds that give ring mod-like tones and you get the feel for its ability as a more standard phaser.

And it is very much like I remembered it. The frequency control is a fantastic control that I wish more phasers had. The depth knob has a very wide range. It is more present and lush sounding at half depth than most phasers are all the way up.

The voice mode controls the positive and negative feedback. Dead center is useful for avoiding artifacts in the modes incorporating square waves. A bit on either side gives vibrato like sounds and all the way up gives very prominent pulses without getting into self-oscillation territory which is nice. Personally I like positive feedback much more on bass and the sweetspot for me is between 1 and 3 o'clock depending on other controls.

Mix knob is a clean blend that goes all the way wet if desired.

If I had a quibble about the basic phase tones it would be that there aren't a couple more interesting "basic" phaser waveshapes (assymetric, sawtooth up and/or down etc) but other than that it sounds great. Anyone who digs the Maxon PH-350 you can nail those tones with the waveform on triangle, frequency at 2 o'clock or so, the mix at 50, the depth around half to 3/4 and the voice and speed to taste. Obviously this one goes 4/6/8 stages to the Maxon's 4/6/10 but other than that it can ape the Maxon perfectly.

I'm a huge 6 stage phaser fan and this one sounds great. And the 8 stage gets into more electronica sounding phasing.

Tap tempo and manual speed modes work great and the "double back" feature on speed knob allows for ultra fast, clangy ring mod like sounds. Expression control is fun, especially of rate. Sweeping the phase manually is fun but I don't really have a use for it.

The more unique waveforms sound good but as always I think unless playing double stops or chords with room in the mix they will get lost in the mix on bass when playing clean. Also, the square wave modes will introduce more artifacts as the voice knob is turned from dead center.

Where I find the additional waveforms most useful on bass is when using a fuzz in front of the Quasar, especially a gated one. This easily gets the pedal into pseudo MuRF or Pitchfactor territory. I especially dig the random step mode. With fuzz it's everything I loved about the original Robotalk without the need for a blend pedal and volume boost.

It can be powered by 18V to increase headroom.

The LFO noise is louder than expected and being so feature laden I could see people having a steep learning curve or struggling to find or recall settings they like but other than that this really is the most amazing phaser I've ever tried.
 
Thanks!

Is there a significant volume difference (averaged overall output volume) with the pedal on? Naturally, you expect a little dip & swell at some settings, but is there an obvious gain shift?

You're right - phasers are a bit like tremolo in that if the peaks are still at unity there's an apparent volume drop because the troughs are quieter and the average volume reduced. And higher resonances make the peaks louder so really finding "unity" gain with phasers that have a knob or trimmer for volume can be difficult.

With more stages this is even more apparent.

To my ears the Subdecay certainly doesn't have a volume drop. Depending on the depth, voice and mix settings it can be a slight boost, which I like.
 
I've spent most of the afternoon trying to cop different phaser tones out of the Quasar Dlx. Some I've got to try head to head, other's I'm working from memory.

But so far I've been able to coax very close representations of my favorite settings on the Small Stone, Keeley, Pigtronix EP-1 (Univibe type tones in general) and Mutron Phasor II.

Surprisingly I had trouble copping a script circuit/Phase 90 sound in my first attempt but I'll try again later.

In short, the Quasar Dlx brings all the super weird sounds that it promises, but it can also do a range of normal phase tones.

One disappointment is that I haven't been able to use the basic square wave mode. The thumps between successive square waves are just too loud.
 
MAN! that pedals sounds way too good BUT why would anyone build a pedal that has almost an infinite number of possible sounds and not put presets? :mad:

I remember him saying something about wanting the pedal to stay as analog, as as cheap as possible. Presets = Digital = More cost.

But if you do find two settings you like, just buy another one.:D

Cheers for the review.
 
That's pretty much what I was thinking regarding presets. Added complexity equals added cost. Plus added size for sure considering how much is already stuffed in that small enclosure.

And I love envelope phasing too but that takes more circuitry than adding another waveform.

This is seriously the most we'll thought out and feature packed phaser I've ever seen and it runs off standard 9V (or an optional 18V) and is super compact. As pedal junkies it's our nature to always want more but what Subdecay has done here really is amazing.
 
I don't mind forking over more $ for presets..as I would imagine others wouldn't either.

Something I hadn't even really considered is that Subdecay may not be able to do presets. AFAIK none of their other pedals have them and from the little bit I've read about the making of the Quasar Dlx it sounds like this was the first pedal where they did any significant programming.

And just to update what I wrote earlier, I was able to coax a very convincing Phase 90 tone. One thing that can't be overstated is how much range there is on the depth knob. I rarely put it past noon unless I'm really emphasizing the pulses in one of the stepped waveforms. To get Phase 90 sounds I actually had to dial it back to almost the minimum.

With so much range of control (4/6/8 stages, lots of positive and negative feedback, wet/dry mix, huge range of depth/resonance and especially the frequency control) this phaser is an absolute chameleon and can ape pretty much any phaser tone.
 
Ordering one this week. i'll be sure to do some nice soundclips

That was pretty much my only regret was not having the time to sit down and really do soundclips.

That said, this phaser is INCREDIBLY deep. Even without all the wackier and fun waveforms you can get a staggering array of "normal" phase tones. It really is a chameleon in that respect.
 
If you say it's the best phaser you've owned, it's more than I need to confirm the awesome. Since you are mr. phaser here.

This and the Malekko 919 have been on my very small GAS list for the past 2 years...

I don't know if I should eventually get this or the Empress Phaser when I begin putting my modulation/noise board in the future. Both pedals look so promising...

I can't decide either! The Subdecay seems to have 'more' sounds, but the Empress sound quality is hard to beat!
