Title: More phasery sound from a smoothie
Post by: jimilee on December 30, 2012, 12:01:34 AM
So i just finished a smoothie, but to me it sounds more vibrato than phaser. I didn't use a reverse audio pot, just a normal audio pot., I'm still waiting on one to get here in Monday hopefully. With this make a difference at all or is there a way to get a more phasery sound out of it?

I'm not sure how the normal pot affects the smoothie, but overall, it is a pretty subtle phaser. I love this thing when I'm playing stuff like lynard skynrd, but it is not suitable for EHV, etc. If that's what your looking for I would build a phase 90 or something similar...

Did you closely match the FETs? 
Have you set the bias trimmer correctly?
These are the two most obvious reasons for poor phase  shifting

Assuming you do have matched transistors and everything is working properly, you may just be looking for a deeper phase sound like the Phase 90. The Smoothie is pretty rich but it is not necessarily "intense". I would check out some Phase 45 videos on youTube and compare your results.

Yep, ordered a matched set from gpcb and I believe I have it trimmed correctly, I played with it for a while. Near as I can tell a reverse audio and an audio pot do the same thing, except in reverse. The audio makes changes in the last little bit as a reverse does things in the first say 2/3 of the pot

Thanks Brian, I did find a video here in the forum with the same results, I think you're right a phase 90 maybe what I'm after, don't know where I can an get a pcb for that do you?  ;D

Sounds great with my guitar,not so much with my bass,I think the Nautilus is more what I am after than the phase 90. Has anyone or can you use 18 volts on it to increase the sweep?  :P

I'm pretty sure Tonepad still carries one. Probably guitarpcb, too. I would not mind doing a PCB for it, either, but I haven't put any time into it.

I got my phase 90 board from tonepad and it is great! It will take about 2 weeks or so for shipping as it is out of the states...

I've built an etched 90 from the Tonepad layout. Needs jumpers, but it'll do.

Consider building a Ross.

A Ross over a nautilus? I'm in, does tonepad have those?

Yep! It is a little spendy though. If you build one I'd love to hear your opinion. I might just have to give it a try. ;D  Here is a link to ordering page at tonepad:

Wow that is a bit spend, the sound samples sound really good too. I'm looking for something a little more over the top for bass, almost like an old touch wah from 20 years ago. I heard a boss phaser I really liked, but I'm done buying commercial pedals I think.

I would buy one or two...

More stages = more notchy goodness, think the Tonepad ROSS has pads to add more stages (build one on perf or vero).

Phasers sound better with a good signal to work with, may be the bass just doesn't have the harmonics with that fewer stages, try it fuzzed out. Regen/Feedback like the Ross'll probably help you though.

Personally i'd wait for Bean to finish up the Stage Fright. That or try playing with the Dry/Wet mix resistors to get a more pleasing sound but it wont really deepen the phase, just make it more or less obvious.

The tonepad Ross phaser KILLS the phase 90 if you ask this phaser junkie. Really the extra stages for the Ross are not necessary IMO as it is a great phaser with 4 stages. I beleive he calls it the Ropez. There are also a ton of great mods for the project. I added a "depth" control to mine which changes the sweep width for even more options.

madbeans stage fright sounds very promising as well if you want to hold out.

Stagefright? I'm all ears now. I'm building a bear hug and a paramix with a multiplex waiting on deck and a Jazz bass waiting in the wings,so I have time before I'm back round to a phaser again. Anything Brian has going on will definitely be worth the wait.

highly recomend a breadboard rig. with this you can build the whole damn project without a lick of solder. dont like the sound, swap out parts, drink a beer and try something else. once you like something ..... pull out the iron. This is how mods get going. cant make up your mind and want it all ? ? ?

spark any ideas?
haw about different matched pairs with a switch for each pair (just for starters)

I find mxr phasers respond best to thin single coil signal.  Vintage strength humbuckers sound good too, ala VH, but high output HB's make them sound a lot less swooshy.  I can imagine the bass makes it even more subdued.

Post by: jimilee on January 01, 2013, 07:27:57 PM
Yeah it does. When I play in the upper registers I get more effect, but you're absolutely right. Looking at a nautilus ti really screw things up. I use effects on my bass to mostly amuse myself really.

You could experiment with an eq in front if the smoothie.

Or an octave pedal in conjuction with the Paramix I'm building,that'd be cool
