I got serial #001 from Jon Cusack on Friday for a test drive. I have played with it and had tons of fun. As I was getting ready to write this review I found one that was done by Nate of Bumbox for the ToneFactor Forum. For those of you who are signed up to that board, here's the link http://p208.ezboard.com/ftonefactor...picID=807.topic For those who aren't I will copy the whole thing in the next post. Of key interest are the sound clips and a big ass video clip. Since Nate lists all the function descriptions in his review, I'll just report on my impressions. I already have the Tap-a-Whirl, so I'm familiar with the high quality of Jon's work and the way his tap tempo/speed ramping works - smooooth. The Phaser adds an extra 7 waveforms (total = 15!!), as well as a Feedback (positive and negative resonance) and Color (center frequency of the phase cycle) controls. He has also incorporated a preset system, whereby you can assign a rate, ramping speed, and tap tempo ratio to each waveform. I believe he is also offering this as a mod to existing Tap-a-Whirls and I'm definitely getting it. This is a big deal breakthrough, ladies and gentlemen. Presets for an analog pedal!! This is also a form of multieffect pedal because you get three distinct flavors - Normal Phaser, Feedback Phaser, and Vibe. The Vibe sounds closer to a vibrato than a univibe to me and works best with the simpler waveforms. The Normal phaser is a relatively sane tone. The Feedback Phaser can be totally ****ing nuts. The Feedback and Color controls are interactive and can give sounds that are very vowel like to autowah stuff to very synthy sounds. Also think mad scientist resonant filter sweeps. Since you can set or change the tempo with one or two taps of the footswitch, you can get some effects that are very envelope-like. Add in the more rhythmic waveforms and I was reminded of Adrenalinn sounds, but analog in quality and easier to tweak and fine tune. And syncable to Tap Tempo. This is not a simple pedal. There are 15 waveforms, three different effect flavors, Color and Depth variations. The Feedback only works when you are in Feedback Phaser mode. Then add in the Tap Divide - multiply or divide the rate you tap in by eight different factors. Tap in four beats to the bar and get 1/4, 1/3, 1/2, 1, 2, 3, 4, or 6 times that as the cycling rate of the phasing. Talk about your polyrhythms! It's an ugly little sucker. Diecast aluminum casing with the lettering machined into it and a rough acid washed finish. Jon also offers a black finish and I think he's planning on adding more colors. About the size of a Barber pedal, but sideways - 4 1/2" x 3 1/2" x 1 3/8". The footswitches are part of Jon's own True Bypass switching system using relays and a soft touch - no pops. How does it sound? I was reminded of my old Infinitphase at times and of my Moog. It can also be subtle, adding just a little shimmer or a slowly evolving tone shift. Like other pedals with a high feature count, there are some options where one or another of the controls have very little effect or a narrower range. The Color knob has a very noticeable effect throughout its full sweep in Feedback Phaser mode, but less so in Vibe mode. I'm not sure if I can get every phaser tone I've ever heard out of the Tap-a-Phase, but I can get a lot of them and some of them are totally unique to this puppy. Let's put it this way - one of my tests of any new pedal is whether my foot falls asleep when I first try it out. You know, when you sit or squat down on the floor next to the pedal and keep leaning over to tweak it and forget you're cutting off the blood to your leg? It happened three times! I tried some old riffs and got new sounds out of them. Hours well spent. Some hesitations - I had the Depth from 3/4 to full. Less than that and the effect really disappeared, especially in standard phaser mode. I'm gonna open it up and fiddle with the mix trimmer to see what that does. There was no Volume drop when I engaged the pedal and absolutely no Tone Suck. If the Color control is set to one extreme or the other, there is an EQ change, but set at noon, I was amazed how my tone stayed exactly the same as I turned the pedal on and off. I would like a list describing each waveform, but I'm sure that's coming. The Vibe mode is not going to replace my Voodoo Vibe, but I found some other very swampy, throbby sounds in this box in all three modes. About complexity - I have owned several very complex phasers - the Infinitphase and the ModMax. Both of those had a seemingly infinite range of tones. That's cool, but eventually overwhelming. I would find wonderfully inspiring sounds and then turn one knob and the sound would be lost, almost impossible to find again. The Tap-a-Phase is better organized. Yes there are 15 waveforms, but once you pick a waveform, there are really only a few controls to tweak - mode (vibe, phase, phase/feedback), speed, depth, color, and feedback. And feedback only works in one of the modes anyway. The Tap Divide and Brake/Ramp Speed are going to be set it once and forget it choices. Jon Cusack is making some very cool pedals. He seems to have hit that magic place of adding features that make sense, are musical, and are useable. The Tap-a-Phase sounds great, is dead quiet, runs on a 9V battery or standard Boss jack power supply, is small, and does things that no other pedal can do.
