Feature:
Maybe I'm small minded when it comes to effects, but I can't find anything that it is lacking. I find plenty of things to monkey around with when reaching for a sound. I there is more than one way to acheive the general sound I'm after giving me the choice of setting that best suits my taste and play style. Comes with a power cord, which is always nice. I find the loop feature next to useless, but that's just me. I loose nothing by it being available. Tuner is great, but I can't seem to get the muted tuner mode from the large switches. I have to use the small button to activate that mode and while certainly not the end of the world, it is an agravating flaw.

Quality:
Seems to be well made. After i've wagged it around for a few years i'll let you know about the durabillity. I do have a concern about the tube. Enevitably it will need changing shortly after my warranty expires and i'll be forced to tear into the whole pedal to change it out. A trap door for easy access to the tube would have been an easy addition.

Value:
I got a warehouse resealed unit and found the savings well worth it. If it hadn't been labled as resealed I'd have been hard pressed to have known it. I've not had the chance to play simular units from other manufacturers, however, I have a real sense that the great sound from the tube accelerator would edge it out ahead of the competition in value for sound for most users.

Desirability:
Brilliant red with chrome accents and a glowing tube visible through the cooling slots. Very nice.

Sound:
It seems to be possible to pull any sound you like out of the thing. I've worked up several custom patches that suit the different styles and songs my band covers and have yet to find a desired sound that it can't match. I even worked up a good sounding emulation of the bass sound from Genuine's Pony. I love the smooth warm tone the tube adds. I use it as a direct box with an amp monitor, so the cabinet and amp emulations were of interest to me. I have found them to sound very good and noticeably effect the tone, but I can't speak to the accuracy of the emulation as I've never owned any of devices emulated. I've found the presets serve their intended function of demonstraiting some things that are possible with the pedal and displaying the features, but most players will find them useless for playing gigs without some customizeation.

Ease of Use:
I was making custom patches after about the second quick run through of the presets. I have found the controls for editing and saving patches very intuative. Programing the pedal is a little bit tricky, but you can tweek so many things about it's opperation I see no obvious way they could have made it simpler. Manual is extensive and I did skim through it while making my decision to buy. I have referenced it several times when building a desired sound and found it useful.

Support:
No experience

Overall:
I think this will complete my bass rig for at least the forseable future. Should i have to replace it, it would take some real suprises from competative units to make me switch.

Feature:
Definately a 10. Once you get the programing down, the flexability of this unit is unrivaled by anything else on the market. I am a 5 string rock bassist of 17 yrs. Some of our songs I use layers of effects that I need to be able to come in and out of on the fly, and the switch ability in play mode is invaluable to me.

Quality:
As solid of a unit as you will find. Solid steel body, nice switches, and a cast aluminum pedal seem to be very road worthy.

Value:
A bit high but you can pay more for less so do your homework before you buy. (I read the manual twice before I bought this one)

Desirability:
Very attractive unit, and almost half the size of the on that it replaced with about 50% more flexability.

Sound:
I gave the sound an 8 because some of the effects create a light hum, which is to be expected in most all lower level effects, but a top of the line piece of gear I would expect to be just a little cleaner.

Ease of Use:
Really a 10 for me, but I'm writing this review to help others, so if your not well versed in multiple programable effects this has a bit of a learning curve to it.

Support:
haven't had to use support so I can't say. We'll say 6 until I need them

Overall:
As close to a 10 as I have seen, but with my 17 yrs. exp. your really gonna have to blow my doors off to get a 10.
