What a great piece of kit! I went with this, in spite of the high cost and narrow focus, over other amp modeling pedals because in the demos I watched, it just sounded so much better to me. In person it is every bit as convincing. I can't have a tube amp in my apartment, and this thing does the trick perfectly. The spring reverb is fantastic, and even though it only models "one" amp, with the three different mod options and six cabinet/mic IRs, there's actually a decent amount of versatility to it. It has a decent amount of gain breakup on tap for pretty much anything but metal (though you can get some chugs out of it with the right settings), but I have mainly been using it clean as a pedal platform and it has taken even my most gnarly fuzz boxes like a champ.

So far I've played it running into the FX return on my Quilter Steelaire with the cab/mic IR turned off, and also direct into Sony MDR-7506 headphones using an $8 Y-splitter cable, and it sounds great both ways. I'm sure it will also sound great coming out of monitors via my mixer or audio interface, but I haven't gotten around to trying that out yet. I'll note that the headphone method is a little quieter and I have to crank the output to about 75%, so high impedance headphones might not work with it.

A couple of caveats:

1) Even though it has some tonal range, it is still a Deluxe Reverb at its core. If you don't like that signature chimey, scooped sound, this isn't going to do it for you.

2) Getting it to connect to bluetooth to get access to the configuration settings in the app was frustrating for no reason and left a bad taste in my mouth dealing with customer support. Once you connect it the first time, the app forces it to download a bunch of factory presets with no way to skip that, and it just kept disconnecting during this process, so it wouldn't allow me to actually use any of the app functions. I spent an hour trying to get it to work, before reaching out to UAFX support. The next day they asked me to try some troubleshooting steps that I had already done, and then of course, before I even did anything it suddenly was able to successfully complete the download and gave me full access to the app.

I really only wanted the app so that I could reconfigure the footswitches, which will let you toggle presets, toggle the boost/reverb/vibrato, or switch between the pedal and your preamp with the 4-cable setup. There are only two footswitches though, so you have to choose wisely. I messed around a bit with the preset switcher on the app but was still getting random bluetooth disconnects. I have no need for an app to change presets, since the settings are so easy to dial in using the knobs and switches on the pedals, and I'll most likely just use this as a "set and forget" type of pedal with minor tweaks. But if you're somebody who is playing in a cover band or something, and need that app to quickly change settings between songs, I would be wary of the unreliable bluetooth.

When I mentioned to UAFX customer support that I got my situation sorted out, but that the bluetooth connection was still spotty and they should consider allowing a way to access the app features with a USB connection, they just kind of said "Glad it's working better" and didn't mention anything about the disconnect issues or my feature suggestion. So maybe they'll address it, but I'm not holding my breath on that.

Anyway, in spite of the initial bluetooth fiasco, I am thoroughly pleased with this pedal after having it for nearly a month now. Gave me exactly what I needed: a plethora of Deluxe Reverb tones without getting me evicted for noise complaints.

Loving the new pedal. Still exploring everything that it is capable of. Tubes make all the difference driving a tremolo pedal. Thanks Steve!

Decided to give this a try after really liking their golden reverb pedal. Was really skeptical that an amp could be emulated realistically enough for my ear, but figured if anyone could do it they could. I was not disappointed!

I don't like most drive pedals, I love this one. Best drive pedal I've ever used, hands down.

This pedal has such a special sounding and harmonic richness.

Delay that Rock hard ! Bit crusher and wild modulations add amazing sounds to my synth! Shiped right away, great packaging and rare pedal ,keep being sickk guys

Originally I bought it with the intent of using it as distortion, but I ended up liking it more as a low-gain overdrive. It can also do a really awesome fuzzy sound. The blend and tone knobs give you enough versatility for the money.

feels like its own voice, somewhere between the OC-2 and the EBS octaver. the octave sound has a similar character to an OC-2 but it's fatter. plenty of output available for both octave and dry signal. tracking is really good right to the low A.

Got this pedal the other day and am still just getting a handle on all that’s happening here. The initial selling point for me was the LP/HP filter and it does not disappoint. It’s a powerful tool that really sets this thing apart from a lot of the other “lo-fi” pedals I’ve experienced. I’m particularly enjoying the low pass filter with the bit crusher. Just be prepared for a pretty huge volume jump when you engage that bit crusher. I suppose if I had one complaint thus far ,it is the fact that there are some jarring lag/volume jumps when you engage those toggle switches which might make it difficult to manipulate the pedal in real time in a recording/performance situation.
But overall, there is tons to explore here and there seems to be ample opportunity to dial in some pretty subtle one of a kind sounds with this pedal. If you are looking for a sophisticated sound shaping tool then the Wardenclyffe Delux might be the pedal for you. I have a feeling that I will be exploring its capabilities for a long time. Which I find super exciting!

I spent an hour or three playing with this after it arrived [just TWO business days after ordering] and on its own is fabulously magical. I haven’t read the manual yet but even whilst goofing around I managed to a good old-fashioned cramp in the smiling muscles. Looking forward to diving in deeper and marrying it to other processing in my rig.

Adds interesting depth to your playing, I think if you like adding phase to things like solos for some extra movement, this is an awesome augmentation to that as the randomization makes things way more interesting for both the listener and the player

not just a harmonic percolator to do albini stuff with, but also a source of your favorite '90s solid state amp metal sounds (schuldiner, etc.) and harsh early metalcore tones
one of the few rare perfect pedals

Incredible lower gain Fuzz Face that stacks fantastically with your amp and other pedals. Features the earliest example of Mullard silicon transistors. A very cool pedal!

I use it for my bass. It has just two knobs, it’s simple, and sounds incredible!! If you play in a band that leaves a little room for the bass player to take a solo every now and again, just flip this on and have a blast.

If you're looking at this pedal you probably already know about Ezhi & Aka. This pedal isn't for everyone, but it's for me and those of like minds. The people who like to communicate with spirits. Do those communications always make sense? No, but you keep speaking and you keep listening, and you keep hearing insights that can come about no other way. This one is for the adventurous curators of found sounds. Those who like to play in other worlds and get lost in abstract communications.
