Saw one of these while looking online for a possible new preamp. Does anyone have any experience with them? How do they compare to other pre's and does anyone have any clips of them? Any feedback is much appreciated

I'm not a huge fan. Although it sounds very organic compared to other preamps, it's definitely not for metal, and the MIDI is not designed that well.
If you're looking for a cool preamp, I'd suggest an ADA MP-1.

I'm reallly digging it (sorry, don't have any clips). it's too expensive though.
get the Soldano sp-77 (and change one resistor) instead

I think he was just using the poweramp, :???:
Anyway, I had one, but it didn't really deliver the sound I was looking for. I think the UL or CL on its own sounds way better than a GP3 + 2/50/2 or 2/90/2 together, but that's just me. There's a gain mod on the VHT forum for this preamp, but I just went back to using my MP-1/VHT 2/50/2, rather than spend time trying to mod it.

I had one years ago - I may have had a bad unit, but I wasn't willing to give it another try due to the issue + their MIDI implementation. Here's part of my HC review on the unit addressing the deal breaker for me:
http://reviews.harmony-central.com/reviews/Guitar+Amp/product/VHT/Valvulator+GP3+Preamp/10/1
I've read the GP-3 contains a thermal sensor to shut it down if/when it overheats...then there's the case completely enclosing all the tubes. I didn't see a fan on my unit either and the ventilation looked poor. I kept my GP-3 in a very well ventilated rack. For the first few days of owning this, I used it maybe 30-40 minutes at a time and would shut it down. Around day 5 I left it on while surfing the web after playing for maybe 20-30 minutes. Somewhere around 1.5 hours into the unit being on I was startled by a sudden high-midrange hum...not a pleasant hum either - very irritating. The volume on my guitar was off, btw...it wasn't feedback. The GP-3 was so hot I couldn't touch it for longer than a second...it was so hot it could/would have easily have given me blisters from the heat. I tried pushing buttons, turning knobs, and messing with the 6-band EQ, but nothing made the hum disappear. Moving the lowest frequency slider on the 6-band EQ did cause the hum to change pitch slightly. Turning the unit off, then on did not make the hum disappear....it only functioned normally when I kept if off for several hours - long enough to cool off.
Unfortunately, the scenario with the irritating hum occurred two more times as I guessed it had something to do with leaving the unit on for more than an hour...the hum happened without fail. Also, this hum is the ONLY thing I was able to hear when this was happening - I tried playing my guitar while the hum was occurring, but heard NO guitar at all...nothing but hum.
