I was reorganizing my pedal board and I needed some extra power outlets for 3 other pedals, since my Pedal Power 2 only has 8. I checked other power boxes, but they all had 7-8 and cost the same or more than the PP2, and I was trying to avoid buying another PP2. Then I stumbled on to the VHT Valvulator 1, which is really a tube buffer first, and a pedal power outlet secondarily. As I read more about it, as well as reading the reviews, I became intrigued. I've already got an Axess BS2, which performs its job quite well, so I didn't really 'need' a buffer, but the extra pedal power outlets (4) and the 'tube' component got my attention. So I bought one used from a GP member and it arrived today. At first, it was noisy, and I was concerned, but flipping the Ground Lift switch took care of that - dead quiet. The tone was nice, but a bit harsh, so I swapped out the 2 year old Sovtek tube (12AX7) for a Telefunken, and WOW! That did it! :AOK What beautiful sweet tones. Then I tried a NOS JAN GE 12AX7WA (excellent, inexpensive NOS tube BTW), and that was also terrific. Slightly different from the Telefunken, but excellent in its own right. They were both really nice, but I decided to leave the JAN GE in for now. I can always swap it out later if I feel like a change - very cool! The Valvulator 1 buffers as well as the BS2, but the 'tube mojo' puts it over the top. My pedals sounded better - more upper end detail and tighter lower end, and the 'feel/articulation' was noticably improved all round - pedals or not. I am very impressed. Plus, I have 4 isolated outlets for pedals, including a 12v outlet (#1), which I plan to use for my new Zendrive2, whenever it arrives. I can't wait to try different tubes in the Zendrive2. Anyone looking for a buffer for their pedal board should definitely check out a VHT Valvulator 1, and don't forget to put in a nice tube. Highly recommended.
