I currently have a VHT valvulator on my pedalboard that does a great job. It makes a lot of my pedals usable; before they just sucked all the high-end out of the signal. The VHT works well with everything Ive tried except my fuzz, dirt, and wah pedal, so I put them before the buffer. The only problem I have with the VHT is the amount of real-estate it takes up on my pedalboard. I just got a gator gigbox and the lid has trouble closing with the Valvulator on the board. (Maybe I should return the gigbox and look into a different pedal board). Does anyone have any experience with the axess buffer? It looks to be much smaller than the VHT. Has anyone done any head to head comparisons?
