The Lovepedal Mini Valve is an upgraded version of the classic Balance Ultimate Pre Amp.. Upgrades include 9VDC filtered Power Input Jack that will accept any Negative ground power supply, Soft touch “TRUE BYPASS” relay system rated at 200,000 cycles and STILL no failure, dual layer epoxy glass circuit board with embedded traces, bullet proof “Touring Pro Construction Design”.
This is the ultimate pre-amplification unit. A single Stomp switch, BIAS knob and LED status indicator. It is the most transparent pre-amp / clean boost pedal on the market. It will enhance the sound of any amplifier without altering the tone of your guitar. It has the ability to act as a clean boost, or with the BIAS pushed higher it is capable of pushing any amp into beautiful harmonic breakup, overdrive and distortion. This unit should run first in your chain, and in most cases you may just want to leave it on all the time, as a clean boost, especially if you follow it with another pedal or two to handle the distortion chores. Your amp will have never sounded this good without it. It makes such a dramatic improvement in the sound of your amp that you will wonder how you ever got by without it. Imagine being able to reach inside your amp and BIAS it hotter to any degree, at any time.. This is what this unit does.. Credit: Lovepedal.
