Crystal Clear Boost

I run this boost after my overdrives simply as a volume gain and it is quite simply the best sounding boost I tried. I AB'd it with an Xotic, TC, Duncan and several others and it was the only one that didn't add flavor to the sound, I'm a bass player using a Spector NS2 and this pedal is wonderful with it!

Pigtronix Class A Boost works like a dream!

This unit works great! If you just want a db boost for solos that does not change your tone, look no further. The Class a Boost works very well with clean and overdrive tones.

Great boost pedal

I use this pedal in my effects loop on my Orange Rockerverb to boost my leads. It works great! It also works great into the front of the amp. Great boost pedal!!

Use the 18-volt option

This pedal not only gives you a clean boost, you can drive a high gain channel with it to thicken things up too. Much more headroom if you use the included 18-volt adapter. It doesn't change your guitar tone at all and it's whisper quite. I'd have given it a five stars if it were more potent with 9 volts of power.

Does What It's Supposed To

While I haven't used it this way yet, I am sure it will work great when I want to boost the signal just a bit in passages of a song while recording. It is clean and pretty quiet as well.
