I've had this on my pedalboard to offset noise, loss of gain, etc from my effects chain. Recently added a Radial Boost that has a built in buffer so no longer need this. From the Pure Tone website:
"After many years of absence, Pure Tone is finally back! The famous buffer that is in all Visual Sound pedals is now available in a new, tiny, Custom Shop package. Put it first in the chain of effects, plug in your input and output cables and a 9V power supply (like the 1 SPOT), and your guitar will sound like it's plugged directly into your amp with a short cord. Its that simple, and yes, it really works. Completely eliminates cable capacitance and tone sucking.
Size: 2.5" x 2.37" x 1.2" (63 x 60 x 30mm)
These sell new for $50, will ship to you in CONUS for $25. Rather see it get used than sitting on my shelf..... Attachment 375802
