ECC83S preamp valve/tube:
It’s a fact that JJ electronic preamp valves are one of the best for rock & blues!
This ECC83 valve does high gain effortlessly with low microphonics & minimal noise. The dynamic response & harmonics jump out whilst the tone remains full & clear under overdriven conditions without losing definition, essential for high gain lead lines.
We like this preamp valve & include it in many of our kits due to its versatile tonal range when used in either clean or distorted applications. A big favourite with Marshall & Fender tube amp owners.
